Slag is a byproduct of metal smelting, and hundreds of tons of it are produced every year all over the world in the process of refining metals and making alloys. Like other industrial byproducts, slag actually has many uses, and rarely goes to waste. Slag appears in concrete, aggregate road materials, as ballast, and is sometimes used as a component of phosphate fertilizer. It might often be regarded as to become a combination of metal oxides and silicon dioxide.

Common components of slag include the oxides of silicon, aluminum, and magnesium, as well as sulfur, which is always present. Slag also contains phosphorous, calcium, ash, remnants of flux materials such as limestone, and remainders of chemical reactions between the metal and the furnace lining.

Slag is produced during the smelting process in several ways. Firstly, slag represents undesired impurities in the metals being smelted, which float to the top during the smelting process. Secondly, metals start to oxidize as they are smelted, and slag forms a protective crust of oxides on the top of the metal being smelted, protecting the liquid metal underneath. When the metal is smelted to satisfaction, the slag is skimmed from the top and disposed of in a slag heap to age. Aging slag is an important part of the process, as it needs to be exposed to the weather and allowed to break down slightly before it can be used.

In slag crushing process, there are many euqipment used, like jaw crusher, slag crusher, grinding mill, belt conveyor. Zhengzhou Hongxing is the popular manufacturer of all types of crushers including slag crushers in China together with grinding mills and other mining facilities. At present, our slag crushers have been sold and exported at home and abroad. For all clients, Hongxing can provide high-quality services and low quotations.

For all heavy industries, machinery and construction equipment are important in the construction and product projects. As is known to all, mining industry is the core industry in national economy and plays a very important role in China economic construction and social development. Naturally, mining equipment is also vital for mining industry. Mining machinery is used for extraction of minerals and rich selection of mechanical and other operations, mainly including exploration machinery, ore mining machinery and mineral processing machinery.

There are plenty types of mining machines in mining equipments industry. For domestic industry, it has already several mature equipments, such as exploiting equipments, mineral specification equipments, crushing equipments, grinding machines, sand making machines, sand washing machines, screening machines, mineral heading assembly, mineral loading equipments and optional equipments, etc.

Exploration machinery is mining euqipments used in the pit and drilling prospecting operations. It’s a kind of mining machinery. Pitting is excavating certain area of tunnel in deep accumulate, loose rock ore mining or , in order to understand the geological condition before mining operation. Mining machinery includes ore mining machinery and mineral processing machinery. The first mining equipment is mainly used for metal ores and nonmetal ores. By ore dressing process the processing machinery can be divided into crushing machines, grinding machines, screening machines, sorting (the sorting) machinery and mechanical dehydration.

Directing at some mining equipments company in mining market, they are on a small scale, large numbers and distributed widely with inefficient management and result in excess production capacity in domestic mining equipment industry. If things go on like this, Not only these companies can't live long but also would troubles get brought to our mining equipment industry. As China government turn energy saving and emission reduction on, weeding out low capacity will be sooner or later.

At present, because of serious environment polution, all governments advocate 'green industry' 'environmental protection'. For responding the calls, Chinese mining industry companies start various methods to make innovations, such as tailings recovery, energy recycling, new machines development for less polution such as mobile crushing station, ultra-fine grinder. With the trend, the competitives in the industry are more and more fierce.

The main products are newly-designed sand making machine, vertical shaft impact crusher, compound cone crusher, impact crusher, jaw crusher, high pressure grinding mill, vibrating feeder, vibrating screen, belt conveyor and sand washing machine, etc. Henan Hongxing Machinery Co., Ltd., the famous compay in China, has formed a complete production-chain that takes crushers and mills as the main products and vibrating screen, vibrating feeder, etc. as supplementary products.

Todays, prices of mineras ore and petroleum are in large fluctuation. And the situation is obvious.

Mining and petroleum industry are the two main industry all over the world. If one of them changes, it must affect global economy in some degree. Let's learn about the stake from research and development of the Research & Development Corporation of Newfoundland and Labrador (RDC).

'Leading-edge geoscience R&D plays a critical role in supporting mineral and petroleum exploration and development,' said the Honourable Susan Sullivan, Minister of Innovation, Trade and Rural Development. 'As Newfoundland and Labrador's mining industry continues to grow, research and development will assist in greater exploration and development. These investments, through the Research & Development Corporation, mark a positive step in increasing the potential to develop new mines and invite new high value business and technology development opportunities for Newfoundlanders and Labradorians.'

Mining is the second largest industry in Newfoundland and Labrador, employing more than 4,900 people in rural areas of the province, while oil production represents almost 27.5 per cent of Newfoundland and Labrador's nominal gross domestic product. The total value of minerals and petroleum production in 2010 was $12 billion.

'Newfoundland and Labrador is home to rich mineral resources, which offer students, faculty and industry partners tremendous opportunities to explore and discover,' said Dr. Christopher Loomis, Vice-President (Research), Memorial University of Newfoundland. 'This funding will build on Memorial's world-class expertise in geosciences and also help us forge stronger relationships with the mining and petroleum industries.'

The phenomenon appears not only for RDC, and it's appliable for China. At present, with the rising price of iron ore, China crusher industry and even the whole mining machinery industry have a great attack. Jaw crusher, impact crusher, mobile crushing plant are adjusted on prices, technologies, structures and services.

With the situation of continous technology innovations, some enterprises with strong competitive sense have aimed at domestic advanced consumers and matched product accessories. Just as the same as the situation in other countries, crushers were used in many industrial field, such as chemical industry, mining, construction, irragation works,metallurgy,coal mining, glass making etc in china and the most important applying field is cement producing, road paving and Mining, this application covers about thirty percents of the whole application of crushers.

At present, our crusher manufacturing industry has been in the rank of international production countries, and the comprehensive competence and development motivation of mining machinery industry are getting close to developed countries.

the life of the crushers itself is a problem(it seems that just for the buyer of crusher,the life of crushers is a problem,but the fact is for both seller and buyer,we hope our crushers get a life as long as possible).generally, a smaller crusher has just three to five year life,so,every five years later,we need update(or we can say buy a new one,it depends how you maintain your crushers)our crushers,the survey tells us a truth that twenty percent of crushers in china need to be updated every year,and the survey also reveals that many crushers have been used over their life-time anticipation.so,every year,the crusher market will get a wave of updates,that’s the second reason .

