There are many important ores and medals deep inside the earth. The only way to get them out is through extensive mining. Mining is a back breaking, grueling process. Mining machines have helped to streamline mining by speeding up the process and creating safer working conditions. Mining machine operators run these machines and keep them working properly and efficiently. Many skills must be mastered before becoming a mining machine operator.

Physical Skills

Even though mining machines are designed to lighten some of the physical load of mining, a mining machine operator must possess advanced physical skills. He must be able to move multiple limbs at any given time. For example, he may need one hand to steer the machine, another hand to control the digging apparatus and one foot to press the gas pedal. He must have steady arms and hands. Shaky hands at the controls can cause sudden jerking motions that could contribute to accidents in a mining situation. They must also have good reaction time in case of a sudden dangerous situation. In these cases, depth perception, hearing sensitivity and far vision are also essential. These skills help to spot and avoid problem situations before they occur.

Mechanical Skills

A mining machine operator must have advanced mechanical skills. He must be able to operate the controls of his machine precisely and quickly. A minor mistake with advanced mining equipment could cause potentially dangerous accidents. He must be able to quickly pick up techniques on the controls of multiple mining machines. She must be able to intuitively pick up on any training necessary for the job. Miners must have a deep knowledge of their machines and the tools necessary to run and repair them. Quick repairs may have to be done on the fly, and mining machine operators must be able to spot these repairs and do them quickly, yet effectively.

Other Skills

Besides physical and mechanical skills, a mining machine operator must possess a wide range of knowledge about mining and know how to apply this knowledge. He must understand the raw materials he is mining in order to use the best mining methods for that material. He must have deep knowledge of the laws, regulations, precedents, agency rules and any other legal information regarding mining and the operation of mining machinery. Public safety and security must also be in his mind at all times. Training and education of other mining workers are also skills vital to his job. He must understand how to run a business effectively and how to be as efficient as possible to save his company money.

A fertilizer spreader is a metal hopper with an adjustable trough underneath for applying an even layer of fertilizer over lawns and gardens. Some spreaders connect with a tow hitch to the back of a tractor. Smaller models have a handle and wheels for pushing the spreader yourself. As with all garden tools, cleaning your spreader after each use will prolong the life of the equipment and ensure proper operation. A garden hose may be used, but a power washer works best.

1. Empty the hopper of all fertilizer, either by spreading the product on your garden or lawn or removing the fertilizer and returning it to its storage bag.

2. Open the hopper trough at the bottom of the spreader so water can run through. Pull the lever on the side of the spreader to open the trough.

3. Wash the spreader inside and out with a garden hose or power washer. The power washer works faster to remove fertilizer particles that may have dried and hardened on the equipment.

4. Wipe down the spreader with old towels to remove excess water, and allow the equipment to air dry completely.

5. Pour machine oil on an old towel to wipe down metal parts, concentrating especially on the hinge mechanism at the bottom of the spreader trough.

With the development of industry, coal ash with processing and utilization has expanded largely, and the large-sized vertical mill must become the first choice for the future coal ash processing industry. Fine ash collected in the ash air burned by coal is called coal ash, which is the main ejection of solid waste. Plus according to the technological development of mill, large-size grinding mill can achieve the way of one-time micro-powder processing. After the grinding, the coal ash has the characteristic of fineness, epigranular, surfactivity, which can save a lot of cement material when adulteration in the concrete cement to increase the plasticity and stability of concrete cement. Even there is a standard of 8% of coal ash into the different clinker to make finished cement. What’s more, coal ash has been widely used into concrete additive, hollow brick, ceramics and padding material in building construction.

With the boarder utilization of coal ash, the correspond coal ash technology has a higher requirement, with the traditional Raymond mill, ball mill cannot satisfy the demand of handling capacity and fineness so the new type of vertical mill, high pressure suspension mill and high pressure micro mill must become the mainstream equipment with its newest technological achievements and convenient usage with high efficiency.

Henan Hongxing Machinery is one of the primary mining machinery manufacturers based in China. All our mining machinery including fertilizer production machines are designed based on latest production technologies.

Currently, we can produce variety of different fertilizer equipment, including disc granulators, rotary drum granulators, dryers, fertilizer cooling machines, and screening machines, etc. Owing to their simple structure, convenient adjustment, superior performance, long service life and environmental protection, our fertilizer equipment is widely used in fertilizer manufacturing industries for transportation, drying, cooling and screening non-glutinosity materials.

Fertilizer equipment comes in several forms. Many pieces are designed specifically to apply various kinds of fertilizer. Other pieces that can be categorized as fertilizer equipment include mixing tanks, holding tanks and equipment specifically intended for use in applying anhydrous ammonia to agricultural land.

Dry forms of fertilizer are usually applied with a type of fertilizer equipment known as a spreader. Drop spreaders dispense fertilizer from the bottom of the holding container through a mechanism that regulates the rate of application. Broadcast spreaders throw the fertilizer in swathes around the equipment. Both drop and broadcast spreaders come in a huge range of styles and sizes ranging from hand-held units for small home gardens to giant pieces of equipment that are towed behind agricultural tractors.

Liquid fertilizers are applied using sprayers. The most common type of sprayer for use in yards and gardens is a tank small enough to be carried by hand or on the operator’s back. The fertilizer flows through a hose with a spray nozzle on the end. Fertilizer equipment for spraying on a larger scale normally has a row of nozzles mounted horizontally on a pipe that attaches to a tractor or other vehicle. These are called boom sprayers and also come in a range of sizes.

Specialized fertilizer equipment is necessary for use with anhydrous ammonia, a source of nitrogen for fertilizing large areas. Anhydrous ammonia is stored as a liquid under high pressure and becomes a gas as it moves into air at normal pressure. The liquid is very cold, caustic and corrosive, so it must be handled carefully. Storage tanks, hoses, nozzles and other parts of the spraying equipment used for anhydrous ammonia must be carefully designed and maintained. Anhydrous ammonia becomes a gas at normal pressure, so the fertilizer equipment injects it into the ground instead of spraying it on the surface.

Papermaking is the process of making paper, a substance which is used universally today for writing and packaging.

In papermaking a dilute suspension of fibres in water is drained through a screen, so that a mat of randomly interwoven fibres is laid down. Water is removed from this mat of fibres by pressing and drying to make paper. Since the invention of the Fourdrinier machine in the 19th century, most paper has been made from wood pulp because of cost. But other fibre sources such as cotton and textiles are used for high-quality papers. One common measure of a paper's quality is its non-woodpulp content, e.g., 25% cotton, 50% rag, etc.

No wood, no water, use the 'rock paper', you heard it? This is known as 'rock paper' The advent of new technology, known as the traditional paper and packaging materials in the field of a major technological breakthrough. Different from traditional paper timber, paper, stone, the main raw material is most abundant in the crust of calcium carbonate mineral resources, as well as 20% of other accessories and additives as raw materials, production of processed polymer processing technology, a breakthrough was followed 2000 years in wood pulp, straw pulp as raw material, paper making technology. Rock paper technology, is the most abundant mineral in the crust of calcium carbonate as the main raw material resources to a variety of polymer materials and inorganic substances as auxiliary materials, use of filled polymer interface chemistry and modification, a special processing and into a reversible cycle of use, technical characteristics of modern technology the new paper. The birth of the technology, not only to solve the traditional paper making pollution on the hazards in the environment, but also solve the Daliang caused by the use of plastic packaging white pollution and waste a lot of oil resources issues.

The main part of paper-making process stone is rock grinding, rock paper directly affects the toughness of paper, and break resistance, waterproof and oil and other characteristics. There are many rock grinding equipment, such as raymond mill, high pressure suspension mill roller, vertical milling machines, milling machines and other European milling process can be completed, but the stone paper, the extraction of rock in calcium carbonate, then the purpose of ore ground into fine powder calcium 1500-2500, followed by a second process, will add on 85% of modified calcium carbonate made of 15% of the additive masterbatch, and finally through the extrusion blown film equipment made of paper or bags.

A modern paper mill is divided into several sections, roughly corresponding to the processes involved in making hand-made paper. Pulp is refined and mixed in water with other additives to make a pulp slurry, the headbox of the papermachine (Fourdrinier machine) distributes the slurry onto a moving continuous screen, water drains from the slurry (by gravity or under vacuum), the wet paper sheet goes through presses and dries and is finally rolled into large rolls, often weighing several tons.

Compared to the traditional paper technology, rock paper technology without wood, without bleaching, no waste water pollution, protect forests, protect the environment, a new technology to benefit mankind.

Cone Crusher is a kind of new type crusher who adopts the new crushing concept, its structure principle entirely different from Jaw Crusher, hammer crusher, Impact Crusher and other crushing machine. Its Crushing capacity and unique production ability are other types of crusher can't be compared.Cone crusher is divided into spring cone crusher and Hydraulic Cone Crusher, suite for crushing the stone and rock which hardness is above average.

Cone crusher is dividing in to standard type, short type, generally used in middle and fine crushing. Standard type, generally used in second crushing, Short head type, generally used in fine crushing.Spring cone crusher has four Chambers that is especially coarse, coarse, medium, small type.The principle of selection is to look at the feed particle size and particle size of the decision to discharge into the Liao duo large, coarse particle size, choose special coarse or coarse, and vice versa type of medium and fine. In the calculation of particle size, the open side with the largest population size multiplied by 0.85 feed into the material size as a selection based on the average size of the product is divided by the maximum feed crushing ratio.

Spring cone crusher standard used for open loop, short head type is used for closed loop. When choose the scale board, users consider three factors generally, that is capacity, power dissipation, wearing resistance of the scaleboaed. Should be abbey the following principle: Maximum feed size; size changes to the particle size distribution; material hardness; material wear resistance? The higher the longer the power liner, hard-liner material selection is short, long soft liner material selection, the distribution of the material, fine material selected short liner, long liner thick material selection. Feed particle size distribution, in general, less than the closed side of the nesting population cannot exceed 10% of the material, if more than 10%, the increase in power consumption, product size becomes flaky. Viscous material increase in the amount of moisture can affect the throughput of materials; the material is water, generally no more than 5%. The use of the power, the cone crusher should pay attention to following issues when in operation, can make sure the normal work for machine.

Cone crusher at work, feeding should be uniform, not segregation. If the feed to reduce production capacity will be uneven, the product particle size is too large, the spring moves frequently, Bowl-bearing pressure, power consumption increased. Have iron device; to prevent the crushing chamber through iron, iron if too frequent, it may cause broken accident

In these economically challenging times, it's more important than ever to buy equipment wisely. The right equipment can help your company weather economic ups and downs, but a bad purchase can hurt your ability to compete. It's crucial to analyze the pros and cons of each purchase, including the potential return on investment. In fact, buying new equipment may not be the best option; it may be wiser to buy used equipment, lease or rent, or to avoid acquiring machinery entirely.

Making the right equipment purchase

Be sure you have answers to these questions before you buy. Avoid being influenced by aggressive marketing campaigns that make unrealistic claims about technology or equipment. Every business reality is different.

Be innovative

In today's competitive business world, being innovative in everything you do is a key to success. Innovation is really about responding to change in a creative way; one way to do so is by acquiring equipment or technology that helps you improve your efficiency. For instance, your new equipment might help you streamline your operations and create better products and services that appeal to a niche market. New technology might also be useful in your research and development efforts or in improving customer service. Above all, you want your customers to know that you're investing in innovation; it's a clear message that you have their evolving needs in mind.

