Any industry, any equipment is anticipating high efficiency and low cost, especially for expensive construction machinery industry. The enterprise profits are anticipated more and more. Construction machinery industry is not only important to promote the people's livelihood relies on the construction, but also the achievement of the industry, rapid development of effective protection, so the development of construction machinery industry is also a priority in the other. That is why the 'high efficiency' has become the measure an important indicator of construction machinery products, but now, construction machinery, 'efficiency' is still up in the high-energy-based implementation, which also led to our construction also in large amounts of energy, manufacturing a wide range of pollution. How to reach both efficiency and energy-saving in construction machinery industry, which should be taken into consideration.

Construction machinery industry is a combination of technology, capital and labor, in recent years as China's construction machinery industry, the increasing size of the market expansion and our continued efforts to strengthen infrastructure, economic market segments made higher requirements, including not only technical, intelligence, including energy saving, environmental protection and other factors. Nowadays, energy saving has become a hot topic in our society, it seems to be no energy saving construction machinery industry is also related to development of the market to catch the express train, the urgent need to efficiency, energy saving, green, environmentally friendly direction of transformation. Many energy saving concept has also been applied to construction machinery products, such as 2009, in the country for the first time introduced the concept of hybrid energy-saving machinery to study, and developed a new type of China's first jaw crusher, crushing than the traditional machine 30% energy efficiency by 25%. It also confirmed the construction machinery enterprises are moving toward the goal of energy saving efforts.

After 50 years’ development, China construction machinery industry forms an important industry which produces products of 18 categories, more than 4500 specifications and types, and meets the basic demand in domestic market and has quite a scale and flourishing development vitality. Although there are some performances, but still in its infancy. China's construction machinery industry is currently facing energy conversion efficiency is low, the operation is backward, and serious environmental pollution problems, which gives the energy saving industry has posed a serious challenge. At present, China's primary energy consumption has more than 3.2 billion tons of standard coal, crude oil dependence on foreign imports to reach 55%. Oil consumption is the main area of ​​petrochemicals, transportation and engineering machinery. Construction machinery, especially the broken machinery industry, oil consumption is an important aspect can not be ignored.

But compared with foreign competitors, China construction machinery enterprises still have some problems as follows, they are: big gap of control technology; corresponding parts( spare parts, components) non-reaching standard; insufficient consideration of man-machine engineering; less research and development input. It is the key for construction machinery industry to adjusting the product structure in the development process.

In addition, we also take into account environmental issues, the traditional engineering machinery products have been far from meeting the requirements of air quality at this stage, to long-term sustainable development, and only continuous technological upgrading and innovation that the future of construction machinery essential factor is the environmental protection industry. In addition, competition in the international market which is not often due to emissions standards, exports have been seriously hampered. From this green energy has become China's construction machinery industry, the problem can not be ignored. But we also see in the domestic construction machinery enterprises are active in-depth study of a new generation of energy saving, environmental protection equipment, more and more construction machinery manufacturers have focused mostly on 'energy-saving''intelligent' two key word.

Demand and growth rate of construction machinery products have close relation with GDP and investment scale of infrastructure construction, industry boom situation is related to the growth rate of investment in fixed assets with synchronized positive correlation. During the '10th Five Years', consumption amount of China construction machinery occupied 1.9% of the whole social fixed asset averagely per annum. The growth rate of fixed assets investment will slow down during the '11th Five Years', market capacity will expand relatively insufficiently, and the industry will develop toward rationality gradually.

Mineral resources is the most important foundation our country's economic construction and social development, it has vital position in the national economy and security. At the same time, any resource maybe use out. Todays, energy and resource expolitaion is the serious issue to talk about.