When the export of a product increase fourty to seventy percent,we call it a booming period of the product,then it runs into a critical period with trade friction appearing,that’s where chinese crusher producers stand in.so,we should remind our enterprises that we should keep ourselves alert on the probable trade friction.

Chinese crusher production scale has been in the top list of the world,but we still get a lot to learn,and as the increase of the export of crushers,chinese crusher producers will have face many contesters from all over the world,they still get a long way to go.

Appearance of hydraulic cone crusher and mobile crushing plant make a solid foundation for China crushers stepping into international market. The mark of 'Made in China' is outstanding at home and abroad.

Environmental issues received increasing attention during the last three decades of the 20th century, a situation that no doubt will continue as we move into the 21st century. Many rare mineral ore is disappearing with cities' rubbish. Human research and develop new technologies which is the main reason to lead rare mineral reserves down.

Reported by 'New Scientists', mineral resources is the same with petroleum, and both are renewable. There is a question 'how long do mineral resouces last to be exploited?'

Because the processes that form ores operate on geologic time scales, the most economic mineral resources are essentially nonrenewable.New deposits cannot be generated in human timescales.But, as mentioned previously, as the reserves of materials become depleted it is possible to find other sources that are more costly to exploit.Furthermore, mineral resources are not evenly distributed. Some countries are mineral-rich; some are mineral-poor. This is a particular issue for strategic mineral resources.

How long current mineral resources will last depends on consumption rates and reserve amounts. Some mineral resources will run out soon, for example global resources of Pb, Zn, and Au? will likely run out in about 30 years. U.S. resources of Pt, Ni, Co, Mn, Cr less than 1 year. Thus, continued use of scarce minerals will require discovery of new sources, increase in price to make hard-to-obtain sources more profitable, increased efficiency, conservation, or recycling, substitution of new materials, or doing without.

In order to help solve this crisis, China government propose 'sustainable development''green energy'. Almost enterprises are trying to change into 'green enterprise'. Hongxing manufacture mobile crushing station, slag crusher, tailings recovery, ultra-fine Raymond mill to save the materials and reduce the polution.

Dewatering is the removal of water from solid material or soil. Mineral dewatering is the removal of water from minerals.

Generally speaking, the ore concentrates classified have some moisture.

A. In the sandstone production line. Because in the line, many ores must be washed or classified, the final ores necessarily include more or less moisture.

B. In the ore dressing line. Whatever flotation process or magnetic process, they both is related with water:

(a)For flotation process (flotation machine), it's obvious. The water weight in ore concentrates of flotation plant is 4~5 times compared with the solid weight.

(b)Magnetic beneficiation (magnetic separator) can be divided into dry and wet ways. So, the water exists in wet beneficiation.

The reasons for mineral dehydration.

A. Transportation. If ore concentrates aren't dewatered, it will be difficult and high-cost.

B. In cold regions, ore concentrates with great moisture shows freezing phenomenon, which isn't helpful for ore concentrates transportation.

C. Not only dewatering for ore concentrates, but also for tailings. The moisture in tailings is almost above 70%. Therefore the tailings dehydration is necessary before entering into tailing warehouse.

Mineral beneficiation is a process by which valuable constituents of an ore are concentrated by means of a physical separation process. As one of the initial steps of extractive metallurgy, the main purpose is to prepare the ore prior to downstream purification processes. The most common mineral beneficiation processes include: sample preparation, comminution, size classification, and concentration.

Recent years, China has great changes and innovations in various industries. Mineral beneficiation equipment brings and adopts advanced technologies from foreign enterprises: permanent magnetic separator, spiral classifier, spiral chute.

Sign the new technology from benefits of thermal coal beneficiation.

a. Saving in transportation cost by not transporting the dirt material over long distances.

b. Saving in capital and operating cost of power plants.

c. Cost of energy produced using washed coal may also reduce further provided the washed coal helps in increasing PLF and washery rejects are utilizedefficiently in higher capacity AFBC/CFBC boilers.

d. Regulating the quality of coal feed

e. Reduce the ash content resulting in improving the life of the pressure parts of the boilers, grinding parts of mill, pulverized coal pipe lines, coal burner nozzles, ducts, ESP internals, air pre-heater seals, ID fan impellers etc.

f. Specific secondary oil consumption is also expected to reduce.

For beneficiation, as we know, flotation beneficiation and magnetic beneficiation are used widely. In the two ways, flotation machine, magnetic separator, spiral classifier, spiral chute are the important equipment. There are another way: gravity concentration.

Gravity Concentration, one of the oldest mineral beneficiation processes, has evolved over the decades and continues to play an important role in modern mineral processing operations.

Gravity concentration, where applicable and effective, has the lowest installed and operating costs when compared with other beneficiation technologies. It also tends to have the lowest environmental impact as gravity concentration does not require the use of chemicals and reagents. Hence, with the recent increases in energy, capital and operating costs as well as environmental concerns, gravity is often one of the first processes evaluated for new flowsheets.

In the case of gold and other precious metals, modern gravity concentration equipment can easily generate saleable concentrates and provide quick cash flow at a relatively small capital cost.

Finally, gravity concentration provides the versatility for treating a wide particle size range. Using pre-concentration as an example, devices such as jigs and spirals can be used for coarser particle size classes while proven enhanced gravity concentrators can be used for scavenging fine particles. Modern centrifugal concentrators are routinely effective down to 20 microns. Good performance to below 10 Microns has been demonstrated in some cases.

Jaw crusher-hydraulic type jaw crusher is used through the hydraulic adjusting device adjust piston kind of fuel oil pump trip, based on effective hydraulic system trace quantity of oil leakage automatic regulation size oil, work cylinder injection with bolts restrictions limit elongation, overcome the job of hydraulic system dynamic jaw of hydraulic pulse, facilitate row ore mouth regulation.