Know your financing options

Every method of financing has advantages and disadvantages, so carefully evaluate each option. The factors to be considered vary from one company to the other, depending on your company's credit record or line of business.

Think safety first

A healthy and safe work environment means your employees and your company can be more productive, and this rule applies to your equipment and technology purchases as well. Your suppliers are responsible for selling you equipment that can be used safely, but you are responsible for ensuring that your employees follow safety rules. For more information, visit Workplace Health and Safety, a site run by Human Resources and Skills Development Canada.

Keep it green

When purchasing equipment or technology, be sure that it's energy efficient. Not only will you be saving money, but you'll also be contributing to the health of the planet. Research the environmental impact of your new equipment. Find out how to dispose of your existing equipment in a way that minimizes its negative impact on the environment.

Interested in saving money on a backhoe, loader, jaw crusher, sand maker or belt conveyor? Sometimes, buying used mining, construction or heavy equipment is a smart way to go and makes sense. Other times, you'd be better off going home empty handed. Here are a few ways you can make sure you get a good deal on used construction equipment.

Look carefully...

Go over the used equipment you're investigating slowly and carefully. New paint jobs are relatively cheap and can cover up a lot of problems. Look for evidence of rust patching or cover-up – poke suspect areas with a tool to be sure. Check underneath the vehicle for evidence of leaks. Inspect hoses and valves before and after the test drive, so you easily spot fresh leaks.

... but use all your senses

When you're testing out used construction equipment, don't go by your eyes alone. Listen to the engine and the hydraulics as you're testing it out – is the machine straining more than it should? After it's been running for a while, are there any smells of burning oil or electrical problems? Do the controls feel as responsive as they should?

Review Maintenance Records

Most users keep a history of all the maintenance repairs performed to the equipment. Many log hours against the actual components and requesting these would be very prudent and helpful for your assessment. Engine hours may differ from hours on hoist cylinders or tracks for example so understanding the life of components will help you determine fair market value.

If possible, buy from established companies or dealers

You are much more likely to have problems if you buy used construction equipment from individuals or a business that does not focus on construction or mining. Mining Machinery companies have several advantages when it comes to used equipment:

a.They have a reputation in the industry;

b.They know that if you're buying used equipment now, you're likely to need more equipment in the future and making sure you are a return client is important to them;

c.They have regular P.M. schedules and equipment is likely to be better maintained then if purchased from a small unknown company;

d.They're better able to inspect and repair any potential problems with the equipment as they have the staff on hand to maintain the equipment;

With these tips in mind, you should be able to find a used piece of construction equipment that can still get the job done.

Tucked away in the northeastern section of Beijing just outside the Fourth Ring Road stands what was once the pinnacle of Chinese industry. The scale of China's manufacturing capacity and its domestic market for machinery are remaking the industry's international landscape. China's dynamism presents opportunities for foreign machinery makers as an export and investment destination, as well as an up-and-coming source of capital. Mining machinery is the machines directly used for the mineral mining and beneficiation, including mining machinery and mineral processing machinery. Broadly speaking, exploration machinery also belongs to mining machinery category. In addition, many other equipments like cranes, conveyors, fans and drainage machinery are also applied in mining operations.

Mining machines are the equipments used for the exploitation of valuable minerals including digging machinery for the mining of metal ores and non-metallic minerals, coal mining machinery for the mining of coal, oil drilling machinery for the exploitation of oil, etc. The first wind moving wafer shearer was designed by a British engineer named Walker, and was successfully manufactured in about 1868. Beneficiation is the process of choosing valuable minerals from the collected raw materials according to their differences in the physical properties, physicochemical properties and chemical properties. The machinery that implemented this choosing process is called beneficiation machinery. Beneficiation machinery can be divided into crushing, grinding, screening, sorting and dehydration machines. The commonly used crushing machines are jaw crushers, gyratory crushers, cone crushers, roll crushers and impact crushers and so on. Drum mill is one of the commonly used grinding machines including rod mill, ball mill, pebble mill, etc. Hydraulic and mechanical grading machines are widely used in wet classification work.

China's main cost advantage is, of course, inexpensive labour. As a corollary of having the world's largest population, China also has the world's largest labour force. The machinery industry alone currently employs around 20 million people, and they are paid wages far lower that those paid in any other major machinery producing country. Much of the resulting cost savings are then transferred to international consumers via lower product prices for exports. Although wages in China have increased substantially in recent years, the average rate of USD 0.40 per hour in 2008 was well below the rates of the US, Japan and Germany, all with hourly wages above USD 20.

Currently there are two problems existed in China's mining machinery industry. First, the comprehensive strength of the mining machinery enterprises is not strong. The majority of enterprises are at a standstill of energy and capital investment in scientific research, new product development, technological innovation and enterprise management. Variety of domestic mining machinery products can not meet the various requirements, especially the critical needed key equipments for the national construction. And there are problems of low technology content, low additional value and unstable quality of products, low labour productivity and so on. Second, a series questions of product variety, technology, quality, service, etc. have led to the low actual contribution rate of the mining machinery industry to the domestic mining industry. Henan Hongxing Mining Machinery Co., Ltd. lays much emphasis on the quality and clients. We serve clients with the quality guideline of being responsible for every working procedure, every product and every client. What we have done is for the clients and we believe that quality is the best way to develop market. All of the products have passed the authentication of ISO9001. Hongxing Brand is the Chinese Famous Brand. Reliable and stable quality is the key to success. Our products are well known at home and abroad. Now we have tens of thousands of users throughout China and more than 30 world markets.

As China's machinery industry continues to progress, the question for the international manufacturer is how to react. A number of strategic options are available for international firms to integrate their businesses with China's machinery-making potential. Although China is the world's largest exporter of machinery, the opportunity still exists to export to and invest in certain products to China, particularly for innovative products using cutting-edge technology. It is often a matter of pride for Chinese manufacturers and a symbol of quality to have foreign-made capital equipment. When touring a Chinese factory the manager will often boast of possessing a German or American-made production line. The reputations conferred by the brand names of international companies still outweigh those of Chinese brands—Caterpillar is far more renowned than Henan Hongxing. Foreign firms are also noted for their after sales service, an area still relatively unemphasised by Chinese companies.

In the 1970s, China's financing and construction of a 1,870 km-long railway giving landlocked Zambia access to the Tanzanian port of Dar es Salaam was a monument to Chinese engagement and solidarity with Africa in a previous era. In a flush of post-colonial exuberance, Africa was undergoing a construction boom. The China that built the railway in Africa in the 1970s is a distant shadow of the China of today that routinely builds railways, roads, ports and other infrastructure in various parts of the world. In the 2000s, as the size of China's economy in quick succession surpassed that of Italy, France, the UK, and Germany, China's energy consumption expanded four times faster than expected to 16% of global demand in 2006.

Instead of a boom of new steel and concrete, Africa experienced decades of lost growth. In 2008, the World Bank estimted that access to the most basic services in Africa increased only modestly between the early 1990s and the early 2000s, and only slightly in the last decade. Electricity, for example, is still available to little more than 20% of Africa's total population, and piped water to just 12%.

Yet now a new China with vastly different priorities and strategic outlook is back in Africa, where it is instrumental in Africa's new construction boom that is reshaping the business landscape on the continent. In contrast to its piecemeal interaction with African countries in previous decades, China is now comprehensively engaged with almost all of Africa's 54 countries – lending money, providing aid, trading, investing, and more than all else: building infrastructure and extracting resources. This over-simplified description of China's business in Africa goes to the heart of how Africa's business landscape is changing under the influence of a new superpower hungry for natural resources and well-suited to provide Africa with something it is sorely in need of: infrastructure.

Along with the US and emerging economies such as Brazil and India, China's imports from Africa are as expected characterised by a disproportionate share of oil and minerals. China's trade with Africa has as a result been very lucrative for resource-rich African countries, and these African commodity suppliers have become crucial suppliers for China. South Africa is China's only African trade partner from which it imports substantial amounts of products that are not resources, while China's leading suppliers of oil (Angola), Manganese (South Africa), chromium (South Africa), cobalt (the DRC), and platinum (South Africa) are all African.

In 2011,Janpan earthquake, China contributed amount of people and finance, and also machinery such as excvavtors, cranes, jaw crushers, impact crushers, belt conveyors and so on. Africa is now China's largest market in terms of contract revenue with 41.1%, even more than Asia with 36%. Similar to Chinese trade and investment in Africa, the revenue of Chinese contractors is highly concentrated in a few resource-rich countries. In 2009, the leading six countries (Algeria, Angola, Sudan, Nigeria, Libya and Ethiopia), mostly oil and gas-related economies, accounted for USD 18.1 billion or 71% of China's total revenue (see chart below).

In April, a Chinese official acknowledged that China is on the verge of overtaking the US to become the world's biggest consumer of energy. To keep up with demand, China's natural gas imports more than doubled to 6.3 billion cubic meters in Q1 2011 from a year earlier. China also plans to invest RMB 400 billion (USD 62.54 billion) in the construction of four hydroelectric dams to boost the share of non-fossil fuels in national energy consumption. Wind power is also a part of this strategy as China will boost its offshore wind power installed capacity to five gigawatts to form a complete technological and industrial chain.

An uncertain global economic outlook due to the ongoing debt crisis in the Euro zone and the recent downgrade of the US debt rating, along with a large scale power crisis during the busy summer season are threatening to slow China's growth in the second half of 2011. However, looking to diversify its export destinations and build upon its status as the world's second-largest economy, China has continued to increase its footprint around the world, with Premier Wen Jiabao signing USD 15 billion worth of deals in Germany in June along with an additional USD 4.3 billion worth in the UK.

In April, Shanghai Electric Group Co. announced it had won a USD 1.1 billion contract to expand a natural gas-fired power plant currently under construction in Zubaidiyeh, southeast of Baghdad. The company also announced in April that they had signed an agreement with KSK Energy of India to export 125 units of 2 MW wind turbines to India, which marks Shanghai Electric's first major international wind turbine sale. The company expects India to become its largest export market, absorbing half its exports including wind turbines and thermal power units.

It was reported in August that Apple is currently in talks with China Mobile, the world's largest carrier by subscribers, to officially introduce the iPhone on the carrier's home-grown TDSCDMA network. A mutually beneficial deal would help Apple meet upwardly mobile Chinese consumers' growing demands for its products, while helping China Mobile attract more 3G subscribers. Although it seems unlikely that Apple will meet its target of opening 25 stores in the mainland by 2012, its four existing stores are the most heavily trafficked Apple stores in the world.

According to a report by Off-Highway Research (a consultancy specialising in the research and analysis of international construction), China's share of the global construction machinery market jumped from 18% in 2002 to 32% in 2009 in terms of sales volume (see chart above). China's three leading pioneers in this regard are Sany Heavy Industry, Zoomlion and XCMG, which have emerged as the three dominant manufacturers that together account for about 30% of the market in China, larger than the top three foreign companies active in China (see chart below). Indeed, these three are now ranked in the top ten in terms of sales revenue globally.

Though the industry in China is highly fragmented with over 900 companies vying for market share, a majority of them only manufacture components or engage in sub-assembly due to the hefty upfront financial investments that are required. In addition, intense competition between both domestic and foreign participants as well as rising demand for improved and advanced technology have forced small operators to either be acquired by more established players or simply exit the game.

