The Development Progress of Global Vibrating Screen

Foreign research and screening machinery production had begun from the 16th century, with the development of industrial, the screening machinery applications demand increase greatly , so that it has been developed rapidly, until the 18th century ,the europe experienced the Industrial Revolution, screening machineryresearch reached a higher level.
The experts has found that the screening machinery has mainly gone through three stages:
The first stage, after the liberation,  vibrating screen is mainly the introduction of the former Soviet Union, a replica of Soviet design and manufacture of circular vibrating screen, linear vibrating screen hanging. Successful imitation of these screening machinery, to meet the demand for domestic production, and also trained a number of technical personnel have laid a solid foundation for the development of screening machinery in China.
Second stage: the 20 years from the 1960s to the 1980s, China successively self-developed and produced a number of excellent vibration screening equipment, such as hot and cold griddle series of coal with uniaxial linear vibrating screen series, self-synchronization, and so thick probability Sieve series.
The third stage: after the 1980s, as China's rapid economic development, constantly improve the level of science and technology as well as manufacturing, research and development of screening machinery has entered a new milestone, and made a series of encouraging results. Heavy production of well-known domestic enterprises mountain climbers circular vibrating screen has won the praise of many customers at home and abroad, but also the first in the country to provide customers with the heavy industries of the whole production line of crushing equipment
since the vibrating screen equipment birth, over a long period of development, it has been in continuous improvement and growing range of screening materials, some wet and the difficulty of screening materials, shaker difficult role to play, but after a Shanghai Hill Kai machinery Manufacturing Co., Ltd. technical staff have been efforts, Hill Kai vibrating screen has been screening all kinds of materials and wet materials dry sieving.
The main advantage of the vibrating screen are as follows :
1. Duo to the screen box vibrates strongly, the phenomenon of  material clogging the sieve is reduced , sieve has high screening efficiency and productivity.
2. The structure is simple and convenient, replace the screen surface is convenient .
3. Screening materials energy consumption per ton is less .
Mechanical structure
Vibrating screen is generally composed of the vibrator, screen box, supporting or hanging device and transmission parts.

Relationship Between Technology and Building Waste

With the accelerated pace of Chinese modernization, a lot of construction wastes are produced, Disorderly dumping phenomenon can be found everywhere ,it is understood that the garbage dumping will not only take up a lot of land, but also serious pollute the environment, the accumulation of a large number of construction waste will destroy the soil structure, causing the surface settlement. In addition, the building construction waste glue, paint, paint or difficult biodegradable polymers containing harmful heavy metals in these wastes were buried in the ground, will cause groundwater contamination, direct harm to surrounding residents life.
With the continuous advancement of science and technology, the value of construction waste(such as the waste produced by hammer crusher, sand making machine) was excavated, according to experts, the reason why it is called the construction waste is that  these wastes are not effectively subdivided processing. Construction waste are actually change the physical properties of the building materials, the event that the classification and use of construction waste will likely become a gold mine in the eyes of the vision of building materials. Is true that there are some companies and even individuals began to turn its attention to this "gold mine".
Currently, construction waste resourceful utilization has already gotten the attention of the national people , during the two sessions, the members have proposed the Construction Debris legislation, strengthen the management of China's urban construction waste. According to Mr. Zhengzhou Dingsheng Engineering Technology Co., Ltd. engineer: "construction waste after the initial cleaning, sorting out recyclable steel and wood, then masonry, cement concrete blocks broken into aggregate after the height of construction waste disposal equipment R & D, After screening, to remove impurities, the formation of a certain size requirements of building materials. "

It is reported that the applied scale of recycled aggregates  is wide,they can be used as wall plastering materials, planting soil Backfill materials, brick-making industry, recycled concrete aggregate and recycled.

the recycled aggregate brick can be idvided into the   following kinds: the ground material eco-permeable bricks, pouring permeable brick, the permeable Road tooth brick three ecological permeable bricks are widely used in square, sidewalk, slow lane, open square, garden , slope protection, protecting group, highways and overpasses.
Meanwhile, planting soil regeneration is carried out   through  the construction waste sorting, and then crushed into powder, sludge as a raw material, add other kinds of wastes, including sewage treatment plant sludge, wineries and food plant residues, peat soil trace elements, according to the proportion of a certain quality, stirred by mixing together, in addition to the natural characteristics of the soil, with high fertilizer efficiency, breathable and water retention these characteristics.

