Ball mill, as a common grinding equipment, was widely used in beneficiation, construction materials and chemical industries. In terms of grinding way, ball mill can be divided into two types：wet type and dry type. And in terms of discharge mode, ball mill can be divided into overflow -type and lattice-type.

Generally speaking, there are three direct ways to improve productivity. before using ball mill, use a crusher first. Improve the design of ball mill, so the grinding efficiency can be improved.use a efficient classifier in the production line .As we all know, ball mill is an important equipment used to grinding materials after primary crushing.Ball mill is widely used in cement, silicate product , new building materials , refractory materials , fertilizer, black and non-ferrous mineral and glass ceramics and production industries, and all kinds of ores and grind-able materials can be grinded through dry or wet grinding ways.The above three methods , any one can greatly improve mill yield . Of course, if conditions permit, supporting the use of the above three methods , the effect is the most ideal.This is the design trend of grinding system domestically and internationally in recent years.

Crushing the materials before grinding by mill makes the particle size greatly reduced , thereby reducing the grinding system load ; the most direct benefit of the improvement of separator efficiency is that fine finished product be discharged in time, so the the rate of finished product back to the cement powder was greatly reduced and reduce the load of ball mill; the particle size into the mill was reduced, separator efficiency was improved, so both the productivity and materials quality can be improved.Our ball mill plants are used to process limestone , basalt, chrome , dolomite, feldspar, fluorite, kaolin ore, marble , granite , iron ore ,copper ore , sandstone, silica , gold ore , silver ore , lead ore ,with capacity 1000 to 5000 tph,we’ll give our customers adjust advice for the mining solution.Our engineer will accompany you to research you mining and construction industry to be solved.

Finely made into the ground before grinding material particle size reduced greatly, which reduces the grinding system load; Choose to enhance the efficiency of powder, the most direct benefit is finished product fine powder is maximum elected in time, reduce the cement products back to powder rate, reduce the mill load; And grinding of reform, is also the grinding system improvement, is the most fundamental solution. Into the ground material particle size reduced, select the powder efficiency raised, if griding system efficiency is low, the impact is not only the mill production, more affecting quality.

It also enables large-scale integration of renewable energy into the power grids.

Saving energy can help cut your household costs and benefit the environment. A significant portion of energy expenditure in the home goes into running appliances. Making sure appliances run efficiently can reduce waste and make for a more environmentally friendly home. There are opportunities for saving energy in appliances throughout the home.

Environmental protection is a practice of protecting the environment, on individual, organizational or governmental levels, for the benefit of the natural environment and (or) humans. Due to the pressures of population and technology, the biophysical environment is being degraded, sometimes permanently. This has been recognized, and governments have begun placing restraints on activities that caused environmental degradation. Since the 1960s, activism by the environmental movement has created awareness of the various environmental issues. There is not a full agreement on the extent of the environmental impact of human activity, and protection measures are occasionally criticized.

Hoisting equipment is oriented on the safety and reliable work, which adopts the computer control and dynamic measurement technique on the working life and efficiency and the build-in attrition elevator on the machine structure. The crushing equipment adopts hammer double-rotor impact crusher and the product structure is developing for the fine crushing. The development of high-new equipment requires plentiful functional materials and the application of modern fine crushing technology has become an important symbol of embodying the national technology level.

Many of the earth’s resources are especially vulnerable because they are influenced by human impacts across many countries. As a result of this, many attempts are made by countries to develop agreements that are signed by multiple governments to prevent dam age or manage the impacts of human activity on natural resources.

Cone crusher is suitable to crush various kinds of ores and rocks of medium or above medium hardness. Compare with jaw crusher, cone crusher is of stable structure, high efficiency, easy adjustment, economic operation, etc.