It is worth noting that foreign enterprises have had little opportunity to compete against local competitors in this consolidation drive due to regulatory restrictions, and have been unable to acquire majority stakes in joint ventures with domestic firms. This has allowed local rivals to gather market share from foreign companies and at the same time narrow the capability and quality gap by integrating independent enterprises' abilities via strategic acquisitions. Moreover, foreign enterprises have simply not been able to increase production fast enough to meet rising demand, diluting their market shares.

Over the years, Chinese companies in various industries have successfully moved up the value chain by offering a wide range of products and the construction machinery industry is no different. Foreign companies have historically served the Chinese excavator market by leveraging their strong expertise and precision quality. Yet according to CCMA data, Chinese companies now control one-third of the global excavator market, up from 22% in 2006. Such strategic moves have undeniably boosted their overall competitiveness and allowed them to capture market share from their foreign competitors in China and in other emerging markets.

China's three leading construction machinery manufacturers seem well placed to achieve these goals, yet each of them still have much potential to improve their technology. To be sure, to enhance their competitive position, Chinese machinery manufacturers are constantly upgrading their technological capabilities and focusing on technical innovation, but they still have some ground to cover before they start taking on the world leaders. That said, these firms have demonstrated a remarkable ability to incorporate technology and quickly adapt. As a case in point, Sany invented the first 66-metre truck-mounted concrete pump in the world.

Among these key differences, there is one commonality that exists in the internationalisation strategy of all three of China's major machinery manufacturers - they have been aggressively marketing their product overseas though new distributing channels with a core focus on emerging markets, namely Brazil, Russia, India and Africa. Emerging markets are sweet spots for these companies because it is difficult to access developed US and European markets where dominant and established players, such as Caterpillar, emphasise their value-added after sales services. Emerging markets, on the other hand, are more price sensitive, and prices of machinery equipment from Chinese manufactures are typically 15-20% below foreign competitors, providing buyers in emerging markets with a considerable overall cost saving. Another important reason is that, like China, these countries are experiencing a similar urbanisation process and are consequently investing a lot towards infrastructure improvement, providing Chinese enterprises a potential market to tap into.

Machinery manufacturing industry is a pillar industry of national economy. Modern manufacturing is changing people's mode of production, lifestyle, business management as well as social structure and culture. As China's potentially existed large market and abundant labor resources, the world's manufacturing industry is being transferred to China.

China is becoming a world manufacturing power. With the continuous development of times and the promotion of the Internet, the development of China's machinery industry has made tremendous contributions for the world's machinery industry. For a long time, the major factors restricting the development of China's machinery industry have been the capital and technology. Now the national automotive industry policies, the national western development, national debt capital investment and other macroeconomic policies have driven the demand market for machinery products. Both private capital and foreign capital poured into the machinery industry has eased the financial difficulties of the mechanical industry. International cooperation and communication have created the conditions for the upgrade of mechanical products.

Machinery industry covers a wide scope, and there are strong correlations between each other. But the development of various sub-sectors are not consistent. In the overall machinery industry, sub-sectors which are of rapid growth include machine tool industry, engineering machinery industry, heavy machinery and specialized equipment basic parts industry. China's machinery share of the world's market continues to expand, for example, China construction machinery accounted for 15% of the global market. The global construction machinery market is of about 180 billion US dollar, and China accounted for 15% share of the total. There are plenty of rooms for China's future machinery industry development. And, China's mining machinery industry is also of important position. China's mining machinery accounted for 85% of the world's market share. Therefore, for the current situation of machinery industry in international and domestic market, the domestic machinery industry need to use modern advanced technology to take more domestic and international market shares.

Through years of research, it is found that many of the machinery industry businesses gradually began to use the Internet to promote their own products and websites. In fact, the enterprises who promote their businesses trough the use of the Internet have got the benefit three percent more than the common enterprises. But there is a gap between the many companies who use the Internet, so the benefit can not be too obvious. The professional of a business website is the basis to reflect the network marketing effect. There are large numbers of machinery enterprises, which is one of the most competitive market in the traditional business areas. For the development of online machinery business, it is necessary for the machinery enterprises to research the situation of their own website. It is of great value for the development of effective business network marketing strategies.

Therefore, the machinery enterprises could grow their own business by making full use of their own network advantage. As the integration of world economy and the accelerating of globalization, the electronic industry technology has been widely used in the international trade and the application of e-commerce is becoming a more and more popular way for our country and the enterprises to connect with the international environment. The new operating mode of the international trade will play an important role in China's trade for its expansion of international trade opportunities, rise of trade efficiency, reduction of trading costs and enhancement of the enterprises' competitiveness and adaptability.

It is because of China machinery industry in general are still in the development stage in vulgar, machinery industry unit product comprehensive energy consumption than to the high number of developed countries, but the value added of industry rate than developed countries low many. With tools industry as an example, China’s high speed steel paper cutting tool material price than the international market is cheap, cemented carbide cutting the price is less than a third of the Japanese. According to the China machinery industry federation of key enterprise of sampling survey,Wet magnetic separator in the first eight months of this year new orders increased 3.8% year-on-year, growth down significantly more than the same period last year. New orders because not much, enterprise development situation of side less confidence, especially large amount of wide of the small and medium-sized enterprise situation is difficult. According to understand, to overcome obstacles rapeseed growing seasonal, the municipal agriculture department and agricultural closely with the farm machinery, on the one hand, the plant variety improvement in exploring optimal collocation, on the other hand, the effort to find a suitable for huzhou the practical need agricultural machinery, help the farmers from heavy manual work freed, achieve a variety of charge, speeding up the process of agricultural mechanization.

In foreign demand in the short term is not optimistic. The China machinery industry federation President WangRuiXiang think, China machinery industry remains industry itself big but not strong, independent innovation ability weak, the foundation behind, low level manufacture level of repetitive construction,Limestone dryer product technical content is not high, the added value of the industrial concentration is low, the industry chain not perfect, industrial structure imbalance and excess capacity and serious long-term structural contradictions. And, developed countries based on the resource configuration optimization objective need, but also trying to solidify China as the world of the equipment manufacturing industry of high-end assembly and ZhongDiDuan processing base.

To speed up the enterprise merger and reorganization products renewal, form the host production enterprise mainly by the single machine manufacturing to system integration give priority to change, professional parts production enterprise to “specialized, refined, and unique” direction development, formed complementary advantages and coordinate the development of industry structure.

Therefore, 1025 period, domestic mining machinery market will enter a new stage of the upgrade. In a large market demand to the Chinese market with all of the transfer of the case, the Chinese market will join the international market leader. Data shows, the annual production value of international mining machinery in rising state, but the current domestic market share still points less, belong to the typical “reserved”. Although the domestic market development space is wide, but in the increasingly fierce competition of the international market, the domestic mining machinery is still at a disadvantage. As is known to all, China mining mining and processing of the tailings left behind is great, if the accumulation of the tailings are already up, light this resources can use 20 years. Generally with the emissions of tailings can be made into artificial sand, can solve every year 20.4 million tons of construction with sand, which solved the problem of tailings environmental pollution and resolve the problems in construction sand resources, kill two birds with one stone.

Rising demand for such vehicles indicates rapidly increasing activity in the mining sector.

'Since early 2010, the mining sector has steadily gathered momentum and this has had a positive impact on the sales of (earth-moving equipment) as local mining conglomerates gear up to produce and deliver huge quantities of coal, chromium, iron ore and other metals,' said Colin Squair, Wesbank’s head of finance for heavy machinery.

'Another factor motivating growth is the active replacement of plant (heavy machinery), as during the economic downturn many companies operating in the commercial sector held off on replacing their ageing equipment,' Wesbank said. Mr Squair said from 2009 to last year the market for plant fell off 50% but demand had improved this year.

Digby Glover, CEO of mining contractors TWP, confirmed yesterday that there had been 'delays in the project pipeline' as a result of the financial crisis, and that now 'there’s suddenly a big catch-up'.

'Commodity prices are back to pre-2008 levels,' Mr Glover said, and the industry was scrambling to meet demand. In terms of TWP, he said the firm had 'maintained capacity in 2010 perhaps at the expense of short-term profit, but that’s paid huge dividends for us. We’ve hired 300 engineers and technicians this year alone.'

Mr Squair said that 'availability would be the major hindrance' for his division this year, as a result of the contraction of the plant sector during the financial crisis and because of the March 11 earthquake and tsunami disaster in Japan.

Antonie Fourie, Basil Read’s MD for mining, blasting and excavating, said yesterday 'tremendous growth' in mining across Africa and the world meant there was huge demand for plant and 'major delays' in supply. 'I have old plant that I need to replace, and if I want to grow I need even more.' Basil Read had spent R480m this year on plant alone, and waiting lists for plant were causing headaches. 'At the start of the year I spent R220m on plant without even having work for it.'

Strong global demand for minerals and other commodities promises to fuel demand for mining equipment for years to come. This is positive news for domestic steel suppliers, not just because of the large amount of metal used to make each giant mining truck or shovel, but because much of this equipment continues to be produced in the United States.

“Anything that has anything to do with commodities is doing well,” says Jim Hoffman, senior vice president of operations for Reliance Steel and Aluminum Co., Los Angeles.

“It appears that with commodity prices where they are, and mining demand up throughout the world—especially in emerging markets like China, India and South America—the market for mining equipment will continue to be fairly strong for some time,” says Bill Jones, chairman of O’Neal Industries Inc., Birmingham, Ala. Jones and other steel suppliers note that production of the huge earthmoving machines consumes a lot of plate, as well as shapes, tubing, beams, and carbon and alloy bars.

While some commodity prices have moderated in recent weeks, they are still high enough to warrant further investment in mining activity and equipment, says Eli Lustgarten, senior vice president of Longbow Securities, Cleveland. Globally, mining equipment is sold out for the year, he reports, with capital investments by mining companies forecast to grow 30 percent both this year and next.

Currently, all of the major equipment manufacturers are operating close to full capacity and have growing backlogs that extend out into 2012. “Right now, mining companies are profitable. As long as they continue to have capital to spend, they will buy new equipment,” Yengst says. “This is a replacement type of business. Mining trucks and shovels, much like major appliances, wear out and need to be replaced periodically. I think we will continue to see healthy backlogs into 2013.”

“Mining is a long cycle business. It takes five to 10 years to develop mines, so mining companies tend to take a very long view of the global economy,” says Sanders at Joy Global. “They aren’t concerned about quarterly fluctuations.”

All eyes are on China and India to determine how long these good times will last. “China accounts for 40 percent or more of all commodity consumption. As China goes, so goes the mining industry,” notes Popovich at NMA.

In general, equipment makers are being careful about adding too much new capacity, given the cyclical nature of the mining business, Yengst says. “They all realize there will be a time when customers either won’t need any more equipment or they won’t have the money to buy it.”

One quick way for a company to expand its product offerings is to acquire a competitor. Longbow’s Lustgarten reports that merger and acquisition activity in the mining equipment sector has picked up in the last year or two. In February 2010, Milwaukee-based Bucyrus International Inc. acquired the mining equipment unit of Terex Corp., Westport, Conn. Nine months later, in November, Caterpillar announced its intention to acquire Bucyrus in an $8.6 billion deal that has already passed muster with regulators and is expected to close later this year.