Necessity of Pursuing Excellent for Crushing Industry

With the rapid development of the social economy, the construction of the city is speed up , in the reform and innovation in the market system, every aspect of the community to achieve steady development. A transition period, not too fast nor too slow, to combine the resources and environment of the society as a whole, and to develop an appropriate set of options. Goes something like this bird in a cage, Guan Yu can not Zhang Fei; life skills on people, Pig needed Wukong. Mean to constantly break the shackles of institutional reform and innovation, and a taste of the future direction of development, but also continue to strengthen risk management. In such a new kind of social environment, it is also to promote energy conservation.
Our company-as a crusher industry leader, and how to adapt to the pace of the times, the trend of the times, how do innovation and development?
The above problems are mainly reflected in the following aspects:
First . Product quality and security, due to the crushing machine widely used in many industries ,the requirements of the crusheris also increasing . Since we all know that according to the feeding and nesting size, the crushing operations are often divided into coarse crushing, medium crushing and crushing. Must be tough crusher performance, high frequency of use, smooth operation and fast, long life cycle, will not easily be eliminated.
Second, product innovation, crusher in order to improve competitiveness in the industry must be innovative, the mountain climbers Heavy done this, and done very well, with excellent quality, technical skills, dedication and technical personnel, advanced technology and equipment to improve the overall performance of the crusher (such as the impact breaker, hammer crusher), on the basis of the original, delving into the technical parameters, the survival of the fittest, the crusher step-by-step.

Bright Development Future of Crushing Industry

The earliest application of crusher is just limited in the mining industry, along with a better understanding of it as well as technical advances, the crusher industrial application range is very wide now , such as the process of vehicles scrap cars or electrical appliances, if matchedsorting equipment and conveyors are equipped , it can be easily automated handling and processing of scrap various industrial products, recycling of steel and non-ferrous metals and non-metallic material available.
As to the dominated crusher in the world, above nearly 7% are developed on the basis of the  United States Newell products , which is more representative of Germany Lindemann, Japan's Fuji and China mountain climbers Heavy. Since the successful development of new crusher in Europe in the 1980s, the manufacture of the crusher structure design, manufacturing processes and materials continue to improve and improve. Such as the German company O & K new impact breaker machine, made a special design of the crushing chamber, rebound, metal ore material may pop up. This is also the foreign crusher application characteristics, paid great attention to the composition and structure of the material.
With the rapid development of the domestic economy, crusher industry's status in the economic and social  are also rising,which has also become essential in many industrial production  . We all know that the crusher is widely used in mining, metallurgy, building materials, road, railway, water conservancy and chemical industry and many other sectors. Common crushing machines are winnowing mill, hammer crusher, impact breaker, roll crusher, compound crusher. Jaw crusher (jaw crusher), having large crushing ratio, uniform particle size, simple structure, reliable operation, easy maintenance, operating costs and economic characteristics. PF-I series impact breaker can process materials side length is 100 to 500 mm, the compressive strength is up to 350 MPa, great crushing ratio, cubic particles advantages of material was broken; PF-II series impact breaker machine, suitable for crushing hard materials, such as cement crusher, with a production capacity of the material advantages of small particle size.
When dealing with a variety of metals, non-metallic mineral raw materials and construction materials in the production process, in order to improve the efficiency of the grinding operation, to achieve energy saving and emission reduction targets at home and abroad have developed various types of crushers, such as a hammer, to fight back type, the fastest growing anti-vertical shaft, especially hammer crusher material uniformity, high efficiency, simple structure and light weight, easy operation and maintenance.
Duo to a variety of reasons, the foreign crusher industry develops slowly  since the 1980s,   due to less investment  in the home industry, there have not much development, making this market appears blank, less new equipment, the supply can not meet the demand of the market , so the developemt future is broad.

