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.