“The general consensus is that commodities pricing will remain strong and, as a result, demand for mining equipment should also remain strong,” says steelmaker John Ferriola, president and chief operating officer of Nucor Corp., Charlotte, N.C. Indeed, with other markets still lagging, the steel industry’s appreciation for mining runs deep. n

If the quartz content and water content are so high that hammer crusher or impact crusher cannot be used, two-phase crushing system should be adopted. In general, the double roller crusher, roll sizer, jaw crusher as well as cone crusher are suitable for the two-phase crushing system for abrasive materials. Their crushing ratios are much the same (about 15-16), but their adaptive capacity to hard or wet materials is quite different. The jaw crusher and cone crusher crush the materials by means of high pressure, and they can handle hard rocks with compressive strength up to 400Mpa. The double roller crusher and roll sizer are influenced by shear and pull force, and they are only suitable for crushing materials with compressive strength less than 175MPa. However, they can process materials with high viscosity and corrosiveness.

The selection of crushers for cement plant should take into consideration the following factors raw materials’ hardness (generally represented by the compressive strength), corrosivity (usually described with free quartz content), and viscosity (water content, and clay content). In accordance with the above information, you can make a choice.

Selection Criteria of stone Crushers:

Crusher TypeMax. Crushing RatioCompressive StrengthQuartz Content(％)moisture content(％)

Single stage hammer crusher1100＜150≤8＜10

Biaxial hammer crusher1100＜150≤8＜15~20

Impact crusher120＜175≤12＜8

Jaw crusher15＞150~400＞15＜5

Cone crusher15＞150~400＞15＜5

The requirements on limestone crushing are relatively high. After being processed, the particle sizes can reach 0~25/80mm. The crushing processes should be reduced to the greatest extent, so that the one-time investment and maintenance costs can be reduces. The hammer crusher or impact crusher with high crushing ratio can meet the requirements for single stage crushing, but the quartz content should be less than 8%-12%. In terms of the impact crusher, the water content of the materials should be less than 8%. On the part of the biaxial hammer crusher, the water content can reach up to 20%, and limestone and clay can be fed at the same time.

Hongxing conveyors are made of steel structures, protected from corrosion by hot dip galvanizated with zinc deposition on the surface, the drive end and the tail end are preassembled in the workshop the intermediate parts consist of two side walls and the central frame and are designed to have small footprint during transport, yet not compromising the sturdiness and solidity of the belt. The shaft and the drum of the either end are not welded but fixed by some rigid couplings to ease any replacement in case of damage of some parts (i.e. brake of a bearing, etc...).

A FULL RANGE

- Inclined conveyor belts: designed for use in conveyance of material up an incline, they are best used to transport aggregate to the different sections in a crushing plant.

- Bucket elevators: mainly used in sand production plants or washing plants.

- Extracting conveyor belts: usually used to extract the materials from feeding to crushing or screening.

- Horizontal conveyor belts: usually fitted with side walls and feet or trestles to convey aggregates horizontally.

Direct transmission with helical gearbox, pulleys and belts. Electric motor equipped with hydraulic joint to make the start of the conveyor sweeter, protecting the entire transmission. In its basic form HXJQ belt conveyors consist of a driving head pulley, a tail pulley, the moving belt, support rollers, cleaning devices, tensioning mechanisms and a structural frame. The classic transmission system through motor, belts, pulleys and gearbox is the guarantee of the maximun flexibility of use, offering the possibility to ajust the speed according to every need.

Supplied as standard is a belt scraper, a strong and anti-corrosive cleaning unit for easy maintenance and maximum belt cleaning efficiency. Hongxing Crushing Plants thinks it is vital to adopt a system of cleaning already in the conception of a coveyor, above all for those plants requiring a high standard of cleanliness. Our belt scrapers have an adjustable spring tension system: springs push the bar supporting the different scrapers, usually chosen according to the material to be processed. Amongst them, some scrapers have some widia inserts, highly resistant to abrasion and wear and particularly suited for abrasive and dirty materials. The use of belt scrapers reduce the loss of material, increase the plant capacity avoiding most of the wear of the return rollers, thus reducing maintenance costs and downtime.

To promote long, trouble-free life to every conveyor Hongxing Crushing Plants makes sure that the designer has designed it with quality components that can handle the entire range of forces generated in its use. One way to insure that is to engineer every part taking a load and then review the design calculations and the component selection.

In mining industry, crusher is usually used for crushing raw materials, with more than 8 mm thick. Crusher can be divided into primary crusher and fine crusher. Generally speaking, the processed materials can be 0.074 mm thick, or even smaller. The process is use outside force to crusher bigger materials into smaller.

In recent years, with excess capacity and homogeneity intensifies in China's crusher industry, which increased competition in the market. Some companies began to adopt some irrational promotions from buy product draw large domestic appliances to get prizes such as cars, small breakers until the introduction of mortgage purchase zero first-pay promotional measures.

In cement production, most of the materials need to crusher. Limestone takes a large proportion in cement processing, and has high hardness and large particles, so it also need to be processed by crusher. Jaw crusher, impact crusher, shaft impact crusher, and hammer crusher, they all widely used in cement plant.

As fast development of the society, the mounts of crushing material is increasing heavily, crusher plays more and more important role in our national economy.

Now , China crusher(hammer crusher, roll crusher) market opportunities have emerged , 'tiger ' will come here. Tiger said here ,including the macroeconomic slowdown , tightening of monetary policy , tough credit environment, including market advances , the adverse situation of excess capacity ,rising raw material prices increasingly, labor costs ,as well as emerging problem of adverse market order. Due to these 'tiger' catch-up,in the crusher industry more than a hundred Chinese Original Equipment Manufacturers and component manufacturers have started a super- scale long-distance race. It is the the competition between enterprises has become not only the competition between product quality, But also the competition for technology, markets, capital technology , services ,marketing channels, R & D capabilities , and many other elements.

Mining, extraction of solid mineral resources from the earth. These resources include ores, which contain commercially valuable amounts of metals, such as iron and aluminum; precious stones, such as diamonds; building stones, such as granite; and solid fuels, such as coal and oil shale. The search for and discovery of mineral deposits is called prospecting, or exploration. When a mineral deposit is found, it is studied to determine if it can be mined profitably. If so, the deposit can be worked or extracted by a variety of mining methods.

The mining industry is one of the most dangerous working environments. Mining equipments are instruments that are commonly used in extraction of minerals from the earth surface. In the past, ancient times, miners used to excavate minerals and metals by using simple hand held tools. With the introduction of automation and modernization, today’s mining world enjoys the benefit of many types of mining equipments that are used specially for mining purposes. Modern day mining equipment is powered mainly by electricity and hydraulic energy.

Mining equipments are available for various types of mining methods that are performed around the world. There are various types of mining equipments available in the world. Some of them are industrial shredders, drilling equipment, blasting equipment, drill rigs, hammers, mine winders, blasting machine, Mining Locomotive, well drilling machine, industrial crushers, cutting machines, drills, loaders, blasting devices, Track Drill, Rock Drill, etc. Some examples of mining equipment that is used extensively in mining operations are: hard hats, clothing/gear, ventilation fans, rock dusters, tractors, earth movers, water jet pumps, cutting machines, drills, loaders, blasting devices, dozers, trucks, cranes, fork lifts, draglines and many other machineries. A mining light system is important mining equipment used for all mining processes. A mining light system increases the efficiency and the speed of mining operations and guarantees optimum results in mining process. A mining light might consist of a heat sink, LED or laser, magnetic switch or a focusing cone. Gold pans, sluice boxes, metal detectors, digging tools, gold vials, snuffer bottles, etc., are equipments used for gold mining. Various kinds of large mining excavators are available for mining field. The mining excavators using advanced technology help in reaching the international level of performance in mining processes.

There are mining equipments available specifically for Surface mining processes such as open-pit mining, strip or area mining, quarrying, contour mining, mountaintop removal, and placer mining. For example, some of the Open Cast Mining Equipments are Rock Drills, Drifter, Paving Breaker, DTH Hammer, Wagon Drill, Slim Drill LD-4, Pneumatic Crawler Drill, TCT Drill Steel Grinder, and Cross Bit Grinder. There are excellent mining equipments available for Sub-surface mining processes such as shaft mining, drift mining, borehole mining, slope mining, and hard rock mining. Similarly, there are special mining equipments for deep underground mining processes such as Longwall mining, Continuous mining, Blast mining, Shortwall mining and Retreat mining. For example, some of the underground Mining Equipments are Junior Simba, Mucking Machine, Slurry Pump, Exhaust Fan, Air Mover, Cement Injection Pump, Pneumatic Power Pack, Turbo Light, Spare parts for Atlas Copco Drifter BBC-120F, Simba Junior, BMS-46 Feed Motor, BSP 10 Pneumatic Rod Catcher, Atlas Copco Cavo 310 Loader, Pneumatic Raise Climber, Eimco Loader & Hopper.

The use of right mining equipment is very essential for increased productivity. For example, the use of large mining equipment in surface mining maximizes the recovery through the excavation of one or more coal seam deposits in the large area surface mines.

Many features, restrictions and criteria need to be considered while choosing the mining equipments for a mining process. The two most important factors for choosing any type of mining equipment are its strength and durability. Cost is also an important consideration while selecting mining equipments.

Mining is a very dangerous process. If a wrong piece of equipment or tool is used for a specific mining purpose, it might lead to disaster. Therefore it is important that everybody involved in the mining operation must know exactly how to use their mining tools properly. Each worker should be properly and thoroughly trained to use every part of mining equipment they will be using. Also the workers should be educated about the safety measures in using the mining equipments.

When individuals hear about exploration, most will think about enormous trucks and bulldozers as the primary mining equipment. While this image holds true today, tools employed for mining have come quite a distance from its roots. Historic miners probably can't think about the existence of these devices. If you're curious to discover more, here are a couple of suggestions to get you started.

Mining operations can be large and complex undertakings. In order to keep things running smoothly and safely, you need to have the mining supplies on hand to make repairs and make sure your project is completed on time. For fast service and a variety of choices, search for mining equipment for sale online from multiple mining equipment distributors.

Many mining equipment manufacturers have detailed specifications and photos of their inventory on their websites. When browsing the offerings of a mining equipment manufacturer, look for deals on refurbished or used mining equipment. Find everything from dryers and kilns to screens and centrifuges. No matter how big or small, you can find the mining tools necessary for any type of mining operation, or any stage of processing materials. Find mine equipment for:

1. Drilling and excavating

2. Screening and feeding

3. Weighing and monitoring

In order to remove the resources you're after from the ground, you need a good drill. Whether you're drilling through rock, drilling wells, or searching for oil and gas, you need to be able to cut through the earth quickly and get what you need. Find an online supplier of excavation equipment for your specific mining task. In mines, conventional radios often won't work. In order maintain direct lines of contact, you need to install an underground communications network. Find a mining equipment manufacturer that helps design and install the perfect network for your mine.

At this time, gear utilized for excavation and extraction evolved. Some grew to become far more complex. As an example, trucks employed for exploration are now much more refined. Several trucks being utilized at present have electronic machines employed for dumping cargo and driving close to the mines. These motor vehicles might also be furnished with sophisticated suspension systems for greater driving performance.