Jaw crusher is the common equipment in every mining production process. As the equipment, there are some parts easy worn down especially in overload work. As we know, machinery equipment usually cost much, so we have to know how to keep and maintain it to extend the using life.

Hydraulic system in accordance with the maximum allowed by crushing force crusher hydraulic regulator conditioning nut set, when oil pressure rises,vibrating screen, oil pressure adjusting device of plunger spring compression right shift, driving the piston type fuel injection pump piston counter-clockwise, shorten the piston effective vacation to slow up the quantity of oil, limit system injection pressure rise; Conversely, hydraulic system low, boost the volume of oil, steer clear of the hydraulic system of down, hydraulic system inside the initial set keep hydraulic pressure.

(1) an average work during normal working, crusher thrust board in focus on the role cylinder pressure below hydraulic cylinder thrust, action in limit position about the board, usually do not produce mobile, thrust broken material; normal crusher

(2) overload protection when jaw crusher cavity broken in the crushing object, the broken force increases, this time around jaw crusher thrust board within the cylinder role work pressure is more than the hydraulic cylinder offers the thrust, for ruthless oil cylinder cavity hydraulic transient rise, throttle valve valve movement helps make the movement, the machine (hydraulic cylinder) oil leakage, limit thrust board thrust (this is the biggest force) and largest broken protect the equipment;

(3) the broken out fault things in the crushing cavity, due to work cylinder can offer the utmost limit, the pistons thrust right shift retract, correspondingly crusher row ore enlarges, as well as the mouth with the jaw broken motor gear, the broken gradually downward motion and also the final thing in the ore discharge, automatic eliminate broken mouth cavity inside the broken objects. If broken in to the cavity in the output of the 'broken things products' is unqualified, can remove the auxiliary devices;

(4) automatic recovery every time a broken things out, the piston in automatic after covering position, as the separated, action valve in effect about the instantaneous cavity pressure not make valve core recovery limit position on to never discharge system the oil; Concurrently, piston type fuel injection pump in oil pressure beneath the action of adjusting device towards the largest quantity of oil pump to function oil, before work system cylinder piston moves left to limit position. To date, crusher resume normal work condition.

Frequent occasions in overload, jaw crusher adopts hydraulic overload protection has obvious superiority, the power can be as follows:

(1) safe, reliable, sensitive reaction reliability for protection device is fairly important. The hydraulic protection system in order that the device operation, even when could be the system failure as well as the action can't action,conveyor belt, accumulator with buffer role, could make the thrust board in overload, and with the right shift when pressure relay realize power, alarm;

(2) might be adjusted in line with the different occasions overload load by adjusting device conditioning nut adjust overload load;

(3) after overload protection, automatic may be reliable out fault, faster reset to revive normal production, don't need to replace parts, both economic and time;

(4) facilitate computer operation and control, all to easy to realize and fracture process automation.

Methods and considerations can be given, and concrete measures and plans are done by yourself. Whatever, it will get benefits from the right rules. We Hongxing Mining Machinery Co., Ltd. mainly produces large and medium-sized series mining machinery, metallurgy equipment, building materials equipment, etc.We make a range of grinding equipment and production line. The company has passed through ISO9001:2000.

Recently, 'environmental protection' is important and popular in the world. 'Low-carbon' is the aspect of the subject. Low-carbon life, low-carbon consumption, low-carbon trip... To carry on low-carbon is not just in connection with the effectiveness of our country, living environment and industrial development but additional to each and everyone's health for the long term.

Low-carbon is done from oneself. Zhengzhou is the core of Henan and is the big city. With recent years' development and constructions, the environmental pollution is more and more serious. In construction industry, the machinery equipment is essencial, jaw crusher, impact crusher, excavator, grinding mill machine. To protect the environment, it's efficient to reduce and solve the pollution of construction waste: tailiings, waste water, stone slags. One of the solutions is to recycle the construction waste.

Construction waste recycling is the separation and recycling of recoverable waste materials generated during construction and remodeling. Packaging, new material scraps and old materials and debris all constitute potentially recoverable materials. In renovation, appliances, masonry materials, doors and windows are recyclable. In construction waste recycling, there are some considerations.

Most construction waste goes into landfills, increasing the burden on landfill loading and operation. Waste from sources such as solvents or chemically treated wood can result in soil and water pollution.

Some materials can be recycled directly into the same product for re-use. Others can be reconstituted into other usable products. Unfortunately, recycling that requires reprocessing is not usually economically feasible unless a facility using recycled resources is located near the material source. Many construction waste materials that are still usable can be donated to non-profit organizations. This keeps the material out of the landfill and supports a good cause.

The most important step for recycling of construction waste is on-site separation. Initially, this will take some extra effort and training of construction personnel. Once separation habits are established, on-site separation can be done at little or no additional cost.

The initial step in a construction waste reduction strategy is good planning. Design should be based on standard sizes and materials should be ordered accurately. Additionally, using high quality materials such as engineered products reduces rejects. This approach can reduce the amount of material needing to be recycled and bolster profitability and economy for the builder and customer.

For mining machinery industry, the tailings recovery is also efficient to protect environment. And also the advanced machines: portable crushing station, ultra-fine grinder, high-pressure Raymond mill.

In present, second-hand market is popular ranging from living commodity, clothes, comestics to computers, machinery. In the complex second-hand market, it's optional to make purchase. Which is the best method to choose mining machinery such as jaw crusher, ball mill, coal beneficiation equipment?

Choosing second machinery for running daily operations of a company or an organization is one of the most cost-effective and efficient ways to increase the percentages of productivity levels. Though, going for such an option might involve certain risk factors like how long the machine would function properly or how much time will it take to produce finished goods, they still rule over the hearts of several business entities because of the fact that used machines seem to be a budget friendly option to them.

The prime reason for purchasing second hand machines is that one doesn’t have to spend huge sums of money on their purchase while exceeding their budgets. An organization’s prime growth is judged on the basis of how cost-efficient it is at the time of deciding for its operational activities. Moreover, companies or business entities that are establishing or running out of losses can opt for second hand machine equipments in order to reduce their cost of daily operations and run production processes smoothly and conveniently.