Spring cone crusher is cone crusher which is the earliest appearance in the world, and it is used widest and larger quantity crush mechanism at present. The Spring Cone crusher is generally used as a secondary crusher in a stone production line. The spring safety system of crusher acts as an overloading protection system that allows metal to pass through the crushing chamber so as not to damage the cone crusher. The safety system uses dry oil and water as two kinds of sealed formation to make plaster powder and engine oil separate to make sure reliable performance. The type of crushing chamber depends upon size of feeding and fineness of crushed product. The standard type (PYB) is applied to medium crushing, the medium type is applied to medium or fine crushing and the short head type is applied to fine crushing.

With the development of the series of spring cone crusher, its structure is more perfect than before and the technology parameter is more advanced, so these crushers have excellent performance in the aspects of manufacture, installation, use and maintenance etc. The spring cone crusher belongs to the cone crusher, in the stone production line, there are some other crushers such as jaw crusher, impact crusher, vibrating feeder and vibrating screen.

Spring cone crushers are widely used in industries like metallurgy, construction, road building, chemistry etc, to crush many kinds of mid-hard or hard rocks and ores such as iron ore, limestone, granite, basalt, quartz etc. The standard spring cone crushers are used for secondary crushing; the medium ones are used for fine crushing; and the short head ones are used for super thin crushing. The spring cone crusher is characterized by a reliable structure, high efficiency, easy adjustment and economic. The spring safety system prevents overload so that hard materials (such as iron) are processed through the crushing chamber without damaging the machine. Spring cone crushers are run on belt drives driven by an electric motor or diesel engine. Cone crushers are used extensively throughout the aggregate and mineral processing industry.

The working principle of spring cone crusher: spring cone crusher crushes materials by the working surface between the movable cone and fixed cone. So spring cone crusher is more advanced and efficiency. The movable cone is supported by spherical bearing and fixed on an hanging vertical shaft which is set in the eccentric sleeve, and the sleeve is set on the stopping and pushing bearing. The movable cone and vertical shaft are driven by the eccentric shaft sleeve together. The eccentric shaft sleeve is driven by horizontal shaft and fimbriated gear, and the wheel of the conveyor belt is driven by motor through v-belts. The lower part of vertical shaft is installed in the eccentric sleeve. When the eccentric sleeve rotates, there is a conical surface lined out by the shaft. When the movable cone comes near the fixed cone, rocks are grinded into pieces, when the cone leaves, grinded materials is discharged from the discharge hole. The fixed cone can be ascended or descended by adjusting setting to adjust the width of discharge hole, consequently the output size is determined.

Compared with jaw crusher, spring cone crusher has the advantage of low operation costs, high productivity, easy adjustment and stable structure. The spring cone crusher has higher capacity and the products with high quality. Because spring cone crusher has safety device, the parking time has been reduced greatly. The machine is cast steel structure and on the heavy load pat equip with dabber. The spring cone crusher equips with adjuster, it can adjust the discharge particle size to meet different demands. The spring cone crusher has a whole lubrication system, it can self-close once the oil temperature is too high or overflow. The inner structure of spring cone crusher has good sealing property. This will protect spring cone crusher from damage of dust. Spring cone crusher has long using life and high applicability. This spring cone crusher can be equipped with other equipments in the stone production line or sand making production line.

The VSI sand maker machine made sand is made of river cobble and cobblestone, and processed by crusher machines and VSI sand makers, or other accessory equipments. This artificial sand can replace the natural sand, and even much better for construction than the natural sand.

Henan Hongxing is a manufacturer who produces the VSI sand makers based on the various processing requirement as well as the sand particle size, VSI sand maker can further meet the day-to-day needs of mining operating location. The VSI sand maker is broadly employed within high way, railway transport, water conservancy as well as other sectors. This VSI sand maker is suitable for metal and nonmetal ore, construction material, artificial sand as well as other types of metallurgy slag. This VSI sand generating machine is used inside the brittle material using the moh’s hardness much less than 9 degree, it not suitable for the viscous material or the stone material with a lot of soil.

Based on the above, it's the issue that how to choose the correct and proper VSI Sand Making Machine.