Since the world continues to excavate for oil along with other valuable minerals, mining equipment is here to remain. In the future, this gear may have far more refined capabilities to make work simpler for all.

According to the China Construction Machinery Business survey, 26 of the main manufacturers of excavators in China sold 8868 units in September, 23.86% down. Excavator cumulative increase since February of this year climbed to the highest point, it has been declining for several months. China Construction Machinery Industry Association has predicted the next five years, the construction machinery industry is expected to be 17% annual growth. But now the growth target is being challenged. Growth in the second quarter of this year began the rapid decline in construction machinery industry had still not out of the signs down, the industry growth is still in the 'bottom.' Affected after construction machinery enterprises are expanding production capacity is becoming excess capacity.

Excavator sales decline in a row is typical of China's construction machinery industry reflected. According to industry experts say, since the second quarter this year, sales of construction machinery industry continued to decline, this phenomenon has not been checked in the third quarter. Zoomlion Chairman Zhan Chun new that the growth rate of decline in construction machinery industry, there have been signs of late last year, the first quarter of this year, industry unexpectedly explosive growth has actually overdrawn market demand, sales of construction machinery starting from the second quarter, a marked decline in . Railway construction slowdown, real estate is the construction machinery industry sales for the decline. Data show that the Ministry of Railways to complete the first nine months of capital construction investment 346.879 billion yuan, down 19.3%. National Railway in the third quarter ended investment for years the Great Leap Forward.

Data also shows that the first three quarters this year, China's fixed asset investment up 24.9% nominal growth (after deducting price factors, the actual increase of 16.9%), down 0.7 percentage points over the first half, shrinking demand for construction machinery industry downstream. Industry sales is to continue to decline or rebound in the fourth quarter? At the recent 2011 Global Construction Machinery Industry 50 Conference and Summit, insiders believe that the fourth quarter of this year may have tail phenomenon. However, many industry experts believe that the macroeconomic policies remain unchanged, the construction machinery industry will be difficult to return to the past growth rate. Institute of Finance, the State Council Development Research Center, Xia Bin, director on the warning, do not use the past to simulate the growth rate is derived future growth, construction machinery industry is facing the future development of more uncertainty.

In the industry under the background of slowing demand, the domestic construction machinery industry excess capacity problem increasingly prominent. And 'excess capacity' has become the focus of engineering machinery industry conference topics. ZhanChunXin the truth, construction machinery industry excess capacity are triggering industry malignant competition. Xugong group President and general manager of the rabbit liugong zeng pins identity construction machinery has appeared excess capacity. However, they think, industry excess capacity is the low end products of the excess, in high-end products field still have space. Four trillion yuan investment by pulling, engineering machinery industry become fast development, the related businesses expand the capacity to increase investment. A shares the main engineering machinery listed companies have or are almost through shares expand the capacity of financing. International experts will China enterprise overcapacity called it 'assembly excess capacity'. In order to deal with excess capacity bring industry competition, some large engineering machinery enterprise is calling on industry management department to make the industry standard, to regulate the market competition.

The construction sector is in an interesting phase of its evolution, not quite yet global in nature, but with some players active in more than one national market and the largest players becoming involved in multiple projects in Europe, North America, and Asia, particularly China. The sector includes companies from the smallest to the largest. At the bottom of the scale are small house-builders, followed at the mid-range by regional and national companies capable of handling multiple projects within one country, to larger players with specialist interests, for example, in shopping mall construction, or office blocks, operating in multiple countries. The industry has a clear overlap with civil engineering on infrastructure projects, particularly where groundworks and ground preparation for site construction are concerned.

The building materials sector is extremely diverse and constitutes a sizeable chunk of the industrial base of developed countries. It includes a highly diverse range of suppliers, from cement manufacturers (an area that is under tremendous pressure to both innovate and to “green up”), to specialty glass and steel manufacturers, as well as providing a large market to white goods manufacturers, furniture manufacturers, paint and wiring manufacturers, and a host of other related industries. According to some specialists, buliding material industry made great progress which brings new demand for mining machinery industry.

China's social scene of terrible 'class compaction' phenomenon. To put it bluntly, that is, a poor kid in today's society, through their own hard work, the success of the rich squeezed into the ranks of fewer and fewer opportunities than before. Only two categories of people in society: the poor and the rich. M based society, the impact on the real estate market is faced with the poor, the rich small family and face the 'luxury' will be hot. Of home building materials industry of the enterprises, located at two ends: the low end and high end brands and enterprises will live more moisture. Without an awkward position of 'the end' corporate and brand will live the worst, there might even be closed collapse.

Home and buildings designers and planners have to think about both materials and the building regulations that are likely to appear in a world dominated by calls for action to cut carbon emissions. Current building requirements are likely to be amended further, almost year on year, to minimize the impact of the built environment on the planet, which means cutting emissions and energy usage. We are at the dawn of “smart” buildings, which react both to energy usage and to the needs of occupants, but many leading architects and designers are already thinking about zero-emissions buildings, or massively taller buildings, or buildings that are themselves virtual “cities”—all concepts that will provide a fertile ground for innovation in building materials.

For further development, we must grasp the challenge to make innovation, do research and step into the road of Green Industry.

In recent years, low carbon and green has become an important trend in the development of the world, and this pure and fresh wind blowing in the will push green manufacturing to drive the science and technology innovation of the whole industry towards a brand new area and goes up for an unprecedented level. Some countries in the current world are building their green fortress by way of environmental protection, so green manufacturing is obviously a trend that accords with the development trend of modern economy.

More businesses are turning to green cleaning services over traditional chemical cleaning services. Read on to determine if green cleaning is right for your business and find out how green cleaning holds up to traditional methods. When you use chemical cleaning products regularly, you often forget how dangerous they are. By using chemical cleaning products, you are not only harming the environment, but also your health.

Several cleaning products are classified as ‘corrosive’. These are the chemicals that cause damage to organic material, particularly human flesh. When cleaning, you are using chemicals to clean away the dirt and grime. The more effective a chemical is in cleaning away dirt, the more damaging it will be to your skin. If it accidentally splashes in your eyes, it will do even more damage.

No matter how safely you use chemicals, how they are stored and how well we stick to the manufacturers’ guidelines, the reality is they still affect our environment. Many people release chemicals into storm drains, meant for removing excess water after a downpour. This has an extremely negative impact on our environment. Several cleaners release pollutants in the air, and the poisonous effect of these pollutants severely harms animal and plant life.

The only way to fight against polluting the environment is to seek safer alternatives for cleaning commercial facilities. Choosing products that have environmental attributes such as biodegradability, low toxicity, low volatile organic compound (VOC) content, and low life cycle energy use will minimize the effect on our atmosphere. It will help improve air quality and reduce water pollution, thus making our quality of life better.

Now mining machinery and equipment enterprise to pay more and more attention to the high efficiency, energy saving environmental protection equipment research and development and production. For example, mining machinery the short-lived, low energy consumption and reduce the life of the weight of the design principles.Jaw crusher supplier In practical production using low environment load materials, as far as possible, do not use freon,Jaw crusher supplier chlorine rubber, resin and asbestos and other harmful material. Parts of the waste treatment and minimize pollution comprehensive cost optimization, mining machinery products in initial stage design to consider scrapping a low cost and simple processing, less pollution, spare parts to collapse convenient, broken easy,Flotation cells can burn disposal or can be used as fuel recycling, etc. Use of renewable materials and resources, such as promoting the fuel cell mining machinery and geothermal resources mining technology and equipment.

The widespread popularity of green cleaning products with environmental agencies indicates that these are effective. Agencies such as EcoLogo and Green Seal certify products for efficiency, in addition to their health and environmental benefit. As for the costs, prices of green products have come down steadily in recent years. Moreover, usage of green products offers some ancillary benefits as well. Insurance companies may lower the premium for enterprises using green cleaning products. Recent studies also indicate that the use of these products boosts productivity.

China has been listed as a mining machinery production country, consumption and importing country, but it is big not strong. Based on the current situation, China manufacturing enterprises should further deepen the reform, actively adjust the industrial structure and products, transform the economic growth mode, enhance the ability of independent innovation, speed up the research and development and market expansion of high-end mining devices, mineral processing equipment, crusher equipment and the key parts, further improve product quality and strengthen the service consciousness, improve the comprehensive competitiveness of the industry, insist to green innovation avenue, only by which can they realize sustainable development of good and fast and finish the goal from big to strong.

In 21st century, 'low-carbon economy' is becoming recognized by the countries as the economic development model, China is no exception, the rapid development of economy and deteriorating environmental damage has brought unprecedented challenges to China's sustainable development and construction, the Government has to increase environmental protection legal system, to improve the low carbon environmental policy and law, to promote the harmonious development of low-carbon economy. In mining machinery industry, roll crusher as one of the key equipment also should suitable for the concept of low-carbon economy.

The coal industry began to introduce high efficiency and energy saving roll crusher to respond to the government call on environmental protection. More and more industries began to pay attention to energy saving and environmental protection. This is a challenge for most crusher manufacturers. The low consumption and green roll crusher equipment is the tendency in the future. In order to meet the need of consumers and respond to environmental protection call, Hongxing produced series of roll crusher machine with low carbon energy saving, green and environmental friendly. The new type roll crusher is widely used in coal, cement, silicate and other industrial department. The roll crusher can be divided into plain roller and tooth surface roller. The former used for grind material with medium hardness, the latter used for crushing brittle and soft materials.

The Roller crusher can be classified into double roller crusher and four roller crusher according to the roller quantity. The Roller Crusher bears the features of stable operation, easy maintenance, low cost, output size adjustable. The Roller Crusher can be used in the processing of fragile materials in cement, metallurgy, chemical, power generation, coal industries.

Working Principle Of Roller Crusher:

Through the feed opening, the raw materials fall to between the two rollers, after crushed, the final products drop naturally. When there are unbreakable materials or the material is too hard, the roller will concede automatically under the effects of spring and hydraulic pressure, which will widen the clearance between the rollers and make the hard or unbreakable so as to avoid damaging the machine. The clearance between the two rollers can be adjusted to change the sizes of final products.

There is a specific operating speed for most efficient grinding. At a certain point, controlled by the Mill speed, the load nearest the wall of the cylinder breaks free and it is so quickly followed by other sections in the top curves as to form a cascading, sliding stream containing several layers of balls separated by material of varying thickness. The top layers in the stream travel at a faster speed than the lower layers thus causing a grinding action between them. There is also some action caused by the gyration of individual balls or pebbles and secondary movements having the nature of rubbing or rolling contacts occur inside the main contact line. A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.

For the most efficient results, the Mill should be at least half filled with grinding media. Some operators prefer to go a little beyond the halfway mark to compensate for wear. There is no objection to this and we have been suggesting a limit of about 5 percent.

Cement ball mill rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls. An internal cascading effect reduces the material to a fine powder. Industrial ball mills can operate continuously, fed at one end and discharged at the other end. Large to medium-sized ball mills are mechanically rotated on their axis, but small ones normally consist of a cylindrical capped container that sits on two drive shafts (pulleys and belts are used to transmit rotary motion). A rock tumbler functions on the same principle. Ball mill manufacturers are also used in pyrotechnics and the manufacture of black powder, but cannot be used in the preparation of some pyrotechnic mixtures such as flash powder because of their sensitivity to impact. High-quality ball mills are potentially expensive and can grind mixture particles to as small as 5 nm, enormously increasing surface area and reaction rates. The grinding works on the principle of critical speed. The critical speed can be understood as that speed after which the steel balls (which are responsible for the grinding of particles) start rotating along the direction of the cylindrical device; thus causing no further grinding.