Problems of the Crusher Accessories Production

In China, the development of wear foundry industry shows the situation of multiple small workshop enterprise and without leading enterprises, combined with the current state support for the project and the future development the field prediction , the wear-resistant castings enterprise development of our country is woeful. According to expert analysis, the wear-resistant casting industry in China has  the following mainly problems:
1, the confidence  crisis  between customers and manufacturers of the foundry industry are gradually increases. There are many well-known wear-resistant casting manufacturers reflect that many customers consulting accessories would ask such a question: "Your hammer is cast or forged?" As we all know, casting hammerhead is wearable than forging hammerhead , casting the hammerhead price is slightly higher, but the life of forged hammerhead 2 times and more. Therefore, some unscrupulous manufacturers to take advantage of the customers of the casting the hammerhead and forging hammer to discern common sense weakness, forging hammer to flicker customers, and earn high profits, resulting in the lack of trust  in the entire casting industry  .
2. Many manufacturers can not produce wear parts such as  hammerhead production by themselves , most of them  purchased from the pruchasers , but advise customers that they are able to produce, and then pocketing the difference. A cement plant in Zhejiang work a few days ago from a factory in Zhengzhou processing batch DPC2022 high manganese steel hammer found in the use of the hammer hammer with its former appearance or wear life without distinction, the only The different procurement manufacturers and price is different from the original has been purchasing from a factory in Shanghai hammerhead price than processing hammerhead per kilogram over two money expensive and salesman, and later happened to mention it, they would understand, originally a factory in Shanghai is simply not able to produce casting hammerhead, has been procured from a factory in Zhengzhou, pocketing the difference.
3, there are little plants which can do the rotor repair .  Good crusher need to have the excellent rotor, the rotor is the core part of the crushing machine, once the rotor breaks, the entire production will not be able to operate, and the crusher rotor replacement is a larger expense, many manufacturers will choose to hammer plate The end disk cracking rotor surfacing repair. Especially Fujian, Zhejiang region due to the materials and working conditions, crusher rotor repair business more, however, in addition to our company, the domestic companies which is able to undertake the crusher rotor repair business are very few,and far from satisfying market demand.

The Application Field of the Mechanical Sand

In recent years, the qualified natural sand resources are on the less , so the artificial sand gradually became the main source of construction work . Currently, our Beijing Olympic project, Xiaolangdi reservoir Baoquan reservoir, Hongqiqu reservoirs, Gezhouba Tianwan River Power Plant, these key national projects all use the artificial sand to prepare the concrete, and both its construction sand and gravel bone material strict audit and inspection. In the existing engineering practice, the preparation of artificial sand from C10-C70 ordinary concrete and pumping concrete, configure a span prestressed concrete beam whose length is 64m.
However, if the mechanism of sand does not meet the requirements, the construction of key projects, housing, highways, high-speed railway will appear a variety of engineering quality problems, so as a mechanism of sand production enterprise, responsibility must be the production of high-quality qualified mechanisms of building sand sales to the market, prepared by high-performance concrete used in construction, so can largely avoid the bridge tatami floor back down "event, visible, high-quality artificial sand can configure high-performance concrete to increase the life of the housing, roads, railways and other infrastructure projects and key construction projects.
What problems should we pay attention to when we prepare the high-quality sand ? In the crushing system of sand making production line, the traditional simple jaw breaker, cone crusher, fine jaw breaker can not meet the requirements of the the senior architectural spaces materials, because basalt gravel in flakiness and the internal cracks gravel contents are too high, production mechanisms sand quality are not good too . So, to produce better quality mechanisms sand ,the counterattack crusher must be used as a secondary crusher or sand making machine as the last one broken shaping. Generally lagging behind the entire domestic Sand production technology, the lower the yield, the higher prices, so choose  hammer breaker is the most common, such as: Shandong, Hubei, Inner Mongolia, Gansu, Guangdong and other regions, and these market gravel machinery, sand production line equipment manufacturers, many kinds of hammer breaker our company produced have the features of  advanced technology, stable equipment performance and large market share . A lot of sand and gravel production enterprises use the configuration sand production line of our company , it is true that the sand production efficiency is high,the mechanical sand podwer produced by this machine is low, gradation and quality are super .