In case the supply of mineral resources disruptions, it will pose a serious threat on economic, social and national security. However since the 1990s, many mineral resources consumption growth has approximated or exceed the national economic development speed. The economic growth made a large demand of mineral resources. A resource analysis data recently shows, in 2010 ,mineral oil, gas, aluminum and iron, copper, gold, nickel, sulfur, boron, uranium, phosphorus, potassium, chromium, asbestos are unable to satisfy domestic demand, by the year 2020, The shortage of China mineral resources will be increased to 39 kinds.

Analysts say that in the coming decades, with Chinese industrialization and economic globalization, China will become the world's most important mineral resources consumption country. In the coming decades, comparing with main mineral demand in our country at present, the main mineral reserves will appear serious shortage. And mineral resources in Chinese economic and social security is decline, the paradox of resource bottleneck of contradiction is becoming more and more serious. To implement the strategy of 'going out' is dispensable, we should make full use of both domestic and international markets, to satisfy domestic economic development needs.

No modernized countries in the world can make all mineral resources and raw materials self-sufficient. In recent years, China's oil, iron ore, copper metal importing dependence are becoming more and more serious, particularly oil and iron ore. Long-term excessive dependence on imported is both economic problems and national security concerns. For the long-term development, only based on the resource security, the national security is guaranteed. Implementing the strategy of 'going out' will extend more space and wider range of areas and at a higher level participating in international economic and technological cooperation and competition domestic and abroad. Make full use of two kinds of resources, two 'markets', build all-round, mineral resources and sustainable supply system and improve mineral resources sustainable development of national economy is the issue we should concern.

For ore dressing process, there are two ways: flotation process, magnetic process. Magnetic separator is used in magnetic procell. It applies to wet magnetic separation of materials below 3mm such as the magnetite, pyrrhonitite, roasted ore, limonite，ilmenite. Also used for coal, non-metallic minerals, building materials' remove working.

Magnetic line of the magnetic separator uses high quality ferrite materials or compound with rare-earth magnet, the average magnetic induction is 100～600 MT, we can provide downstream, semi-current, counter-current, a number of different forms magnetic separator according to the users' need. You can use them in industries like mining, and smaller versions are widely-used in scientific labs to process some kinds of samples. Numerous companies make magnetic separators for assorted applications, there are some variations intended for website visitors to select from,jaw crusher, according to the application and needs. This sort of products are which is available from companies which are experts in industrial processing equipment, therefore it may be ordered completely from manufacturers, where individuals have customized needs.

An elementary magnetic separator is made up of magnet of some sort. As materials are passed below, over, through, or round the magnetic separator, it attracts undesirable impurities, pulling them out and cleansing the process stream. Magnetic separators might be ferromagnetic or paramagnetic, according to the needs, and in many cases materials will likely be passed through both varieties of magnetic separators. They may differ in proportions from tabletop separators found in labs to massive drums found in recycling facilities.

One of several common uses of a magnetic separator will be the eliminating so-called tramp metal,Magnetic Separator, undesirable iron that may foul a procedure stream. Magnetic separators may also be employed to remove materials which may damage or foul equipment, inside a pre-processing step. Separators may also be used to sort various metal, using a group of separators varying in intensity to get out strongly and weakly magnetic materials at different times.

Like other devices used in processing materials, a magnetic separator must be properly maintained and operated as directed in order to be effective. Maintenance includes clearing the separator to remove magnetic materials it has collected, along with periodically oiling moving parts. In the case of electromagnets, it is also necessary to make sure that emergency shutoffs and other safety features are in operational condition, so that the magnet can be turned off in the event that a problem develops on the production line.

There are many disasters and risks for recent years, such as earthquake, waterlog, drought, war. Along with these, global economy has in great fluctuation. Of course, one coin has two sides. There are disadvantages and advantages brought. As a result of the financial crisis, many enterprises are facing domestic and international operations, the dual crisis of survival. It also directly contributes to China's mining machinery industry, competition, and if the rest on its laurels, inert, business, living a double crisis of the event so difficult mining machinery industry. How to talent in this competition, to achieve a breakthrough? Accelerate scientific and technological innovation is the unquestionable choice.