The grinding efficiency of the one-half charge is considerably greater than for the one-third and, therefore it ca be expected that power consumption per gallon output will actually be less than with the smaller charge.

Grinding media should be periodically checked. Reduction in the quantity and size of the grinding media will result in poor grinding. We suggest a maximum schedule of once every six months, but any established procedure should be decided by individual experience. In some cases, where abrasive materials are involved, once a month is not too often and, in a few cases, even shorter intervals are indicated.

The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous non-ferrous metals. The ball mill can grind various ores and other materials either wet or dry. There are two kinds of ball mill, grate type and overfall type due to different ways of discharging material. There are many wet ball mill suitable for use in a ball mill, each material having its own specific properties and advantages. Key properties of grinding media are size, density, hardness, and composition.

Aside from common ball mills there is a second type of ball mill called Planetary Ball Mill. Planetary ball mills are smaller than common ball mills and mainly used in laboratories for grinding sample material down to very small sizes. A used ball mills consists of at least one grinding jar which is arranged eccentrically on a so-called sun wheel. The direction of movement of the sun wheel is opposite to that of the grinding jars (ratio: 1:-2 or 1:-1 or else). The grinding balls in the grinding jars are subjected to superimposed rotational movements, the so-called Coriolis forces. The difference in speeds between the balls and grinding jars produces an interaction between frictional and impact forces, which releases high dynamic energies. The interplay between these forces produces the high and very effective degree of size reduction of the planetary ball mill.

Since China joined with international standards organization since the domestic industries manufacturing level have been significantly improved, and constantly introduce foreign advanced technology, continuously expanding their own production technology and production capacity, make us China in the international manufacturing market stood in a important position, but since a long time ago the countries all over the world will know that we Chinese the most abundant mineral resources is a piece of fat meat, so after accession to the wto, foreign mining machinery manufacturer also is constantly the march of our market. Long ago China to world impression is the low level of manufacturing industry representatives, as long as it is to buy low quality, low price of machinery and electrical equipment and the first thought is China, in fact, with the progress of The Times, China is slowly to show the world his change his manufacturing level to rise.

But we native brand enterprise, in the price of dominance without today, also is stepping up after multinational company. However, compared with the multinational companies, local brand enterprise existing research and development power still show is weak, product research and development is not satisfactory. From the general situation in look, about half of the research and development organizations can't play their due role. The earliest established institute for example, its research and development personnel are now but dozens of people.

Cement plant is usually located closely either to hot spots in the market or to areas with sufficient quantities of raw materials. The aim is to keep transportation costs low. Basic constituents for cement (limestone and clay) are taken from quarries in these areas.

Cement ball mill is also named natural material mill, material grinding mill and clinker mill, is key equipment for grinding following the concrete crush process, which can be trusted in the manufacture industries, including cement, silicate, new building materials, refractory material, fertilizer, ferrous metal, nonferrous steel and glass ceramics, etc. Cement ball mill may be used for the dry and wet grinding for all kinds of ores as well as other grind-able materials. Based on different materials and discharging methods, there are dried up cement ball mill and wet ball mills for option.

Cement Manufacturing Process

1). The dry cement process consists of many simultaneous and continuous operations using some of the largest moving machinery in manufacturing. Over 5000 sensors and 50 computers allow the entire operation to be controlled by a single operator from a central control room.

2). The limestone is combined with clay, ground in a crusher and fed into the additive silos. Sand, iron and bottom ash are then combined with the limestone and clay in a carefully controlled mixture which is ground into a fine powder in a 2000 hp roller mill.

3). Next, the fine powder is heated as it passes through the Pre-Heater Tower into a large kiln, which is over half the length of a football field and 4.2 metres in diameter. In the kiln, the powder is heated to 1500 degrees Celsius. This creates a new product, called clinker, which resembles pellets about the size of marbles.

4). The clinker is combined with small amounts of gypsum processing, limestone and finely ground in a finishing mill. The mill is a large revolving cylinder containing 250 tonnes of steel balls that is driven by a 4000 hp motor. The finished cement is ground so fine that it can pass through a sieve that will hold water.

5). The cement mill process begins when limestone, the basic raw material used to make cement, is transported by rail to the Edmonton plant from the Cadomin limestone quarry 220 kilometres west of Edmonton.

Since 2000, in the domestic basic industry and infrastructure development the incomes of mining machinery products, including crusher, the sand, the market demand machine etc, gross industrial output value and sales growth speed stability in 32% 40%. The market demand in the drive mining machinery manufacturing to economic growth, promote the whole industry more progress of technology, enhance the participation in international competition ability, our country mining machinery industry in international mining project construction is playing a greater role.

Machinery industry is one of the industries that are directly related to the industrialization level of our country. At present, China has been one of the leading powers of mining machinery manufacture, but it still has a long way to go to be an industrial power. Machinery industry is the pillar industry and the promising industry that our country focuses on supporting and promoting. So as the leading industry of mining machinery, crusher industry benefits a lot. Of course, our final purpose is to carve a niche for China's machinery industry in the international market, which of course is a slow process. So the crusher enterprises should not reach for what is beyond your grasp, and should primarily gain a foothold in domestic market.

Mining machinery is the development of the modern science and technology and the overall industrial level is closely linked, especially and mechanical engineering science and mining the academic development are closely linked. Mechanical engineering science and the general trend of development will be digital, intelligent, precision, miniaturization, life and ecosystemizing. Mining machinery as mechanical engineering discipline is a branch of, also follow the general trend of development.

The manufactures that engage in mining machinery are countless, and the internal competition is also very intense. While, not all the all the product qualities are the same, so the investors should polish eyes in purchasing the equipment, and choosing the most suitable one. Basing on domestic market, crusher manufacturers should actively hunt for more home customers and focus on the areas that are relatively remote and backward, for they need building road and railways, so crusher will be greatly needed in there.

With the thorough implement of the concept of environmental protection, many technologies are applied in production, for example, in the year of 2009, hybrid power was introduced in the energy conservation study of mining machinery and developed the first new tape jaw crusher whose energy conservation ability is 30% of the traditional one, and with higher efficiency and productivity.

During the operation of mining machinery, more dust is produced, which will have a severe pollution to the environment around. Therefore, the investors should consider dust-cleaning apparatus during selecting equipments.

As we all know, the cement is calcined at high temperature by the mixture of limestone and clay. In the cement production process, the first problem is crushing limestone. After many trials, transformation, developed various types jaw crusher which are classified into the coarse crushing and fine crushing jaw crusher. And the jaw crusher currently has been the most widely used crushing machinery.

Jaw crusher belongs to the deep cavity crushing equipment with long crushing stroke, which is good for material crushing and crushing process can be accomplished at once. And the size of the feeding particle can be 125mm ~ 1020mm. Jaw crusher can crush materials with a compression strength no more than 320Mpa, and it has a greater yield compared with similar products. The crushing method of jaw crusher is curved extrusion, the motor drives the belt and pulleys to make the jaw plate move up and down through the eccentric shaft. when the dynamic jaw rise, angle between the elbow plate and the dynamic jaw becomes larger, thus promoting the dynamic jaw plate close to the static jaw plate, and at the same time the limestone is extruded, rubbed, ground to achieve the crushing effect; when the dynamic jaw move down, the angle of toggle plate and the static jaw will become smaller, the static jaw plate will be far from the dynamic jaw plate at the function of the rod and the spring, at which time the crushed limestone will discharge from the mouth under the crushing chamber. And realize the volume production of the limestone along with the continuous rotation of the motor crusher periodic crushing and discharging. After many tests and improvements, jaw crusher break the crushing mode of hammer crusher which crush materials by directly impacting with the hammer of hammer crusher . And realize the aim of reducing the energy consumption.

The jaw crusher is mainly used as the the first crushing process of the crushing production line, it can be used alone as well as be used assembled with other crushing machinery. This series of jaw crusher has a obviouseconomic benefit in the installation and application of cement production line. Especially used in cement production line for limestone crushing, the jaw crusher has been song highly praise by cement users.

Henan Hongxing always stick to the entrepreneur idea that business reputation comes first, and we still carry out the service purpose of customer satisfaction and follow the business principle of “quality is the most important and our customers are God”, for this reason, Hongxing Brand mining equipment frequently is exported to the_middle East, South Africa and the Southeast Asia and is well received by customers.

Driving method of domestic over ball mill:

(1) It is driven by synchronous motor; Large-type adopts low-speed synchronous motor to directly drive the small pinion of ball grinder, and the small pinion will propel the big geared ring to make the ball machine rotate. Its advantages are of high transmission rate, low coverage size, easy maintenance and improved power grid rate coefficient, but the most is pretty expensive and needs direct electricity current.

(2) It is driven by asynchronous dynamo pinion speed lower sand maker machine. As for large and_middle sized ball grinder, it will adopt asynchronous driving method. The pinion speed lower machine drives the small pinion and big geared ring to rotate the whole equipment. Its_characteristics are that it cost less, but a whole complete set of big-size speed slower equipment is necessary.

(3) By asynchronous machine triangle belt. Small sized device uses asynchronous machine to put the tooth tyre in motion by way of triangle belt, but it has such disadvantages as low transportation capacity, big coverage size and complicated repair.

For foreign equipment:

They are mainly using the following three methods:

Firstly by way of little bit sized tooth tyre and big tooth ring; secondly central promotional mode, that is to say, the motor drives the prolongation part of the hollow shaft neck by way of the speed lower, and the last but not the least, the rotator is directly installed onto the prolongation part of the barrel or the hollow shaft neck, the determinant is fixed onto the ground, thus forming a so-called “gearless promotion”. For the time being, the hammer crusher machine adopts super low speed synchronous motor whose rotating speed is just the same as the whole equipment so that it is suitable for devices with rate more than seventy-five hundred kw.

Too often, teams are formed merely by gathering some people together and then hoping that those people somehow find a way to work together. Teams are most effective when carefully designed. For this reason, on 8th April 2010, a vibrant spring day, Henan Hongxing Mining Machinery CO.,Ltd organized an internal training activity. In the multi-purpose function room of company headquarter located in Zhengzhou city, the trainees from all departments learned attentively, discussed with each other and studied from each other. We tried our best to combine listening and learning, integrate study and application.

As an old saying goes, 'The whole year's work depends on a good start in spring.' So always plan your year in spring and your day at dawn.

The term 'reporting to one boss' can be a misleading one. In a well-designed organisational structure, people reporting to one boss do often form a team. But reporting lines are frequently designed within the constraints of grading structures. Of necessity, there is often a compromise between the need for traditional reporting lines, and grouping people together who are a team. In reality, team structures are often complicated, and people can be members of several teams, because a team is a group of people working together towards a common goal. So we give a complete training class about our product such as ball mill and other China professional jaw crusher.

As much as possible, include input from other members of the organization when designing and wording these goals. Goals might be, for example, “to produce a project report that includes a project plan, schedule and budget to develop and test a complete employee performance management system within the next year.” Write these goals down for eventual communication to and discussion with all team members.