If you wish to purchase or buy second hand machines, searching for a reputed and a reliable used machine dealer can help you sort out the best machine equipment for your business’s daily activities. However, with ever so expanding Internet market, the search for such machinery can also be done through online shopping portals dealing with the sale and purchase of used machine equipments. Although, surveying machines personally by visiting the stores before investing in them is recommended, they can also be bought directly through portals by paying for them through credit or debit cards.

Cement clinker is usually ground using a ball mill. Traditional methods, the ball mill during the processing of materials can usually perform two effects, one is broken effect, one is the grinding effect. General sense, the effect can be broken using other ancillary equipment to complete the crushing. The abrasive effect of the level of its direct impact factors can be attributed to the speed control on the ball. Under normal circumstances, the main ball speed reduction from the basic power distribution unit and drive gear and pulley device control. For the large ball, since the drive motor will start the beginning of a great loss of energy, and because the ball inertia force can not effectively use reducer mill to effectively control speed in a short time.

For cement production line, a breakdown of the number of particles of cement and cement products taste directly linked to the size of ball speed. So, that is, as long as improve their speed by the speed control system produce changes in the material out of or resulting changes in production levels to maintain a constant speed can be a great position to create more profitable business. However, because there are some reverse gear torque limit, can not indefinitely increase ball speed, after reaching a certain level, if that deliberately continue to increase speed, they tend to burn mill reducer drive coil, resulting in equipment discontinued, the general mill maintenance cycle in 1-2 weeks. Such consequences are no different from the enterprise to bring serious economic consequences. Here is the introduction to cement production line's correct method of operating ball mill.

1) the planetary ball mill gear dust cover must be tight to prevent dust from sand intrusion.

2) found gear and main bearing sediment may or invasive treatment should be immediately stopped and cleared, and definitely not delay.

3) the planetary ball mill large tile fever, the occurrence of an accident or near Burnt Burnt should take immediate measures to forced cooling may not stop immediately, to avoid causing 'axle' of accidents.

4) must be strictly enforced to the mining, water supply, add ball is prohibited overload, attention to prevent 'belly up' phenomenon, but not too small for the amount of ore. But does not allow empty-load operation, so as not to bash liner.

5) the screws should be added to the fixed milling hemp liner ring seal to prevent leakage, leakage of plasma.

6) the gap between the liner for the 10-20mm for replacement (when available oxygen welding cutting too tight).

7) planetary ball mill no more than two consecutive starts, the first and second interval of 5 minutes. The third starter must be approved by electricians, fitters with the check before starting.

8) the same shop with a few mill, the two synchronous machine may not start simultaneously.

Apart from ball mill, cement crushers in cement prodction process are very important. Most of the raw materials will have to be crushed before being used to process cement, such as limestone, clay, iron ore and coal, etc. Limestone is the largest amount of raw material during cement production. After limestone mining, limestone is generally of large size and high hardness. Therefore the limestone crushing is very important in the whole material crushing. The common cement crushers are jaw crusher, VSI impact crusher because of the easy principle, convenient maintainence and low cost. However, if the whole cement mining scale is of large size, we usually choose cone crusher or impact crusher to assit jaw crusher and to be secondary or tertiary cement crusher machine.

Global demand to increase over 4% yearly through 2013. Global demand for mining equipment is projected to increase over four percent per year through 2013 to exceed $60 billion. Despite a sluggish outlook in the shorter term, recovery is expected in the mining industry due to rising demand for commodities such as iron ore and copper. In addition, the ongoing global thirst for energy will boost global coal output. China and India will be leading sources of mining equipment demand. However, just as importantly, these nations will continue to fuel demand for mined products throughout the world, thereby providing opportunities for machinery producers.

Developing areas to exhibit above-average growth

Eastern Europe, with extensive mineable resources, is projected to exhibit above average growth in mining equipment demand, along with developing areas of Asia, the Africa/Mideast region and Latin America, with the mature markets of Western Europe and North America trailing. Within the latter two regions, however, are some fairly notable global mining powers, including the US and Canada, each with an abundance of natural resources; and Germany, which is a major source of coal.

Asian markets now dominate other regions

China has shown strong growth in mining equipment demand, a direct result of investment in its local mining industry. For example, coal output more than doubled from 1998 to 2008, reflecting the nation’s intense need for energy. China is also a major source of commodities such as iron ore and bauxite. China has quickly emerged as the world’s largest producer of mining equipment, due in large part to the nation’s growing mining industry. The other largest producers of mining equipment are generally found in the United States and the industrialized nations of Western Europe. Such countries have a long history and extensive expertise in the development of capital equipment industries of all types, which many have leveraged in mining machinery.

Mining is becoming increasingly important to Alaskans looking for good-paying jobs. Not only does the industry provide high wages, the geographical diversity of the mines provides employment opportunities to oftentimes economically challenged rural regions of the vast state. According to the Alaska Department of Labor & Workforce Development, the number of mining jobs in Alaska has jumped 40.3 percent since 2000, almost triple the statewideaverage employment growth of 14.1 percent for the decade.

The Australian minerals industry involves the exploration and mining of minerals (including coal) and the associated minerals processing industry. It is one of Australia’s most important industries and provides direct and indirect benefits to all Australians. In recent months, the unprecedented global growth demand for minerals has slowed considerably and companies in the resources sector are scaling back some operations and planned expansions and a number of workers have been laid off.

Of course, in many other countries or regions, the jobs of mining industry are welcomed similarly. It also drives the growth of mining machinery industry. Mines are often the largest, or among the largest, employers in their borough or census area. Mines also tend to be located in remote areas where other employment opportunities are scarce. For mine safety, high-quality mining equipment is essential. Various models of equipment consists of jaw crusher, impact crusher, grinding mill, beneficiation equipment, mobile crushing plant and so on.

High-quality products and high-standard enterprise management can guarantee stable productivity, high efficiency, safe working environment. Hongxing runs obeying the rules.