Unique Advantages of the Rock Crushing Plant

Main kinds of rock crushing plant are follows: pebbles sand making production line, granite production line, limestone production line, stone crusher production line, with the rapid development of regional economic construction, industrial construction, infrastructure construction, high quality of artificial sand required area is very large, our company grasp   market opportunities, provide excellent services to the  large and small gravel companies across the country, and bring them more profits and wealth.
The sand production equipment is more refined, specialized, high-performance .a variety of ore resources distribute over across the country , such as limestone, iron ore, granite, basalt, river pebbles, pebbles, diabase, etc., because of their different properties such as hardness, humidity characteristics, the corresponding gravel production lines are more and more refined, the targeted crushing equipment selection is also growing,  according to the  ore resources features customers required, investment scale, site characteristics ,our company select the process line target the customers' configuration, so that the different sand production lines can achieve the purpose of most reasonable, economical utilization.
2. The artificial sand product specifications are diverse to meet the different applications needs. Construction requires the particle size of gravel and sand are different , such as 1-3,2-4,3-6 and the other specifications, the PCX sand making machine our comapny produced  can produce different specifications qualified mechanism sand products , all of them  meet the needs of different construction applications.
3, The investment is relatively small, the cost recovery period is short, the  return rate is high  . Such as a sand and gravel production line whose daily output is 5000 tons, we only need to invest 15 million yuan , and from start building to put into production items, only 100 days duration will be able to make a profit producing benefits. The benefits of these advantages and benefits quickly are fuly confirmed by the long-term rock crushing plant experiences of our company,
4, Energy-saving and low consumption, low noise, more environmentally friendly. Accompanied with the rapid developmetn of economic construction, regional industrial development, the corresponding result is the deterioration of the ecological environment. energy saving and environmental protection are increasingly being paid attention by the government , enterprises, social , compared to the same kind products, the artificial sand production line our company produced not only have the advantages of excellent crushing rate, high production output, but also pay more attention to the environment friendly design, we adopt the totally closed design, reduce noise, install the dust removal devices,and  really achieve the purpose of  building green artificial sand production line.

Significance of Vibrating Screen in Production Line

Cement production line vibrating screen: As the name suggests, it is a cement production line vibrating screen for screening (vibrating screen), in the cement production, we need to first crush the mature materials to 5mm by the   crusher, and then use the  mill for the next crushing . The most important is that this new process can improve output about 30%, and save electricity about 18%, so it is widely used by many cement producers. 
　　　
In order to assure that the mature materials size achieve to 5mm below, we need to select the materials whose size is larger than 5mm and re-crushing them. So the crushing machine and cement mill are necessary to equip the clinker vibrating screen, this screen machine can be used for raw material grading and screening equipment ,and also is essential in the former class equipment, cement vibrating screen is also a cement production processes of various cement packaging machine, due to high granularity level requirements of the finished product in the cement industry, the final inspection process is needed before the product packaging , cement vibrating sieve is used to screen cement powder and other materials in the agglomeration, foreign body, in order to guarantee the quality of the product.
Duo to the cement production line material strict size requirements, the level of material crushed having a direct impact on the reduction of the production costs. In the cement production line, after crushing the mature materials to 5mm below , and then sent them to the mill for the next crushing.  This can improve the cement mill station production   about 30%, saving electricity about 18% these substantial economic benefits. This new technology has been adopted by many manufacturers. In production , in order to ensure the granularity into grinding clinker, the vibrating screen are needed in the  crusher and cement mill.
According to the requirements of this process, the cement clinker vibration sieve we produced  adopted coarse and fine two layers of mesh, which having high screening efficiency, slagging, long life, low power consumption, small size, light weight these characteristics, but also because of its use of reliable installation, easy maintenance, clean up the debris and replacing the screen of the screen surface, damping spring,they  are very convenient and welcomed by users, this vibration sieve (vibrating screen) can be used not only the clinker sieve ,but also the other materials sieving.