From the technological requirement, sometimes people just require the maximum particle size limited value, the fine powder can not exceed the limited value. Sometimes people not only require the particle size, but the particle shape. So the requirement of VSI sand maker is also strictly. For example, as the concrete aggregate, there is not only requirement on the product particle size, but also require the particle shape must be cubic. It is better with edge angle, this can promote the strengthen of concrete. In the sand making production line, the products particle size must be ensure by the third generation sand making machine-VSI high efficiency sand maker. As used for steelmaking material, limestone particle size must be controlled in a certain range, and not or less produce the powder.

In addition, the main consumption of VSI sand maker, inside the crushing plant, besides the typical wears of VSI sand maker, electric energy, steel consumption, lubrication, water and rubber belt are the primary consumption aspects. The consumption volume is distinct according to the ore constitute, mine sort, hardness, crushing flow and crushing ratio. So to be able to minimize power consumption, inside the crushing plant, folks should boost the processing capacity of each stage, reduce the VSI crusher empty operation to achieve the best economy benefit and lower the unit consumption.

Henan Hongxing connects the informatization technology and improved the work efficiency to solve the VSI sand makers problem, this promoted the VSI sand maker crushing ratio and reduced the wear and energy consumption. At the present condition of economic development, the VSI sand makers will have high use value in the mining machinery industry.

With the gradual improvement and promotion of the steam engine and electric motor power machinery ,various crushers have been invented. After several improvements, the crushers have become what we are using now. with the requirements of the people, crushers will be further changed, then let us review the crusher history.

In 1806,steam-driven roll crusher appeared.In 1858,American EW Black invented the jaw crusher.1980s,a large jaw crusher’s material size(average diameter of abrasive)which can crusher 800 tons of material per hour had reached about 1800mm.In 1878,American Charles Brown invented the gyratory crusher with continuous work.The Gates Iron Works sold its first gyratory crusher Chicago in 1981.In 1953,U.S.Allis-Chalmers gyratory crusher hydraulic launched.The early 1970s,large gyratory crusher has been able to handle material per hour,5000 tons,the maximum size up to 2000mm.The late 1970s,the U.S.launch of super-heavy company Rexnord gyratory crusher.80 years,Sweden has introduced a new top Morgards Hammer gyratory crusher hydraulic cy linder.In 1984,China successfully developed the 1200 light-duty hydraulic gyratory crusher.

In 1858, American EW Black invented the jaw crusher. 1980s, crushing 800 tons of material per hour, a large jaw crusher feed size (average diameter of abrasive) has reached about 1800 mm.

In 1878, American Charles Brown invented the gyratory crusher withcontinuous work. The Gates Iron Works sold its first gyratory crusher Chicago in 1881 .In 1953 ，U.S. Allis-Chalmers gyratory crusher hydraulic launched. The early 1970s, large gyratory crusher has been able to handle material per hour, 5000 tons, the maximum size up to 2000 mm. The late 1970s, the U.S. launch of super-heavy company Rexnord gyratory crusher. 80 years, Sweden has introduced a new top Morgards Hammer gyratory crusher hydraulic cylinder. In 1984, China successfully developed the 1200 light-duty hydraulic gyratory crusher.

In 1895,the United States William invented a low energy impact crusher.In 1920,theoriginal design by the Americans Simmons brothers began to be used cone crusher concentrator.In 1948 the company developed into a U.S.AC hydraulic cone crusher.70 years for the development of control hydraulic cone crusher automatic controller.

In 1924,the Germans developed a crusher,its structure is similar to a modern squirrel cage crusher,1942,German Andreson on the basis of previous experience,and the invention of modern crusher structure similar AP series impact crusher,crusher of the kind of the kind after the Second World War(1945)appeared in the market.