Problem on RMB exchange rate has been advertized in large scale. Many western countries put pressures on China around RMB exchange rate. Especially, the issue of Sino-US trade surplus has made the RMB exchange a much more important topic than ever. Since the Chinese government changed its exchange rete regime on July 21st, 2005, studies on further reform steps have become booming. Nevertheless, China government state many times that they will keep RMB exchange rate stable. Of course, with the appreciation of RMB, it brings many significant influence on various industries such as on inflation, especially on its persistence, hence the persistence of shocks to price stability. Henan Hongxing is specializing in exporter of mining machinery equipment. Views on this point, there are some analyses and predictions.

The appreciation of RMB will affect exports, mining machinery include. We can give an simple example. Supposing that Henan Hongxing Machinery Co., Ltd export a new type sand making machine to South Africa, and both sides agree with paying by U.S. dollars, while the equipment price is $25000. If before the appreciation of RMB, the exchange rate is like this $1 = 8.3 yuan RMB, so we can get 207500 yuan RMB from banks; now the RMB exchange rate is $1 = 7.9 yuan RMB. So after appreciation we can only get 197500 yuan from banks. Thus vested interest will reduce greatly, even will make the losses not to keep the exports. As to mining machinery, other exporting enterprises meet the same problems and no exception.

Present RMB exchange rate has raised to $1 = 6.6415 yuan, which breaks through the gate of 6.65 to creat a new top. And also, some specialists predict that the pressure of RMB appreciation is still great and it signs the unstable RMB exchange rate.Under this situation, how to deal with the trend for mining machinery industry? Hongxing company holds the view that mining machinery exporters shall change the main business point and pay more attention on domestic markets. With the development of science and technology, demands on domestic markets are more and more, which will also take great chances and profits. For example, foreign countries has raise the price of steel that affects the domestic crusher industry. Therefore, many enterprises are trying to change the strategies to avoid the attack and loss. At present, China construction industry is prosperous. However, in construction process, mining machinery is essential. For example, jaw crusher, grinding equipment are used widely. So in the trend of RMB influctuation, it's efficient and wise to grasp domestic markets of mining machinery industry.

In task of heavy mining machinery, it's important for equipment model selection and operation. However, later period maintenance is similarly significant. Proper and timely maintenance can extend the life of one equipment. Here, taking cone crushers as the example.

A. the materials must be in the middle of the distributor, see diagram 14. it is not allowed to put the materials into the crushing chamber directly, because it will make the crusher overloaded and the liner plate will be abraded unevenly. Correct feeding conditions :

a. the materials are distributed equally to the crushing chamber.

b. The quantity of materials should not higher than the mortar.

B. the max feeding size should not equal to the feed opening, (the max feeding size=85% of the feed opening) otherwise, it will lead to:

a. the capacity is low

b. some spare parts will be damaged.

c. crusher is not allowed to start in overload condition in case of accident.

d. when stop the crusher, stop the feeder first. After the materials are all discharged out, stop the crusher.

e. the locking system and hydraulic station should be checked often to avoid problems.

Capacity of the crusher

Capacity is subject to feeding method, material size, size of final product, material nature, temperature, etc. the range is wide. The capacity is under certain conditions.

Change of mortar

There are u-shaped bolts on the adjusting ring. Fill zinc alloy into the space. When installing or changing the mortar, after 6-8 hours' operation, check the fastening conditions and screw the U-shaped bolts again.

Change of the crusher inner wall

The Cone crusher inner wall is fixed to the cone crusher body through a cone end. There is zinc alloy between them. When installing or changing the inner wall, after 6-8 hours' operation, check the fastening conditions. If there is loose, fasten it.

Mesh of gears

The friction of round plate changes the gap between gears. To make the gears properly meshed, clients are required to put a mat on the bottom cover. The thickness of the mat should equal to the friction of the round plate.

Bowl-shaped bearing and sealing device

When installing the bowl-shaped bearing, make sure the oil seal is not damaged by the steel cable.

When assembly, scrape the spherical surface to ensure the space between crushing cone and the spherical surface is kept within 0.35-0.5mm.

The bowl-shaped tile is fixed to the bowl-shaped bearing support through lock pins to prevent the tile rotate in circle.

The bowl-shaped bearing support and the frame are fixed together by lock. If there is space between the support and the frame, deal with it immediately.

The cylinder liner and the frame is the third transient assembly.

To avoid the liner rotating, the upper part of liner is filled with zinc alloy. When changing new liner, make sure it is according to the practical size because the after long time's operation and assembly, some changes may happen to the crusher. If the space is too large, the liner will be broken.

Conic liner

The cone cover and the eccentric shaft should wring each other. Fill in some zinc alloy to stop the cover rotating. The space should be full of zinc alloy. The cover may change its shape due to the hot zinc alloy, so check the size of d1, d2 and B of a new cover. If it is incorrect, correct it. When making spare parts, make sure it is fit for the practical size of the inner diameter of eccentric shell.

Springs

A. The function of springs is: when some uncrushed materials enter the crusher, they will prevent crusher from damaging. Therefore, the pressure of the springs and the crusher is corresponding to each other. If the crusher is in good condition, the spring is stable; only when uncrushed materials enter the machine will the springs be pressed.

B. If the upper part of crusher vibrates, clients are required to check the machine carefully and solve the problem. If pressing the springs incorrectly, some parts may be damaged, because pressing the spring will increase the pressure of the crusher.

The reason why the upper parts of crusher vibrate is:

a. feeding unevenly or overfeeding

b. there are many small lump materials in the raw materials or the humidity is too high

c. the discharge opening is too small.

The outer rotation parts of the crusher should be protected with cover which is prepared by clients.

Hongxing impact crushers are the heavy type equipment, and also called sand making machines. The installation and operation both have fixed ruels and instructions. Generally speaking, if you install and use the sand making euqipment according to the following instructions, the equipment using life, product quality and personal safety can be guaranteed. OK, let's list the attentions when installing and operating a sand making machine.

A. When installation, adjust the horizontal position. The machine must have the basic conditions:

1) feeding materials sequent .

2) large pieces of materials can return back to the machine.

3) there is the lifting equipment upon the machine and it can lift the machine conveniently.

4) there is enough space to check up on one side of crusher.