Trend Analysis of Mine Feeding Equipment

Duo to the great importance Chinese government attaches the coal industry, Chinese coal washing career has experienced a rapid development, which both bring development to the feeding equipment industry space, but  also  the pressure of market competition. For adapting to this new trend and meeting the feeding machine requirement of the high quality ,efficient coal preparation plant, we suggest the following development trend:
[1] Emphasis on fundamental research,  strengthen research management. Basic research provide the basis of optimizing   product structure, improving   quality and reliability, reasonable selection and formulate  , and   promote the application of new technologies , new product development.
[2]  Accelerate the automation of coal preparation process monitoring and control technology research. Coal preparation machinery automation is the essential path to improve labor productivity,  ensure the safety of operations and reduce coal preparation costs  . Despite the  history of automation technology application is long,  there has been some technical imperfections, the introduction and application of automation technology in coal preparation plant is  also relatively slow. In today where the computer technology, sensor technology and artificial intelligence   develop  to a certain level, the feeding equipment automation process will be accelerated.
[3]  Perfect the existing equipment. Which is similar to the other industries(such as sand making machine industry), the application of modern technology in the feeding equipment gradually grows,   but  the existing feeding equipment will continue to use, and   continue to tend to perfection, because if we use the new technologies or the old-typed equipments only ,it is impossible to obtained marvelous results.
[4] Strictly control the environmental pollution. Environmental pollution is mainly caused by the feeding equipment noise and dust, so the focus of controlling environmental pollution is to control it in the limits prescribed in the national standards, and should try to applicate, research this new technology as long as possible, put the pollution to the minimum.
Large feeding equipments have the advantages of high efficiency and processing power, but the equipment's large-scale, standardized   and high reliability is also  its development trend . In recent years, the large-scale feeding equipment in the domestic coal industry has been widely used, there are certain issues, such as the technical parameters of the device called extensive,   affect the actual use, which requires further theoretical research and improvement, so it is best to further research and improve the current theories,only in this way, our feeding equipments can develop better and better.

Reason of the Crusher Dispose Dust Improperly

The crusher dust seriously affect the production capacity of the crusher (crusher) and the health of workers, facing the large amount of dust  crusher produced, our technicians provide professional crusher dust problems for our crusher customers , I hope it is helpful to you.

What problems the crusher dust improper dispose will cause ? The following is detail explanation:
◆(Crusher)the general baghouse filter area of crusher is small, ventilation is generally inadequate , dust cover and crusher cavity are difficult to form a slightly negative pressure, therefore, the dust of the working environment is large,  which is not conducive to breathing.
◆ Precipitator dust enter into the pipeline, the system resistance is increased at the elbow of the inlet tube , the bend parts are susceptible to  be wearied and clogged by the dust. If we adopt the screw conveyor and sub-grid transport wheel baghouse to collect dust ,the power consumption will increase, mechanical maintenance workload will increase too; we often  need to demolish the under sub-grid wheel feeder, if this situation lasts a long time, the under feeder flange will leak air ,it will exacerbate the ash bucket air leakage.
◆ When crushing materials humidity is high (after raining or the materials be caught in a shower) ,the dust particles be sent into the precipitator is larger than the dry crushing materials, the bag-type dust collector is easy to be pasted,  the under feeder is easy to be jammed,  this will bring about the significant increase of the bag-type dust collector ventilation resistance , and the ventilation capacity is decreased, of course the dust problem will be more serious .
◆ In the process of the materials fall from the belt conveyor, the air and the material went together into the closed dust cover, the dusty air spread to the outside of the cap through the crevice and orifice hood walls ,which pollute  the environment. In addition, due to incorrectly set of the belt-corner dust point , open and stop of the precipitator is almost no impact to head dust of the lower belt conveyor . Therefore, since the 5th rock crushing machine was put into use , this dust collector almost does not work, the upper belt conveyor has been in the diffuse dust.
◆ The failures of baghouse and supporting parts are more, which not only affect the normal dust disposition, but also increase the equipment maintenance workload.from the view of equipment maintenance statistics ,the  spare parts' poor quality are important reason of equipment failure .
In order to reduce the dust caused by the crusher housing air leakage , in the actual production, people often water the materials at the mouth of crushing ,  its result is intensify the baghouse filter bags paste and  the under feeder blockage. Because  people often  conduct intermittent clean to the baghouse , when the precipitator works normally , the division round air leakage is  a question that should not to be neglected.