A) Infrastructure development has brought opportunities for the mining machine

The use of mining machinery and basic facilities in areas of interest-rate coherent future, there will be a great market. Moreover, the financial crisis, China adopted a series of stimulating domestic demand and ensure a stable and rapid economic development policies and approaches, in which the State Department recently dropped into 4 trillion, 'increased security' approach, pulling the premises to the Government's new round of investment enthusiasm, ' livelihood projects 'to become the number one investment priority.

Government investment plans in the premises, the focus is still railways, highways, power plants, real estate and other infrastructure projects, which are in China mining machinery industry with close contact. This is our country's supply of mining machinery industry to develop new opportunities, but also put forward a higher request, require mining machinery industry to speed up scientific and technological innovation, progress, science and technology content, in order to compete for the future skill areas with more open markets.

B) Low-tech, impeding the pace of development of the industry

China's mining machinery in general and the international advanced level to be out of date compared to 15 to 20 years, the majority of product techniques the origin of the last century since the mid-80s imported from abroad. The domestic market, mining machinery products in the market occupation rate is less than 80%, at the entrance of the products are mostly large, precise, sharp and complete sets of very strong products, such as Shearer, large and efficient equipment, respectively, crushing and grinding equipment, full - cross-section with boring machine and other products.

Mining machinery industry, the basic technology is not strong, reform and opening up, mining machinery areas has been progress in the market for technology products as the skill level of the major roads. Looking around the world mechanical design of the development process, important thing is to stand-alone product design to the stand-alone product design process and then to complete sets of equipment designed for evolutionary process. China's general mining machinery manufacturing just completed a stand-alone product design and manufacturing, device applications, process flow design done by a professional institute, stand-alone product nature of the request process are also made by a professional design institutes and to assist in the completion of manufacturing, which resulted in equipment fabrication plant and equipment, the gap between application part. Thus, in the current mining machinery production sectors and enterprises designed to process the case of relatively thin, except in their own areas of expertise as soon as conditions are good, organized effort to enter into the role, should be used with foreign companies and national professional institute to establish a different situation combined, including the formation of groups, the Commonwealth, the introduction of technology, the introduction of qualified personnel and other measures, at least in a fight to the project on the use of integrated design approach, first to participate and then progress, and achieve win-win situation, and similar enterprises in most of the consequences of recklessly tender bad.

C) Network on the impact of mining machinery business

90 years since the 20th century, the emergence of governance in the developed country wave of change that swept a new era of industrial revolution, this is a network of economic globalization and the information tag into the Industrial Revolution, it poses an unprecedented impact on the original production methods, changes in the original business model. Enterprises to adapt to this change in the networked environment to operate governance has become the irresistible trend of the revolution, the traditional enterprise network to meet this in-depth treatment, the turn facing a new opportunity and provocation. Traditional enterprise networks have a significant impact, special is a mining machinery business, the network can not be compared with other traditional methods peculiar upper hand, China Mining Machinery Network (www.ccdrc.cn) for the supply of mining machinery business services.

However, the future of mining machinery industry will present two important strategic groups: the supply of full range of products and services, generalist-based businesses and product or market segment expert-oriented enterprises. At present, the domestic leading enterprises and transnational corporations is also comparable to the strength compared to the weak, while those who concentrate on the market in some products and the formation of core competitiveness, and to gross profit of the expert-oriented enterprises are more likely to survive in the fierce competition down. In the mining machinery industry, the new competition format, a considerable number of domestic enterprises will be the multinational production and marketing system in a link, and a small number of products and services with the core competitiveness of enterprises will likely become a confrontation with transnational corporations outstanding.

Consequently, at the new time, the future and scope of China mining machinery industry are both bright. The machinery enterprises should improve the product technologies, intensify network marketing, and promote enterprises competence and services. Todays, consumers maybe take less consideration on products price, but take more on product services and product brand. Totally, comprehensive development of an enterprise can take the advanced rank in the world.