B. Common ruels when operating the sand maker.

1. Preparation works before start-up Sand making machine has a trial run for 4 hours in factory and all parts are in order. However, you must check up the machine again before start-up.

1) Check up turntable is balanceable or not, that is, wearing parts is installed in a whole set or not .

2) The position of triangle belt is suitable or not, that is, strain is suitable or not.

3) All parts are connected steadily or not, and screws are fastened or not 1-4 Check up if there is a tool or sundries in the machine. Close the inspection door and plug into safety bolt. Don't open inspection door when operation. 1-5 Check up the running direction of engine and turntable is correct or not: anticlockwise rotation from the feeding port 1-6 Check up lubrication is enough or not.

2. Start-up without load

1) Ammeter is working or not .

2) The control system: Y/' reducing the pressure start-up; Y/' time transfer relay should be adjusted as 50S or so.

3) Start-up of double electrical machine: Stand-alone start-up and Two engine start-up. You can choose the start-up according to the power of electric network.

3. Start-up with load.

1) Feed the materials after the machine have a successful trial run without load and the running of engine becomes ' type.

2) Max Feed Grain Size must be executed strictly according to instruction.

3) You'd better put in the materials less than 5 mm at the beginning of start-up ( at least in half a minute) so that it can form protection layer in the machine.

4) When you feed the materials at the beginning, there will be a 30-60 seconds imbalance the machine. However, you mustn't stop the machine at once and that feed more materials until the vibration disappears. If there is violent shock and abnormal noise, you should stop the machine to check up carefully.

5) You'd better add magnetic separator beside feeding advice for fear that iron damages the machine chamber in the machine.

6) Max electric current value is not exceed rated current one of running motor when feeding the materials. If the humidity of raw materials is too high, it maybe block the feed opening of central flow and overflow port of scattered flow and influence electric current value. The electric current value is too high and can't be lower because the overflow port of scattered flow is blocked. Contrarily, the feed opening of central flow is blocked. You must stop the machine to clean up all feed openings and then work sequentially.

7) Dual drive motor must regulate and bring the strain of two groups of triangle belts into harmony. Look into two groups of electric current value of motor is accord or not.

4. Stop the machine

1) You must stop feeding the materials before stopping the machine.

2) The ammeter should be without load before stopping the machine.

There are different types of construction that can be performed depending on what needs to be fixed or built in society. For instance one major type of construction is heavy construction. Heavy construction is the type of work that occurs when infrastructure is added to an already built up environment, such as building a highway. Those who own heavy construction projects are typically national or local level government agencies that deal with large contracts that last quite a length of time.

Heavy construction projects are usually done in the best interest of the public to service them better. Of course, it is hard to agree with this when you're stuck in traffic while the roads or the sewers beneath them are being replaced, but indeed the end result has us in mind. That being said, not every heavy construction project is undertaken by the government. Some large, private corporations, such as power companies, harbors, railroads, mines and golf courses, are also involved. These private companies, among others, undertake heavy construction in order to create dams, railways, massive earthwork projects, etc.

Some developments that are considered heavy construction projects include: buildings, parks, playgrounds, apartments, stadiums, factories, malls.

The most important part of heavy construction that makes it successful is the equipment that is used. Heavy construction equipment is essential to the project, because without it, even the basic construction work could never be completed. They are typically quite large, and are created specifically for one or two different uses. The primary equipment used for heavy construction includes but is not limited to: bulldozers, cranes, well drilling machinery, earthmoving equipment, loaders, draglines, cable plows, scrapers, generators, rollers, light towers, etc.

Each piece of heavy construction equipment plays an important role in the project. For instance, as far as groundwork is concerned, heavy rollers are used. Heavy rollers set up the project and find the base. They are then used to raise and drag tons of stones and iron from one place to the next.

The biggest problem that often occurs with heavy construction is the cost of building. Heavy equipment is quite expensive, and the people needed to work these machines and tools need to have the skill and experience in order to handle them. That being the case, many companies make the decision to rent or lease heavy equipment, sometimes even with or without the operators.

Unfortunately, because operators need to have both the skill and knowledge to work the equipment, they have become practically as indispensable as the heavy equipment. This can sometimes cause problems for companies who require heavy construction projects. To beat this problem, some companies hire people and then pay for their training, as opposed to trying to find someone who already has the training and is therefore going to request a much higher salary.

Despite certain problems, and expenses, most heavy construction projects are completed. The result of a heavy construction project is usually something that many people can benefit from and enjoy.

The mining industry in many developing and third world countries has, over the last ten to fifteen years, undergone a great growth period. New methods of finding minerals have been discovered and it has caused old mines to be re-opened and new mines to begin. Mining involves a fairly simple principle of extracting minerals from the earth and refining this raw material to finish with an end product. These products, such as gold, silver, iron ore, copper or lead, are all very valuable in our world at present. The gold prices today are at record highs. This leads to many new mine companies starting up or old ones to go through rapid growth periods.

The primitive mining methods existent thousands of years ago, have now been replaced by new methods involving machines. People used to dig away at a mountain by hand or by use of small hand implements. Then came the use of horses and animals as power, which made the work easier and more feasible. This was still not such a big deal until the invention of the combustion engine and therefore machines just like belt conveyor, cone crusher specifically designed for mining. Once this happened it changed mining dramatically.

These machines such as jaw crusher, impact crusher, ball mill, Raymond mill are used extensively today and are the backbone of the business. The mining techniques used vary greatly depending on the landscape or the location of the ore being extracted. Underground and open-cut are two main ways of mining. Underground mining requires special low height machines such as loaders, tippers and patrol cars. They can drive along tunnels of a very low height. Mining out in the open is done with many machines. Big bulldozers, drag-lines, tippers, excavators, graders and pile drivers. Many cars are also needed for a mine site to function properly.

When mining is in progress, the large company that normally has the mining rights, often employs many sub companies to do the actual excavating. These sub-contractors have a lot of the machines on a mine site. These machines are often leased. This means they are not owned by the contractors but borrowed off another company for use. This is quite a common practice and also a very well functioning one. It involves the companies paying rent money to have new and very valuable machines at their disposal. This is normally the way it has to be as no body can afford to capitally invest into so many machines. It works well because the machines are often newer and function better than older, more out-dated machines, that the people could afford.