Design Knowledge of Crusher Hammer and Disc

Although hammer crusher is a mature mining crushing equipment, for its design, we must not sloppy. The following is the knowledge introduction to the design and calculation of crusher's hammer and disc:
◆ The hammerhead design and calculation of hammer crusher
Its design mainly refers to the structural design. As the hammer head shape, quality, materials are very influential to the crusher production capacity, Especially the shape to the quality distribution, full use of the materials. As to the more detailed discussion on the hammerhead structure design and related improvements ,you can see it in the topic. In short, hammer is the main working parts. Its Shape, structure design have far-reaching economy effects to their work ability , the production capacity of the entire machine.  Hammerhead shape is generally divided into light, medium and heavy these three types. This model of hammer crusher refers to the medium-sized hammer design,and related calculations.
The hammer crusher can also use the high manganese steel as its design materials . Hammerhead material selection problem is a very critical issue to improve its abrasion resistance. The choice of material depends on the working conditions and requirements of the working parts. Because the  crusher always crush the limestone these medium hardness materials. People usually use high carbon steel to forge or cast. adopt high manganese low alloy steel, some is coated with appearance Carbide. Some high chromium cast iron, its wear resistance is several times greater than the high manganese steel hammer . As to the choice of materials: you can see the part of topic-improve wear resistance hammerhead specialized exposition.we don't described in detail here, In short, hammerhead choice of materials is not only related to the working life of the hammer bit, the production capacity of the machine, production efficiency, and is also related to various aspects of economy.

◆ Disc structural design and calculation of the hammer crusher
Each pin requires 8 hammers. If the disc is used suspension hammerhead,then it requires a total of nine discs,this depends on the design requirements. Two discs on the sides, the common feature is that one side is equipped with the locking nut, the other end is positioned by the shaft shoulder. The used nut is GB-812-85 , so that each disc is evenly distributed six round hole,we can use 6 pin shaft to suspend hammerhead,  The size of the disc depends on the diameter of the rotor, the size of the diameter of the rotor is the basis of the disc design size. Therefore,we can know the rotor diameter is 800mm according to its model, the disc size value is in a certain range. the circular hole size is approximately equal to the hammer hole size.

Operation Precautions of Jaw Crusher

Jaw crusher should be installed above the concrete foundation,and plus  skids or rubber to reduce vibration when working.
Jaw crusher's (jaw crusher) operation: the correct operation of the crusher  is one of the important factors that guarantee the crusher works properly, improper operation or negligence in the operation are often caused equipment and personal accidents. Correct operation is to  follow the rules strictly.
The preparatory work Before starting : careful examination before starting the crusher, the check contents are: crusher tooth plate wear situation, adjust ore discharging mouth size, whether the ore crushing cavity having ore; if large block ores exist, we must remove them,; whether the connection screws loose; whether the pulley  Flywheel protection cover is intact; whether the tightness of the triangle belt and trolley spring are suitable ;whether the lubrication system is intact; whether the electrical equipment and signal system are normal or not.