Nowdays,the development of crusher is rapid,let us share some new crushers. Crushers includes many different types such as jaw crusher, cone crusher and impact crusher as well as vertical shaft impact crusher which is also called sand making machine. In addition, mobile crusher is also an important machine which is suitable for small miners. Symons crusher and HP series cone crusher are suitable for high hardness stones and varies minerals. Generally, whole crushing plant contains primary crusher, secondary crusher and tertiary crusher as well as some auxiliary machines such as vibrating feeder, belt conveyor and vibrating screen.

Most ores contain less than 10% lead, and ores containing as little as 3% lead can be economically exploited. Ores are crushed and concentrated by froth flotation typically to 70% or more. When lead is exploited to the ground, it’s should be crushed or grinded for its further application. Lead ore crusher will act as the primary crushing equipment in lead ore crushing plant So now the PEW sequence of Jaw crusher has most unquestionably change to the earth most welcome crusher .And you might make your mind up upon the PEW sequence of jaw crusher while using earth superior crushing and production solutions as quickly when you desire to crush the products featuring very hard and big erosion.

We can supply many lead ore curshers such as lead jaw crusher, lead impact crusher, lead cone crusher, lead mobile crusher and so on. Metallic lead that results from the roasting and blast furnace processes still contains significant contaminants of arsenic, antimony, bismuth, zinc, copper, silver, and gold. Lead ore crushers are used widely in such ore curshing industry. Since the establishment, Hongxing has grown to become the largest crusher and screening equipment dealer in the China. So, if you want some lead ore or other ore mining equipments or crushing machines, you can come to visit Hongxing which must be your good choice.

Lead oxide from the roasting process is reduced in a coke-fired blast furnace.[6] This converts most of the lead to its metallic form. Three additional layers separate in the process and float to the top of the metallic lead. These are slag (silicates containing 1.5% lead), matte (sulfides containing 15% lead), and speiss (arsenides of iron and copper). These wastes contain concentrations of copper, zinc, cadmium, and bismuth that can be recovered economically, as can their content of unreduced lead.

Metallic lead that results from the roasting and blast furnace processes still contains significant contaminants of arsenic, antimony, bismuth, zinc, copper, silver, and gold. The melt is treated in a reverberatory furnace with air, steam, and sulfur, which oxidizes the contaminants except silver, gold, and bismuth. The oxidized contaminants are removed by drossing, where they float to the top and are skimmed off.

Lead hammer crushers are widely used in small quarries with small capacities. That’s because in such situation, the cost and the difficulty of changing and maintaining worn hammers are more acceptable to the quarry owners. However, once the quarry owners want to enhance the capacity to above 50-60t/h by one crushing plant, hammer crushers are no longer suitable. Using hammer crusher to do a big crushing work will lead to a passive situation .

As is known to all, production of main raw material is limestone cement. In the most ordinary staple stones, use the equipment is mainly a counterattack crusher. Refers to the cement production process two materials according to certain proportion into a counterattack crusher for broken production process. Common mixed broken with mud limestone, a limestone with limestone and clay shale and limestone.

Mixed broken succeed, can reduce or exempt the dissection, elongate-shaped limestone ore resources more fully. Two kinds of raw material processing reduced together a set of processing system construction and operating expenses, cement mixed crushing process to ensure the grain-size meet the requirements of the grinding, prevent crusher cavity jams, ensure the smooth operation of the system. Therefore, the whole system from bunker up will be special design, including the shape, structure, the broken silo before group, the mud inside and funnel chop special treatment and chute, etc.

The rotor is crusher 'heart', and is also the most restrictive impact breaker acceptance of parts, which in the work plays a vital role. So the company developed and produced structure solid heavy rotor to obtain higher rotation inertia. High wear-resisting material and the best crushing cavity, making the performance of the crusher epic. By hydraulic impact breaker crushing technology bring the mixture in the process of advantage: broken by wet limestone broken material feeding package, dust reduce, formation of crushed stone and wet earth asphalt-measuring viscosity decrease, liquidity increases, reducing valve with the congestion, with belt conveyor in transport and stacking prehomogenization in the performance of stocks and rake take.