As we learn, miners continue to die in accidents in China, Russia, America, and elsewhere. As we learn, academics and corporate apologists generate technical papers on management by a risk-based approach. We'd like to ask that: Will or won't it go bankrupt paying for the cleanup?

The phrase 'safety is built from the ground up' may seem like a cliche. But a group of mining companies is taking the message to heart with a concerted campaign to work with original equipment manufacturers (OEMs) to ensure that safety is incorporated into the design of mining equipment. The group meet with OEMs on a regular basis, typically once a year, bfinging forward recommendations for design changes to equipment in order to improve sagety. While the initial focus was on surface mining equipment, EMESRT has expanded into three other equipment areas - exploration drilling, underground hard rock, and underground coal and soft rock.

Safety risk exists along with enterprise's loss. In another word, once one mining company disaster is reported, its fame, enterprise image and finance all face the risks. In addition to this aspect, there is another risks. Thus, mining enterprise has to learn how to live with these risks. “You cannotafford to do it all, so take the risk and get the probabilities right.”

All too often these prophets of probability prevail. And equally often their statistics are proven right: something fails and somebody in the mine dies. Or worse, they are proven wrong; and something fails, and many people at the mine die. A committed mining statistician will tell you: “There is no suchthing as a risk- free world. Thus we must incorporate risk, probability, and consequence in our real-world view, analyses, and decisions. After all, we will all die sometime, the tailings will flow to the ocean eventually, and the pit will become a part of the topography.”

The fascinating thing to contemplate in the light of coal mine deaths, tailings dam failures, and oil rig blowouts, is this: What, if anything, do these recent, admittedly spectacular events, mean to other mining projects? One blogger recently asked: Can the Alaska Pebble Mine survive BP? In other words, how can one defend probability in building 700-ft high slimes dams above the salmon hatchery? In the enormity of time, any probability offailure, no matter how small, will come to pass and those baby salmon are toast.

In search of a risk-free world, in deference to the near-demise of BP, and in recognition that extreme statistics do play out, are we headed to a new mining world; one where only reasonable projects involving rich ore bodies in dry, non-seismic parts of the world proceed? Are we headed to a more conservativeperspective where the old mining risk profiles are no longer acceptable? Is mining going to be stung by the BP oil spill to avoid projects, to do better project engineering, and to try to make living near andworking on a mine as safe as commercial flight? Funny how we accept that commercial airlines shouldbe safe, but happily accept far less in a coal mine, in a slimes dam, and on an oil rig.

Open-pit mining follows the same sequence of operations as underground mining: drilling, blasting, and loading and removing waste and ore. Open-pit mining follows the same sequence of oprations as underground mining: drilling, blasting, and loading and removing waste and ore. Opencast mining is highly mechanized technological process which, due to low manpower, high production outputs and engagement of heavy-duty mining mechanization requires a very high consumption of power, spares and materials. Those facts indicate that rationalization of the consumption of power and materials requires specific attention in scientific senses.

General prognosis that deals with the development of surface exploitation of coal in Yugoslavia, along with ecological issues also covers large energy and materials consumption in this field as a strong limiting factor. Such estimation is based on the ever increasing requirements for energy. spare parts and various materials that in surface exploitation of coal are growing with increase of the physical volume of production. The complex analysis of the factors influencing consumption of energy and materials in the surface exploitation recognizes three groups of main factors such as natural. technological and organizational.