Handling Precautions of jaw crusher (jaw crusher):
1, After starting, if the crusher makes unusual beat, we should stop automatically turn, and restart after identifying and eliminating the ills .
2. When starting, Crusher must no-load , when the automatically turn is normal, we can start the ore-discharging equipment , the ore be fed into should be gradually increased until the load is full.
3. Ore discharging Should be uniform , ores are not allowed to be packed with the crushing chamber; the  maximum  mine size allowed should not be larger than 0.85 times of the ore discharging mouth size; while feeding ore, we should ban the anti-mine iron and other non-HSBC crushed materials into the crusher; once we found these non-broken materials go through the port of discharge, we should immediately notify the belt transporter in time to prevent serious equipment accidents of the next crusher , such as the impact crusher and hammer crusher）。
In the operation process, we often have to pay attention to the situation of lump ores stuck to the mine mouth, sometimes use an iron hook flip or application-specific tools when operating, but not by hand to avoid an accident. During operation ,if the ore feeding are too many to choke the crushing chamber, do not stop the crusher ,but should stop ore-feeding, we should start the ore feeding machine after dealing with the ores in the crushing cavity. during working, the operator should conduct check regularly, according to to see, hear, touch and other methods to observe the various components situations of the crusher position and bearing temperature, the bearing temperature must not exceed 60 ° C, we should not immediately stop when the bearing temperature is too high, instead,we should take plus large amount of oil, forced ventilation, water-cooled these methods to reduce the temperature.

Crusher Technical Advantages Analysis

 ◇ Impact crusher (impact crusher) can effectively handle the material having a large amount of moisture, which can prevent crusher clogging.
When dealing with the materials having excessive moisture, impact crusher's feed chute and counterattack board can be equipped with a heating device to prevent the adhesion of the material. Impact crusher is not required to be equipped with the bottom screen ,it can effectively prevent clogging. Hammer crusher can not prevent the bonding of materials by heating, and shall be equipped with the bottom screen, this increase the possibility of clogging.
◇ Impact crusher is applicable to both soft materials and hardness materials.
The plate hammer is firmly fixed on the rotor by the mechanical clamping structure , when it moves with the rotor rotates,a great moment of inertia is produced . Comparing to the hammer crusher (hammer was hanging), impact crusher rotor has greater momentum, and suitable for crushing harder materials, at the same time, the energy consumption  is lower.
◇ Convenient and flexible adjustment to the crusher discharge size, wide range of adjustment.
Impact Crusher can adjust the particle size through a variety of ways, such as regulate the rotor speed, adjust the counter plate and the grinding chamber gap. The gap adjustment can be adjusted by mechanical or hydraulic type, hydraulic adjustment system can easily complete the adjustment of the gap through local operating button or fortune control system. While the hammer crusher regulating discharge size can only be achieved by replacing the bottom screen(comparing to the impact crusher，but not cone crusher).
◇ Impact crusher (impact crusher) wearing parts wear rate is smaller than hammer crusher, the metal utilization is higher .
Impact crusher board hammer wear area only appears on the looking materials side. When the rotor speed is normal, feed plate hammer will fall on the surface ( attack area), the plate hammer back and sides are not to be worn. Even the looking material side wear very little. And the bottom of the grinding rod is also very easy to replace.the metal utilization rate of impact crusher board hammer can be as high as 45% -48%. While the hammer of the hammer crusher was hanging, wear and tear occurs in the upper, front, rear and side, comparing to the plate hammer, hammer wear more serious, hammer metal utilization is only about 25%. And the rotor body itself may also be subject to wear. Hammer crusher wear seriously affected, and the replace work of sieve is also more complicated.
◇ Impact crusher spare parts are easy to replace, and the maintenance costs is reduced.
Crusher rotor is only installed six plate hammer, using the HAZEMAG company provided special tools ,we can easily replace the board hammer,  replace a board hammer just need one shift time. The bottom of the grinding chamber grinding rod replacement requires only ten minutes ,which can greatly reduce the time and cost of repair and maintenance.