Hydraulic impact breaker is very suitable for crushing various soft and hard ore in, crushing, crushing, finely assignments, slag, gangue, coal ash of materials, such as cooperate mandibles crusher, impact crusher etc processing, can replace limestone, produce cement. A sticky soil high aluminium material and industrial waste residue (such as slag, fly ash, coal gangue) as main raw materials, add 5% of special additives, sintering temperature just 700 degrees Celsius, the energy consumption only ordinary cement 1/2 geological polymer cement new technology, this kind of cement don’t need limestone, fuel consumption is small, can reduce 50% coal burning, so dust and gas, and reduce the amount of waste materials, the cement is 50% la discount strength label is ordinary cement 2 ~ 3 times, such as used in building roads just half the thickness.

Global mining firms are unearthing ingenious solutions to grapple with shortages of workers and equipment amid the commodities boom, recruiting retired miners and buying cut-rate equipment from China and Russia, executives said this week. 'We hired some guys out of retirement, that was the only way to survive and get the skills in place,' said Pekka Pera, chief executive of Talvivaara, a Finnish firm building a new nickel and zinc mine.

Mining firms innovate to cope with labour and equipment shortages Eric OnstadMining firms, trying to cope with shortages of skilled workers and equipment, have been forced to innovate and adopt new solutions, rehiring retired mineworkers and buying cheaper equipment from China and Russia.

Different mining firms in different countries have various methods and policies.

Pera and other executives told the Reuters Global Mining Summit the key was taking advantage of local situations to surmount obstacles thrown up by a global rush to build new mines as metal prices soar to fresh peaks.

The Finnish firm realised that the depressed region around the mine had a lot young untrained and unemployed people, but also a number of retired miners.

Training and keeping workers was the biggest challenge for Major Drilling Group, one of the world's biggest mine drilling companies, Chief Executive Francis McGuire said.

'It takes three to five years to train a driller and it is a very, very skills intensive industry,' he said.

On the equipment side, Peter Hambro, executive chairman of the Russian gold producer that carries his name, said his firm had slashed costs by local purchasing.

The tyre situation has improved, but a lack of them was one reason behind a fall in production last year at the world's biggest diamond mines in Botswana, said Sheila Khama, the head of De Beers in that country.

Right now, big shortages and long lead times were being seen in mills, said Peter Marrone, chief executive of Canada's Yamana Gold.

His firm managed to keep expansion projects on schedule by ordering mills even before the board had formally approved building the new mines.

Construction waste recycling is to different crushing equipment, screening equipment, transmission equipment and equipment to remove impurities with a reasonable production assembly process.

Construction waste in many of the waste by sorting, removed or crushed, most of them can re-use as a renewable resource. Such as scrap steel, scrap wire, scrap wire and other metal by sorting, concentration, re-melted, it can be processed into all kinds of steel; waste bamboo, wood can be used to make artificial wood.

If enterprises can reuse and recycle construction waste well, the crushing equipment productivity must be pushed forward. Of course, in addition to this aspect, influence of crushing equipment productivity there are many factors, including internal and external factors, internal is broken, the functions and characteristics of mechanical itself is material properties outside influence. Specific as follows:

1) material of hardness. The more hard material broken up, and the more difficult for equipment wear and tear the more serious. Broken slow, of course, crushing small ability.

2) materials, namely material containing the humidity of moisture is bigger, within easy adhesion material in crusher, also easy to next material transporting process jams, causing broken ability decrease.

3) crushing the fineness of materials, high fineness requirement, which requires broken out of the fine, the material crushing ability and smaller.

4) material composition, the broken in the former materials containing powder more many more influence, because these fine powder crushing to affect delivery. Adhesion For fine powder content more should advance once sieve.

5) material viscosity. Namely material viscosity, the bigger the more easily adhesion.

6) crushing equipment broken pieces (hammer) wear resistance, the better broken, the greater the if not wear-resisting ability will affect the crushing ability .