The employees collaborated with each other and learned relevant knowledge hard. Through the training, all the staff not only improved their own skills and their understanding of company administration system but also had a deeper comprehension of us Hongxing Machinery’s policy that surviving on quality hammer crusher machine and developing through science and technology and company philosophy that virtue comes ahead of business and profit comes after customers.

Throughout the 25 years’ development, Hongxing Machinery has hold to the staff training plan of cultivating ordinary staff into outstanding talents. The achievements, experience and lessons gained in in the process of company progression themselves would be great training material for us. In future training we will work harder to make every staff gain greater improvement in daily work. We have the faith that in the positive atmosphere we RedStar people are sure to build a world of our own and create new splendors.

We are in the belief of 'Unity is strength'. Baxia for our bright future!

At any times, there are unique features in the development of one thing. For business circles, the characters are more and more complex. Next, let's analyse the main features of the development of Machinery Industry.

1: The basic station

The developed countries pay much attention to the development of equipment manufacture industry, which is in the top place of the proportion, accumulation, employment and contribution and provide the important material base for the new technology, development of new products and manufacture for the equipment manufacture industry, so it is the indispensable strategic industry of the modern economy. Even the industrialized countries entering information society all pay much attention to the development of machine manufacture industry.

2: Scale economy

The globalization manufacture has become the developing mainstream of the transnational companies. At the same time of regrouping and competition expansion, the big enterprises strengthen the investment and development for the operation to increase whose set capacity of system, individuation and diversification to adapt the market.

3: Imbalanced development

Taking 2003 as an example, 99% of top 500 enterprises are from North America, Asia and Europe, which shows that the three continents are in the incomparable governing place in the industry of world machine.

4: Deepening structure adjustment and change in the manufacture mode and management mode

The developed countries strengthen the industry transfer and the machine products with low adding value are arranged to be manufactured in the developing countries with potential requirements. To meet the change of market requirement, big manufacturers adopt professional manufacture and single product with large quantity becomes the new characteristic of the manufacture mode among top 500 enterprises and at the same time, the traditional manufacture mode is changing to the customer-oriented. The individuation of service is the main factor for the competition.

5: The new change of the mode in the industry of machine manufacture

There are two kinds of traditional globalizations: one is to regard own country as the manufacture base and sell products to other countries and the other is to invest and build manufacture base in other countries and manufacture there and sell products to own country or other countries. The characteristics are: to own the manufacture facilities and technology and manufacture products by self and for using the resources, only to use the raw materials, personnel and fun from host countries.

With the development of information technology, the management mode changed fundamentally and the organization mode changed accordingly. These changes happened in the transnational companies and will keep on developing as a new mode of globalization. The characteristic of this change is to widely use other countries’ manufacture facilities and technology strength to manufacture products and sell to all over the world. The companies of machine manufacture industry set up processing network of parts all over the world and take charge of the installation and marketing of the products. The preparation of raw material and globalization of parts become the developing trend for the world machine manufacture industry.

6: The transnational purchase in the machine manufacture industry is intense

The modern purchase doesn’t only lay emphasis on the competition and association of strong companies is the main method to gain competitive advantages, which is the big character for the machine manufacture industry to gain development. Now the market competition is intense and invest for building factory is in big risk, so many enterprises choose the combination and purchase. On the premise of building factory, to optimize the product structure to increase throughput, expand market share and gain scale efficiency is the best way. The industries with high technology have the threat from technology innovation, so only by the association, can enterprises become stronger. The strategic purchase in the machine manufacture industry leads to the new deployment of the resources and the cooperative situation of the competition appears.

7: Products with high technology

The development of modern science and technology with the information technology puts forward higher and new requirements for the machine manufacture industry. All the countries and areas and especially the developed countries lay emphasis on the development of machine manufacture, which shows that as the high and new industry, the machine manufacture industry plays an important and indispensable role in promoting the social technology progress and industry upgrade. The fast development of the high and new technology plays the role of driving, upgrade and alternation. The achievements of high and new technology, such as information equipment technology, industry automatization technology, digital-control process technology, robot technology, advanced electricity technology, electron and electric power technology, new material technology and environmental protection technology are widely used in the machine industry and the technology content is the key for the market competition.

At present, our country magnetic separation machinery manufacturer a lot, to make the product variety, specifications complex, the classification methods are also different. Although various magnetic separation machine has a different program difference, but according to the magnetic YangJiang degree, produce a magnetic field method, structure, choose different role don't, magnetic separation machine into a variety. Magnetic separator machine is use of various minerals than the coefficient of different magnetization, and by the magnetic mechanical force will magnetic mineral and the magnetic mineral separated machinery.

In the 1950 s in China only weak magnetic field magnetic separation machine belt type and tube type electromagnetic magnetic separation machine. Until 1965, just from Sweden Sarah company introduces the cavitation permanent magnet magnetic separation machine, and counterfeit, because it save electricity and magnetic induction high strength, simple structure, low cost, easy operation and maintenance, machine quality is light, cover an area of an area small, processing capacity, so fast in China in application, all replaced the electromagnetic magnetic separation machine. At present, our country magnetite concentrator use wet weak magnetic field intensity magnetic separation machine are permanent magnet tube type magnetic separation machine, using magnetic pulley and magnetic force to take off the cistern, also is the permanent magnet, realized the weak magnetic field of magnetic separation equipment and magnetized. By the 1980 s, permanent magnetic separation machine and get the cavitation fast development, not only the specifications varieties, and to the large-scale development, up to 1500 mm in diameter, tube has reached 4000 mm long, and on the structure and do improvement. At the same time, start to take new high performance materials of rare earth permanent magnet nd-fe-b magnetic materials, improve the magnetic induction strength, improve equipment performance, expanded the scope of application, in recent years, its application to obtain the further promotion, not only use it in manufacturing field magnetic separation machine, and successfully developed several strong magnetic field intensity magnetic separation machine.

The magnetic separation equipment level of technology has advanced international level, some already meets or exceeds international advanced level, in short in the world is advanced. Now in addition to the superconducting magnetic separation equipment, China's development, production of magnetic separation equipment has a leading position in the world.

In selecting a magnetic separation equipment, mainly is based on magnetic minerals and feed size to determine, such as strong magnetic minerals: grain size of 10-360 mm, choose magnetic pulley; Grain size of 6-0 mm, choose permanent magnet type magnetic separation machine; Weak magnetic minerals; Grain size of 7 to 14 mm, selection of roller of strong magnetic separation machine; Grain size in order to 5 mm, but according to ore properties choose ring type, roller type or disc strong magnetic separation machine; Grain size of 0.15 mm, can choose the high gradient magnetic separation machine.

There is something very basic about manufacturing – value is added by taking raw materials and labor, and producing products that can be sold in high quantities, with quality, to generate good return on the investment.

The manufacturing sector remains significant in leading economies worldwide, but faces major issues such as cost competitiveness, product innovation and how to compete in an increasingly global market. That people live and work in peace and contentment can not be realized without a country’s prosperity, a nation’s prosperity and people’s strength can not come true without economic development and economic advancement can not go without development of science and technology, and it will promotes macroeconomic development through penetration and influence of production factors. As we all know that productivity includes labor means, labor object and worker which are all indispensible.

Of course, innovative design and product development are important to generate competitive advantage. But design and development can be done in locations that are not necessarily tied to the production plant. Intel, for example, builds semiconductor fabrication plants in many different worldwide locations. Likewise, many automation companies build products wherever it suits their business needs. Hongxing Machinery as the leading manufacturer of jaw crusher and China professional sand maker will certainly not lose its stand.

During the past decade or so, it seems clear that manufacturing is tending to migrate away from the U.S. for a variety of factors, not the least being that manufacturing appears to have a negative image. PLC inventor, technology guru and author Dick Morley suggests that the idea that manufacturing rotary kiln is somehow bad has caused jobs to be driven out. He suggests that no community in North America really wants a new assembly plant, a printed board facility or a semiconductor enterprise. In television dramas the villain is the businessman, and the hero is the scrubby squatter who fights to prevent progress.

In modern economy, with the incessant growth of economic level, more and more industries develop into groups, among which metallurgy, machinery processing business, coal crushing and sand maker, chemistry and mining industry significantly drive the adjustment of industrial structure. So science and technology is the sufficient and necessary condition of economic development and economic improvement will not be possible without it.

In a recent survey of Chinese and U.S. manufacturers by Industry Week, 54% of Chinese companies cited innovation as one of their top objectives, while only 26% of U.S. respondents did. Chinese companies spend more on worker training and enterprise-management software. And 91% of U.S. plants are more than a decade old, vs. 54% in China.

At present, the Chinese government holds about 10% of outstanding U.S. Treasury securities, second only to Japan. Most people feel that the Yuan is undervalued by about 30% and a revaluation will devalue China's U.S. debt by a third. Unless it simply accepts a devaluation of this huge debt, China will surely be using this cash to do a lot more deals in the U.S.

As we all know, crushing of material is a technical process that is widely used in the industry departments like metallurgy, mining, construction, chemistry, electricity and road construction. Through many years’s practice and conclusion and the purpose principle of crushing and grinding, it shows that strengthening the crushing and trying to decreasing the feeding size is the important method of improving the grinding efficiency and reducing the ore dressing cost. For this reason, reducing the cost and increasing economic profit is the starting point and the crusher has been developing in the direction of fine breaking and high efficiency and low energy consumption. In addition, with the constant development of science and technology, the size of mining exploitation is becoming larger and larger and the breaker is also developing more and more large-sized.

As an old saying goes, “first-class enterprise focus on brand, second-class on market, and third-class on product”. Quality brand can bring good public praise in the industry. In recent years, brand awareness of Chinese engineering machinery users has been improving sharply. So when a brand is accepted by the customers and printed into their heart, then its place is difficult to be superseded. As for mining equipment band, in order to take up the market, it firstly should take up some place in the heart of the customers, and one key is band improvement. The existing commonly-used crushers include impact crusher and cone crusher.

We can see from the above two phenomena, if a company wants to enjoy popular support, he should firstly analyze the client’s need and find the product development direction and secondly should improve product and service quality and build his own independent band. Building a branding is building the image of the enterprise and make this image take root in users’heart. In this way, when the competition becomes fierce, the big band that is accepted by the users will survive even without fighting.

The superficial sales is just simply selling several products, but the high level of selling is to promote his own brand. Only by popularizing his own brand can he win over ceaseless clients.

Hongxing Machinery is just a kind of such mining machinery company that regards quality as life and has built internationally famous brand like ore benefication machine. Here in our company, the customers are the God, and we always follow the quality principle that we hold responsible for every production process and for every client. Everything that we are now doing is for your consideration because we are deeply convinced that quality is the gold key to market.

According to the industry policy that our country will give significant support to the development of basic industry like energy, transportation and raw material, as the backbone of these basic industries, mining machinery should get prior support so that it can further develop and improve in order to provide more crushing and grinding machines with international advanced level for the exploitation of coal, metal and non-metal mining hill, and satisfy the demand of energy and raw material of national economic development. The mining equipment mainly includes jaw crusher, sand maker and powder-grinding machine, among which crusher is the most important link in the whole rock crushing process and also the important symbol of measuring the strength of the mining facilities manufacturing industry.