The group of natural factors covers separation of deposits, relief of terrain, coefficient of overburden, physic-mechanical properties of the deposit, depth of mining, mineral materials quality and length of transportation roads. Technological factors include structural equipment design, project designs. installed power, method of excavation, loading and transportation, method of piling, development of excavated faces, useful value of mined materials and mineral processing. Quality mineral materials and the length of transportation roads can also be listed among the technological factors. The organizational factors are represented by: managing of process, qualification of stuff, maintenance of mechanization and monitoring the energy as well as material consumption. Certain open pit mines initiate the study of a series of mutually interlinked issues concerning technology, efficiency and organization of production, thus overpassing the accepted principle that the planning standards are only based on the previously achieved consumption standards. Defining the modem methods of monitoring energy and material consumption might be considered as the general scientific-research direction in surface exploitation for the purpose of decrease in overall costs and better productivity.

Transportation of overburden, within the limits of the open pit surface itself. to internal waste dump and crushing equipment is carried out by dumper capacity from 50 to 70 t, and volume of loading frame from 30 to 50 m3. Transportation of overburden to the external deposit is carried out by belts with previous crushing of material by crushers. At the present stage of exploitation, six transporters were installed, three of which being permanent and three mobile, in a total length of around 4500 m. The said transportation system also consists of below-level dump stackers and above- level dump stackers having the capacity adjusted to transporters. Coal transportation from open pit mine to crushing and separation plant is also performed by dumpers capacity of 36 t, volume frame of 26 m’. In this plant classification of coal is made depending on its market purpose.

While monitoring electric power consumption the data used refer to periodical control of such energy consumption and a comparison with the planned quantities was accordingly made, having in most cases quite a negative effect, as the adequate interventions failed when a large consumption was in question. Somewhat less complex system of evidencing was applied when monitoring fuel consumption, particularly in case of open pits having their own pump stations. Rarely, complex factors influencing the consumption of energy and material were analyzed such as the efficient technological processes and efficient organization of labor. Since recently, consumption of energy and material at open pits in Yugoslavia has become more actual.

Of course, equipment quality is also the factor to affect the energy consumption. Todays, Hongxing has many new types of coal mining equipment: VSI coal crusher, ultra-fine micro powder grinder, high pressure Raymond mill, super fine impact crusher.

Transportation exists and is seen everywhere. Some transportation costs little, while some costs much just like machinery transportation. And also some transportation is complex. Facing so many types of transportation, there are various system to deal with them. As to coal and ore transportation, a new type of transport system appears.

The new system is now available that could bring incredible benefits to the mining industry. The system can potentially eliminate the need for constructing new railways to transport coal / ore from the mine to the port (or other destination).

The great thing about it is that the same system can also be used to transport workers to / from the mine, in many cases eliminating the need for expensive fly-in-fly-out (FIFO) transport. The system can also be used to transport supplies to / from the mine.

Another major benefit for the mining industry is that this system can eliminate the need for expensive port loading infrastructure because the transport modules can load directly into ships.

This system is also an answer to some of the criticism received from the environmental movement. The system can be installed with minimal earthworks and can cross sensitive environmental areas with minimal impact. The system is also extremely fuel efficient.

The cost to install the system is about half the cost of installing a conventional railway line. If you combine the savings from line construction and eliminating the port requirements, the savings amount to hundreds of millions of dollars. In some cases, this can mean the difference between proceeding or not proceeding with a new mine development.

Problems are anytime, but ways to solve them are developed by human's intellegence. With advanced technology, any difficulty can be resolved and performed successfully.

In mining industry, milling machinery plays an important role and there are various kinds to meet different working environment, such as 3R or 4R Raymond mill, ball mill, micro-powder grinder, roll mill, rod mill and so on. Starting milling, should check whether all the maintenance doors closed tight, check the crusher jaw plate gap is in line with the feed grain size, adjust the analytical engine speed should reach approximate finished size requirements. And press to start the order.

1. starting basket bucket elevator;

2. activate the jaw crusher;

3. when there are material silo, start analysis machines;

4. to start the air blower (air load to start until the normal operation after the load);

5. start the host, start the host instant starts electromagnetic vibrating feeder.