This is great for all parties as it maximizes progress and everybody is making money. When the down-time and maintenance is reduced, then is it better for everybody. It it a good way for small businesses to start up and run. The idea has been around for some time and is very beneficial to profit making. Mining is an industry that never stops and this is a good way to help you out in these tough economic times.

Do you want to be the Hero of your company industry? If you are interested in having business in excavation, you will find that this might be totally different with other businesses. You can start a business in this field by doing some efforts. In the matter, you have to prepare the equipment that you need and the commitment to run this business. The followings are some things that you can look at so that you will get the easiness in starting excavation business that you want.

Firstly, you should get the permission from the authorized organization to run excavation business. Make sure that everything that you do such as dig the land or operate the machinery. You have to make everything in your business legal. This will allow run the business smoothly as everything has been legalized.

With the continuous growth of China's economic construction, the domestic real estate and the construction of the continuous development of high-speed highway, making the small crusher industry has also been rapid development.

The production of small crusher crusher developed from a single specification to a variety of specifications of various models of a variety of small crusher. One of the new small crusher crusher complex sales market is gradually opening to the development of composite crusher sales than in previous years are also far improved significantly. Here we will show you a small crusher manufacturing capacity issues as reflected in the development of composite crusher found.

Small crusher crushing capacity per unit time is the amount of broken material, with the tons / hour. Impact crusher capacity by many factors:

First, the material hardness. The more rigid the material broken up the more difficult and more serious wear and tear on equipment. Slow broken, of course, crushing capacity is small.

Second, the humidity of materials, materials containing water that is larger, the contents of the material in the crusher easy to adhere, but also easy to plug the next conveying process, resulting in crushing capacity decreases.

Third, the fineness of the material after crushing, high fineness, which requires breaking out of the finer material, the crushing capacity is smaller.

Fourth, the material composition of the material before crushing the powder in with the more impact crusher, because they affect the adhesion of powder is easy to transport. For the powder content and should advance once sieve. To increase production capacity.

Representative products are composite crusher, first to pass a string of numbers to illustrate the composite crusher industries, the global annual compound crusher as much as one hundred million tons of materials to several hundred, but only China's annual compound crusher of a variety of materials is about 20 million. Thus, in the production of composite crusher industry energy saving, high-tech composite crusher is crushing the future of composite machinery industry is a major trend.

Since the 'eleventh five-year plan', the equipment manufacturing industry, especially the mining machinery industry made astounding developments, the industry system constantly improved and perfected, the technology innovation ability significantly enhanced and the international status and influence increased obviously. At the same time, the strength of Chinese enterprises also continued to advance. At present, China has become a mining machinery manufacturer in global scope in realty as well as in name. Chinese leading mining machinery manufacturing companies with Henan Hongxing Mining Machinery Co.,Ltd as a representative have seen continuous breakthrough in the enhancement of products and innovation ability, and at the same time all-round improvement in the ability of global resource control and application and market penetration.

“Innovation is the soul of a nation's progress, is an inexhaustible motive force for national prosperity.” Take a panaramic view of today's international economic competition, it is the competition of technology that matters the most. It is true to a nation, so is true to an enterprise on the front edge of fierce market and economic competition. Only by way of continuous innovation of science and technology can an enterprise maintain the vitality of sustainable development.

For the mining machinery industry it is no exception. Especially for Henan Hongxing Mining Machinery Company, as the representative of the mining crusher industry, mining machinery is an important guarantee of the development of the national economy,one of the strategic industry that the country makes great efforts to establish, and also the important guarantee of mine industrial upgrading and technical progress and most importantly, the centralized embodiment of national comprehensive strength and technical level.

But as a developing country, China's industrial development started very late, and the foundation is weak, so the difficulty and pressure can only be imagined to to complete in just a few years the modernization what western developed countries did with hundreds of years time. In the face of western countries’ technology, therefore, it is imperative to speed up the pace of technological innovation. Especially the leading companies in the mining machinery industry shoulder the burden of engineering equipment localization in order to guarantee the implementation of infrastructure construction and strategy of energy construction.

Big and small mining enterprises are dotted with uneven level and lack large crusher professional knowledge and operation experience, all of which bring hidden trouble to the mine safety and long-term and healthy industry development. Henan Hongxing Mining Machinery also realized this problem and launched special research and development targeting construction safety conditions and safety control of a large tonnage products. Hongxing Machienry simulated all kinds of construction conditions and significantly increased the simulated practical projects. But it is far from enough only with the the related technical support of manufacturers. Only by strengthening the safety management of and supervision to construction enterprises can those problems be solved in nature.

Admittedly, as for short-time benefit, enterprise innovation is a risky behavior. Especially for technology oriented national engineering machinery enterprise with Henan Hongxing Mining Machinery Co.,Ltd as a representative, the pressure is incredibly huge. In the core technology, developed western countries have set a lot of barriers. The mining machinery industry shouldering the important responsibility of reviving national strategy should increase the strength of innovation and keep the technology leading position.

Hello, everyone! The new year is coming accompanied with some safety problems. If you celebrate too much on New Year's Eve, by all means take a taxi home. But make sure you aren't leaving your own car vulnerable to be stolen.

Thieves steal more cars on New Year's Day than any other holiday, according to the National Insurance Crime Bureau -2,347 last New Year's. Many cars are sitting in parking lots or other locations away from home, some of them unlocked.

'Thieves never miss an opportunity to make a quick buck by stealing a car. They work nights, weekends and holidays,' cautions Joe Wehrle, president of the NICB.

After New Year's Day, the holiday with the most auto theft is Memorial Day. The day with more car thefts than any other is a shifting date in the summer, usually in July or August.

If you want to have a good time on New Year's Eve and not have a missing car be part of the hangover, follow these tips:

• Leave your car at home. Take a taxi or mass transit to your celebration. Or, if you have a selfless friend, go with a designated driver.
• If you do drive and leave your car, make sure it is locked and the alarm is activated.
• Park the car in a well-lighted, very visible place.
• Don't leave holiday presents or other attractive targets in the car that could lure a thief to break in.