Mining breaking and grinding machinery is devices that have high technology content and integration and the development of new equipment is mixed together with more and more achievements from other business scopes. With the development and advancement of material science, information technology and computer technology, every round of products are injected with new techniques, the update cycle of spare part is becoming shorter and shorter and the upgrading of new equipment is becoming faster and faster. Especially for the development of large-sized mining equipment, because there is no mature experience that can be learned and any mistake is allowed, it has to be researched with the help of mixing with many discipline techniques, improve the design efficiency and quality and enhance the company’s independent innovation ability and market competitiveness. The rock crushing and grinding devices has formed a trend of digital development with the basis of computer and internet technology.

When we look back on the development history of crusher, we can conclude that the main breakers are vertical impact crusher, hammer breaker and so on. Since the types are too many, their names are different.

The impact crushing machine developed by Henan Hongxing Mining Machinery is the example that perfectly combined with professional breaking technology and engineering manufacture and also the sufficient representation of new technique and processing method. It not only can provide the best rock aggregate for the highway, railway, high building, municipal works, hydroelectric dam construction, port and wharf and concrete mixing station, but becomes the core equipment in the artificial sand making industry and stone transformation scope, and more and more becomes the mainstream machine in the business scope of metal rock breaking, quartz sand production and slag disposal. So this series of products are well received by customers from home and abroad at the same time.

Conveyor, also named as transmitter, is a rubber and fiber and metal combination product that is used for loading and conveying materials. It is widely applied for transporting various kinds of solid material and powder materials. Conveyor can continuous, high efficiency, big obliquity transportation, and the safe operation, easy to use, easy maintenance, low freight and shortened the distance transportation, reduce the construction cost, save manpower. The daily use of the more is to pay attention to press a regulation strictly operation, and the daily maintenance are mainly used for the protection of the environment and the hardware to prevent the destruction of the system software. Programmable logic controller is functions of the logic control. It will come from all kinds of sports and function of the conveyor instruction in logical order, so they can accurately, coordination and orderly safety operation. In the meantime, it can send many kinds of information from the tools and working state to the transmitter and timely and exactly give further control order, in which way the control of the whole belt conveyor can be realized.

Speed by container in central usually main shaft and the speed of the motor machine to complete. It will motor speed matching into actual voltage value back to servo drive system as speed feedback signal, and instruction speed compared voltage value, so as to realize the precise control of the speed. Zhengzhou red star machinery factory specializing in the production of drum dryer, sand the dryer, drum dryer, sand drying apparatus mine machine equipment, the company relies on a strong research and development and production strength, has become one of the few domestic crushing, system of mechanical sand export base. Here should pay attention to the non-timing feedback voltage matching connection, and do not remove speed measuring machine. The cause of the speed control are due at the non-timing feedback line or break line be caused by. The central position of the earlier machine tool use linear or circular synchronous sensors or rotating transformer, and modern machine tools themselves

With grating feet and digital pulse coder as position central components, they coordinate transformation of machine tool in the operation of the actual position directly or indirectly central, will be the central values to Henan vibrating screen and feedback with instruction compared to coordinate the displacement until instruction position, so as to achieve precise control of the position. Position loop possible fault for more hardware failure, such as position central components to be contaminated, wire connection problem and so on.

At present, there are more than forty companies that are manufacturing vertical drying machine. When choosing such a device, many customers only pay attention to its superior characteristics but not give attention to its limits, because any kind of machinery has it own application scope but nor all-purpose applicable. For this reason, many problems occurred in its using process, and to make things worse, some equipment is idled even after using for several months.

1. First problem is very common, that is when purchasing, and the specifications of the dyer machine is too small. In a cement plant in Sichuan Province, the company purchased from a manufacturer, the production company said that the production capacity can reach twenty tons every hour, but in actual use, the output ability is only fifteen tons for each hour. When we look into the reasons, we find that the manufacturing enterprise purposely decrease the specifications with the view of successfully doing the business with low prices which in the end brings loss to the using corporation.

2. Material baking is not stem, yield of not to come. Material baking not stem, in drying slag moisture content is lesser, the effect is good, if baked some, such as clay, fly ash, etc material especially prominent. A cement plant in Yunnan choose a company a φ 2.2 * 14 in the purchase, production manufacturer when baked clay speak up to 15 tons /, the actual production of only 5 tons /, the contrast is bigger. Investigate its reason:

(1) moisture content really is on the high side, stay time enough;

(2) the drying system equipment is not reasonable, can not be education moisture;

(3) manufacturers can't master good drying original parameters.

PF series impact crusher is widely used in various metallic and nonmetallic ores, cement, abrasive material, glass, construction material, machine-made sand, metallurgy, etc. Impact crusher is also applicable to crush various stones with different hardness in medium and fine crushing area, such as used in iron ore crushing plant, non ferrous metal, emery, bauxite, quartz sand, basalt, etc. PF series impact crusher for sale is usually used in secondary crushing processing, subsequent the primary crusher-jaw crusher.

Since ground minerals are the major raw-materials used in various items like ceramic industries, Chemical, Metallurgical industries etc, the industrial demand of these products is ever increasing all over the country. Despite the fact that there are many registered and non-registered units operating in the country, there is enough scope to later the need of industrial sector. Reportedly, these are so many supplier’s traders and agents who supply the ground minerals to the existing industries from outside the state. Hence a stiff market competition in this sector is never ruled out. But maintenance of customer’s specification to their satisfaction uniform quality, supply schedules and payment terms are the key to open vast marketing opportunities for new unit in this field.

In mine machinery,Many criteria need to be considered in selecting the appropriate equipment for a particular mining operation. The most important factors to consider are safety, strength and durability, though cost can be a major aspect.

There is a vast range of mining equipment available, dependent on the application for which it is to be used. Underground mining, surface mining and open pit mining all require the initial movement of large quantities of earth. This equipment is similar to that used in large building projects, in the form of dump or haul trucks, diggers or shovels, back hoes and cranes. The extraction of ore requires a different collection of mining apparatus. Ore crushers, explosives, separators and other devices complete the full complement of necessary mining equipment. It is vital to remember that personnel are the fundamental aspect of any mining operation and their safety is paramount. Essential mining equipment must also include safety supplies, such as hard hats, ear defenders and respirators, to prevent employees form injuring themselves (or each other) whilst working in hazardous conditions.

Heavy duty earth moving equipment can be bought direct from specialist manufacturers who focus on loaders, trucks, drills and scrapers. Other companies offer leased rebuilt / used mining equipment by major manufacturers. Many mining equipment manufacturers make ore extraction equipment. Some specialise in air compressors concentrators and tunnel boring machines, whist others produce conveyors, crushing plants and hoppers. Specialist underground mining equipment manufacturers offer an extensive range of pallet handles, tow tractors, belt drives, radial stackers and power packs. Several manufacturers produce a range of health and safety products. Some specialise in respirators, hearing protection, gas detectors, fall protection devices, hard hats and goggles, while others offer an assortment of specialised flags and lights for use inside mines, along with rescue equipment for both underground and surface mines.

A mining undertaking can often be large and complex. In order to ensure a project progresses efficiently, safely and is completed in a timely fashion, sufficient supplies and equipment must be made constantly available. For speedy service and extensive choice of products, the Internet is an excellent choice for the purchase of mining equipment. Many mining equipment manufacturers and distributors have detailed specifications and photos of their inventory on their websites and there should be few problems in locating the appropriate tools and equipment for any mining project. New equipment can be bought directly from its manufacturer, though it can be a good money saving exercise to peruse the used and / or refurbished equipment offered by many manufacturers. Other firms specialise in the hire of mining equipment and dependent on the available capital, this may be a preferable option to outright purchase.

A shortage of qualified workers for the mining industry has the Iron Mining Association of Minnesota worried.

Duluth, MN - (Northland's NewsCenter) - The growing Northland mining industry, in conjunction with an impending flurry of baby boomer retirements, is creating a significant worker shortage.

Industry spokespeople say they're concerned about the Range finding the thousands of qualified technical workers it's expected to need over the next few years.

'Almost 40-percent of the people working in the mines can retire at this time...so we actually have a work force shortage,' says President of the Iron Mining Association of Minnesota, Craig Pagel.

One of the biggest problems is finding enough qualified applicants for the positions.

'You might find one out of 40 qualified. You might have a couple of job openings and over 400-people will apply and it gets weeded out pretty quickly because they do not one have the job set skills that they need, they might not have the education that they need,' Pagel says.

As the mining industry evolves on the Iron Range, employers are demanding more from job candidates.

'They're really struggling to find hundreds of people that have very specialized training,' says Regional Labor Analyst for DEED, Drew Digby.

Years ago a high school graduate could get a job working in the mines...but not these days.

Currently a qualified mine worker needs to have at minimum of a two year degree.

'What we're finding is, many cannot pass an 8Th grade reading comprehension, they can't pass 8Th grade math skills sets...but more importantly is attitude and the fact that many of them cannot pass the background checks and drug tests...it's a real concern,' Pagel said.

'One of the things you keep hearing from the mines is they want someone who has all those great, old school technical abilities, they ability to work with things and get your hands dirty, but also handle really specialized equipment...some things with a lot of computer assistance,' Digby says.

The Iron Mining Association has been working with the Northeast Minnesota higher education and state lawmakers to develop curriculum's for high school juniors and seniors so they can get college credit even before going to university and have a better understanding of what's needed to be a modern mine worker.

'These are very good paying jobs. Some of the starting salary jobs in the mine's, on an hourly type of job is 26-dollars an hour, plus benefits,' Pagel said.

An attractive annual salary of around 54-thousand dollars a year.

Pagel said there are about 175 service sectors that belong to the IMA, along with the mines, that supply products and services on a daily basis, who are also concerned about the lack of a qualified workforce.

Minister of Land and Resources recently held China International mining Conference, said China is committed to scientific development, continue to adhere to save low resources consumption, little environmental pollution and the new road to industrialization. 'scientific development, promote green mining' is a new path of industrialization in China mineral resources in the field of concrete embodiment. Here, the green mining industry has become the most eye-catching words, the reason for it visible, because it is China's economic development, because it is in line with the direction that mining industry calls for the requirements of energy conservation advocacy and environmental protection development.

The so-called 'green mining' refers to the disturbance in the mine environment is less than the premise of the capacity of the regional environment to achieve optimal exploitation of mineral resources and the environment are minimized. Implementation of green mining industry there are three stages: First, the regional environment through the development of capacity or former capacity evaluation and mine environmental assessment and disturbance, the establishment of environmental evaluation index system and technical standards, to develop green mining plan; but through technological innovation, optimize Process, to achieve mining, dressing, smelting and refining process, a small disturbance, no poison and less pollution; Third, through the mining environmental management and ecological restoration, to achieve minimum environmental disturbance and ecological reconstruction optimization. We say that the development of green mining is the voice of the times, China's economic development, it is not groundless, but evidence-based. Over the years, our economy has been growing rapidly though, but we also paid a high price, called a lot of fees. Relevant data show that the country due to ground subsidence due to mining to 180 locations with more than 1,600 pit collapse, subsidence area of over 1150 square kilometers. The collapse of the national mining subsidence disaster occurred nearly 40 cities, causing serious damage to the 25 annual ground subsidence due to mining, the loss occurred up to 4 billion. The mining, ore mining 6 billion tons per year the amount of disturbance of the Earth's environment, induced the mountain crack, collapse, landslide, debris flow, earthquake and other geological disasters. These figures are shocking, but in order to change this situation, to promote green mining industry is the best way.