Grinding work shall be started at this time. Simple sequence of operations are as follows: Start: enhancing machine crusher → Fan → → analyzer mainframe → Feeder. Shutdown should be in the following order the closure of the machine:

1. first close the feeder to feed material;

2. about one minute after the cessation of host;

3. blowing the net residual powder after the cessation of sub-blowers;

4. the final closing analyzer.

As to the tips for maintenance, there are some suggestions below:

1. Milling machine using the process, there should be regular staff responsible for the custody of the operator must possess a certain level of technology, milling machines are installed before the operation is to conduct technical training for customs officers must make to understand the principle of mill performance, familiar with operational procedures.

2. For the mill to work, there should be equipment 'Maintenance of the safe operation of systems' can ensure the long-term safe operation of mills at the same time have the necessary repair tools and accessories grease.

3. Mill use for some time, maintenance should be carried out, while roller grinding ring Blade repair of wearing parts such as replacement roller device in use before and after the connecting bolt nut plug should be carefully examined whether there is loosening , lubricating oil is to add a little grease.

4. Roller devices of the time more than 500 hours or so to replace the roller when the roller kit must be cleaned of all rolling bearings, damaged parts should be replaced, dispensing fuel or butter can be used to manually hand gun.

Milling machine in the normal working hours are not allowed to refuel at random, to ensure safety in production and milling machine in any part of the unusual noise, or a sudden increase in load should immediately stop inspection, troubleshooting, so as to avoid a major accident. Then continued to boot mill must be removed within a more than expected, or when the current boot is too large, the impact starts.

Raymond Mill mainly by the host, analyzers, blower, finished cyclone, cyclone powder and air tube. Among them, the host from the rack, inlet volute, blade, roller, grinding ring, cover composition.

In the working process of Raymond mill, how is the winnowing process? After grinding the material, fans will be blown in the White case, the blowing powder, placed in the grinding chamber through the top of the analyzer for sorting, fine through coarse material into the grinding raymond mill chamber and re-grinding, compliant with the fineness airflow into the cyclone collector, collected and discharged through a powder outlet, is finished. Airflow from the top of a large cyclone collector tube back into the return air fan, air duct is circular, and in the flow under negative pressure, circulation air duct to increase air flow between the host partly by the exhaust fan and exhaust pipe into the small cyclone collector device, for purification.

Correct operation is important for a machine, such as jaw crusher, cone crusher, impact crusher, ball mill, sand washer, belt conveyor, and the maintenance is also useful to extend the machine's life. Just taking Raymond mill as an example.

1. Non-metal block into the machine, otherwise it will damage the grinding roller and grinding ring, and even center hanger.

2. The feeding should be uniform, not suddenly much less ignored. Excessive feeding blocked duct will reduce the yield, easy to burn out the motor, feeding too little will affect production. Feed size: hard materials less than 15 mm in diameter, preferably, soft material for the 20 mm diameter, non-bulk material added to the machine.

3. Air volume control: the intake pipe is located on the blower air volume control valve, generally open to the maximum position, according to fineness, yield requires an appropriate adjustment. Located on the exhaust pipe outlet exhaust valve, transferred into the feed opening can be no dust emitted. Air volume is small, thin high. It should be noted, the wind is too small, the host is easy duct below the sediment material, please adjust.

4. Fine adjustment, based on the size of the material, hardness, moisture content, the proportion of different degree of processing are different thickness, can be adjusted at the top of the analyzer, high speed, fineness, low speed, low fineness. Improve the fineness, the output will be reduced accordingly, if it is mainly the fan speed when debugging, the user can flexibly.

5. Ring roller raymond mill scrap the limit, the minimum remaining wall thickness of not less than 10mm.

6. Stop, stop feeding, the system still continue to operate, continue to make residual abrasive grinding, about a minute, turn off the main motor and the motor analyzer, stop grinding work, and then stop the fan motor to blowing off the powder residue.