Plan your New Year's Eve carefully. For sure, don't get in an accident or arrested for drunk driving. But don't get your car stolen either.

Mountain mechanical applications and infrastructure are closely related, the future will have a huge market. However, industry believes that the overall mining machinery in China with the international advanced level compared to 15 to 20 years behind most sources of technology products for the mid-1980s from abroad. Domestic market share of mining machinery products in the market less than 80% in the imported products are mostly large, fine, sharp and strong sets of products, such as coal mining, large efficient separation equipment, crushing and grinding equipment, all joint cross-section boring machine and other products.

Mining machinery industry's technological base is not strong, reform and opening up, has been in the field of mining machinery market for technology to improve product technology level as the main way. Throughout the world the development of mechanical design process, mainly stand-alone single product design to product design to process equipment design process evolution. China's general mining machinery manufacturing completed only stand-alone product design and manufacturing equipment used in the design process to do by a professional institute, the craft of stand-alone product requirements proposed by the professional design institutes and assist manufacturers to complete, which resulted in equipment manufacturer and device disconnect between departments. Experts believe that in the current mining machinery manufacturing industry, the business process design is relatively weak in the case, good condition, except in their own areas of expertise into the role of organizational strength as soon as possible, should be taken with foreign and domestic companies to establish various forms of professional institute joint, including the formation of groups, unions, the introduction of technology, the introduction of qualified personnel and other measures to fight in a joint project on the design approach, the first intervention and then to improve and achieve win-win situation.

In addition, experts suggest that as quickly as possible, to supplement and improve the application of the advantages of professional laboratory for product, manufacturing process and process technology research. Not applied technical research data and databases, you can not convince customers to use the company's products and technology, not to mention the truly innovative application of technology.

According to the characteristics of the mining machinery, the lubrication oil should meet the following requirements:

1). The size and oil tank capacity of the mining machinery are rather small, and the storage of the lubrication oil is very limited, so when the machine is working, the oil temperature will be very high, which demands that the lubrication oil must have strong thermal stability and antioxidant ability.

2). It is hard to avoid being polluted by the surrounding impurities because of the hostile environment, coal and rock dust, high humidity. So the lubrication oil must have the ability of antirust, anti-corrosion and demulsification. Though polluted, its capability should stay the same, namely it should be slightly sensitive to the pollution.

3). Opencast mining machinery has to suffer the great temperature difference between summer and winter or day and night. So the lubrication viscosity shouldn’t change a lot with temperature. Both to avoid malfunction caused by too low viscosity that restrain the oil from forming lubricating film in high temperature and hard to start or run caused by too high viscosity in low temperature.

4). Some mine are very vulnerable to major fires, so we should choose anti-fired oil instead of the flammable mineral one.

5). To avoid damaging the seals, good adaptability is required for lubricant.

For a long time, ball mill has been a key equipment for high capacity grinding demand. Nowadays, vertical mill will be active in this field. You must want to know the comparison between them, please read as follows:

1). Higher grinding efficiency. Vertical mill grind material in material bed, engergy cost will be 30% lower than ball mill, as sound engergy and thermal energy will cause energy loss in ball mill.

2). Simpler process flow and less investment need in infrastructure. Simpler design in powder transmission ensures less breakdown time and better operation; compact arrangement requires only 70% building area and 50%-60% building space of that for ball mill.

3). Excellent performance in drying. As material is transferred by hot steam, wind temprature can be controlled to dry material with moisture of 12%-15% ready for grinding, while that for ball mill can only be 3%-4%.

4). Less consumption of metal parts. As there is no direct contact between different metal parts, metal consumption and iron content of final product will be reduced a lot, which will be good for final product quality.

5). Less noise and dust. Noise can be reduced by 20-25 db comparing with ball mill and dust will be reduced greatly thanks to it’s subpressure design.

6). Powder is more even. As qualified products can be seperated in time and over grinding can be avoided, which can provide more even powder comparing with ball mill, in which over grinding is inevitable. Meanwhile, grain size can be adjusted easily by a unique system.

As people know, mining industry is treated as the most difficult and dangerous economic activities.

It's the products of this activity that allow society to function the way it does today. One can only imagine what life would be like without the products of mining. Daily activities would be hindered without the production of natural minerals and coal; not to mention its effects on economic activity. Luxuries like jewelry also come as a result of the mining of precious metals.

Methods have developed greatly over the centuries. Matter of fact, major developments happen on a daily basis. New sciences and technologies allow the industry to grow and provide more for the world. Many people are unaware, however, of the methods and procedures that go into the mining process.

There are two common excavation techniques used today: surface and sub-surface or underground mining. The more common of the two is surface mining seeing as it produces a majority of the world's minerals.

Surface mining, as its name might suggest, is the easier of the two. The technique involves the removal of material that can be found on the surface such as vegetation or dirt. If necessary, miners dig into the bedrock to reach the deposits they are aiming for. This technique employs the use of one of five further forms of surface mining. These include strip, open-pit, mountaintop removal, dredging, and high wall mining.

Sub-surface mining, on the other hand, is the exact opposite of surface mining. This technique involves the digging of tunnels deep into the earth's surface to reach the deposit. The products of this type of process are then brought out through the tunnels and shafts created. Unlike surface mining, which is classified into five forms, sub-surface mining is classified by the type of access shaft used to extract whatever mineral needs extraction.

Advancements in mining equipment such as green light laser technology have made it much easier for miners to do their work. Most people are unaware that laser technology plays a big role in the success of any mining operation. Red light lasers used to be the standard, but green light lasers are starting to become more widely used. This is because green light is apparently much stronger than the red light, and is also visible under direct sunlight.

People tend to confuse the petroleum industry as being part of the mining industry, but this is not the case. It's easy to confuse the two, considering that the retrieval of petroleum involves the gathering of a product that is below the surface. Petroleum, however, is not mined like other minerals. This is because petroleum is in a liquid state; for it to be retrieved, it needs to be pumped out.