The advanced technology is the main factor of development, the development in China of the urban and rural is a kind of solidarity, they are promoted each other and influenced each other. While the R & D of new sand making machine will make the township economic in our country develops rapidly. New sand making machine is one of the ideal equipment producing mechanism sand, cushion material, asphalt concrete and cement concrete aggregate. Which is widely used in highway, construction and other fields and called new sand making machine for impact crusher. New sand making machine is grinding and crushing materials by the material mutual collision and friction between materials, therefore it is suitable for the coarse and hard crushing of hard, medium hard and abrasive materials.

Sand making machine is the equipment which makes sand artificially. It can be impact crusher or cone crusher according to the materiel condition and production requirement.

In the working process of the new sand making machine, a swirling crushing chamber is particularly important; the structure shape of the swirling crushing chamber structure shape is a annular space composed by the upper and below two cylinder. The crushing of the materials proceeds in swirling crushing chamber and the crushing effect is limited to the materials, which can play a role of to wear resistant as a lining; the observation hole is used for observing the wear pattern of the wear-resistant block in the impeller emission outlet flow passage and the linear at the top of swirling crushing chamber, the observation must be strictly sealed when the machine works; the distributor is fixed to the upper cylindrical of the swirling crushing chamber; when the impeller rotates at high speed, it will generate air flow which will through the distributor in swirling crushing chamber and the impeller forms internal self circulation system; at last the fine material will discharge out from the opening.

The sand making machine is especial suitable for making building sand and paving sand. Because of its low wearable feature, sand making machine is also used in high abrasiveness and secondary crushing industry. Besides, because there is no pollution for machine, sand making machine is well suitable for producting glass quartz sand and other high purity material industry. Its production capacity scopes is 10-500t/h., so sand making machine almost can satisfies all production requirement.

With the continuously development of Chinese economy, the machinery industry has continued to expand and the machinery is widely applied to large-scale construction, believe that after many years' experience in the mineral processing equipment production areas, we will provide more perfect and excellent performance sand or gravel production line for the market. I believe that in the near future China's development will be more quickly, rural development will make a spurt of progress.

A computer simulation, a computer model, or a computational model is a computer program, or network of computers, that attempts to simulate an abstract model of a particular system. Computer simulations have become a useful part of mathematical modeling of many natural systems in physics (computational physics), astrophysics, chemistry and biology, human systems in economics, psychology, social science, and engineering.

It is from the last century that people from foreign country had optimized the structure and cavity of the jaw crusher by the computer simulating technology, they had developed the new jaw crusher with characteristics of no plug point, low height, light weight, good product particle, high yield, high performance and low power consumption, which thereby greatly improved the performance of the jaw crusher, shortened the developing cycle of product and improved the competitiveness of the product in the market. However, the simulating optimization design of the jaw crusher in China was mainly limited to the specific models of jaw crusher to prepare the corresponding procedure to optimize the design. And these procedures are mostly with little reusability, which can only solve the specific issues of particular jaw crusher. However, the optimized content of a crusher changes frequently with different requirements of different customers, so the simulation optimization design work needs large repeated and cumbersome programming work, which is time-consuming and laborious as well as extends the developing cycle of the product.

Jaw crusher is widely used in mining, metallurgy, building materials, highway, railway, water and chemical industries. Among them some large and medium-sized the jaw crushers are the main products. Especially in designing and producing large jaw crusher, we has been a leading level at home and abroad. Try to use the advanced design tools of kinematics and dynamics simulation to have a rapid development of the new jaw crusher and to have a simulating optimization design of the mechanism design parameters, which greatly reduce the workload of the simulation design, shorten the product development cycle and improve the reusability of the simulating model. To optimize the jaw crusher by the use of simulating technology, the main task is to optimize the feeding, discharging horizontal and vertical stroke and stroke characteristic coefficient of a jaw crusher.

Computer simulations are used in many fields, including science, technology, entertainment, health care, and business planning and scheduling. With this high technology, we believe that our mining equipments will get better performance.