What does the gold mining brings when we talk about business? It means profit. But what does gold mining brings when we talk about nature? It will mean disaster… because doing the gold mining operations will turn the whole place into a desert without any trees to grow and without any animal to live. The gold mining operations will really change the natural resources of water shades and even lose the chances of safety living to those who lives at the low landareas of the gold mining operations. Especially the farmers who are usually been making the rivers as their source of water to take care of all their flocks and animals. Mining equipments (jaw crusher, impact crusher, ball mill) usually the gold mine operations will bring a great fight and arguments between the environmentalist and the side of the mining operators or mining company because all they up to is to take the gold without thinking the bad results that the mining could brings as long as they can get the gold deposits in that certain place. But no matter how the environmentalist will opposed the gold mining operations, it will only be heard for a while but it is always the gold mining operators who will win. Because what would be the possible opposition that the environmentalist will use to opposed about nature, the mining company can present their equipment that will serve as nature friendly according to their own evaluation. But if you will really try to look at the result of every mining operation it will only really damage the natural resources of the place because when the gold mine operations are done they will evacuate from the place and live it in a deserted life and nature. What they are going to live in that place is a totally damage place of the mountain that you will never see what it was before.

Gold mining companies are fully equip with all the heavy equipment (Raymond mill, belt conveyor, cone crusher, hammer crusher) they need to continue the gold mining operations, to bring profit for the company but not to protect the nature and the people who are living after the place where the gold mining been doing its operations. Gold mining are using dynamites to brake the mountains. As a result floods will happen anytime and all the time. When the rainy days comes, floods will risk the whole place especially the low land areas where the waters are going to overflow and damaging the huge amounts of farmlands in the lowland areas that will even kill people who cannot manage themselves from the rushing flood of water coming from the high lands. And it is very sad to know that even if these things are happening over and over again wide range of mining operations are still going on with their operations until they are done and live the place to find another gold mine explorations.

Crushing productivity is an important technical and economic indicators, the broken particle size is guaranteed under the premise of crusher manufacturers and users are required to maximize crusher productivity, thereby improving

Crusher user economic benefits. Especially in recent years, as the global mineral depleted, but in expanding the scale of mining, crushing grinding through a sharp increase in ore processing, thereby increasing productivity is more important crusher. Therefore, the crushing machine productivity must be as multi-objective programming model is an important objective function. PE jaw crusher, VSI impact crusher, vertical mill are useful.

Jaw crusher broken wall cavity shape is formed by rolling acetabular wall and work space. Cavity design is good or bad, on the economic and technical indicators crusher (productivity, energy consumption, broken particle size and grain shape and the broken wall and rolling wear of acetabular wall, etc.) have a significant impact. Therefore, the cavity-shaped performance as the jaw crusher to be multi-objective programming model is one important objective function. Quality based on a fixed principle, according to the broken machine performance parameters, can solve the ideal curve laminated crushing chamber shape, but because of the broken layer crushing chamber work states and crusher to the nip angle, the discharge opening and the crushing chamber height requirements and standards restrictions, the actual curve obtained laminated cavity-shaped crusher often only approximating the ideal curve-shaped laminated crushing chamber. Layer of the crushing chamber can be broken by the amount of material equivalent standard deviation as a measure of crusher cavity design of the pros and cons, so the crushing chamber through the broken layer equivalent material standard deviation as a measure of the amount of performance-shaped cavity of the objective function.

Crushing machine crushing grinding product size is an important economic and technical performance indicators, broken particle size will have a direct impact on the economic benefits to the user crusher, the crusher performance reflects the pros and cons. Broken machine users, to meet the productivity requirements of the crusher premise, are expecting better quality of fragmentation products, thus crushing the product size distribution as a jaw crusher to be multi-objective programming model is an important objective function. In production practice, generally use less than the crusher closed side of the nesting population broken broken products, the total percentage of products that calibration marker size as a measure of quality of technical indicators broken.
