Impact Crusher is mainly used to crush many kinds of large, medium, small materials such as rock or stone whose side length is less than 500mm, and compression resistance should not be more than 350Mpa. The impact crusher is widely used in hydroelectricity, highway, artificial rock, stone and sand, building material, etc.
Working Principle of Impact Crusher:
When the impact crusher works, the motor drives the rotor rotate with high speed, on the rotor where installed the hammers. When the materials get into the area which the hammers effect, under the impact function of the hammer at a high speed, the materials are thrown to the impact device above the rotor continuously. And then the materials are rebounded from the impact liner to the area where the hammers effects for being recrushed. The materials from large to small all to be crushed at the impact chamber repeatedly. The process will not stop till the material are crushed to the required size and then discharged from outlet. 

The main features of impact crusher: 
1.Connected with locking sleeve assembly. 
2.Final product with cubical shape. 
3.The blow bar with high chrome. 
4.Easy maintenance. Hydraulic or hand opening. 
5.Reliable operation. Impact plate with a special shape.

High Pressure Suspension Mill is a new kind of mill, which is invented with great concentration and on the basis of many years of powder processing experiences. This invention starts an epoch of high efficiency and low cost in international mining industry. High Pressure Suspension Mill can be used to grind non-inflammable and non-explosive materials with Mohs hardness below 9.3 and moisture content below 6%, such as barite, limestone, pottery, scoria. Size of final products can be adjusted between 80-425 mesh (The fineness can reach 1000 mesh).High Pressure Suspension Mill can produce coarse powder between 30-80 mesh by adding special equipment. This machine is widely used in the fields like mining, chemical industry, construction materials, metallurgy, etc. 
Working Principle:
In the mainframe of High Pressure Suspension Mill, there are strong springs with pressure as high as1000-1500 kg equipped on the roller suspender. When High Pressure Suspension Mill works, the roller rotates around the principal axis, and clings to ring under the effect of the strong spring and eccentricity. Its press is 1.2 times of Raymond mill under the same press condition, so the production is largely increased. When the materials are sent into the grinding chamber, they are brought to the space between the roller and ring and get grinded. Then the powder grinded will be blown into separator. The fine powder after departed with the air is discharged through the outlet as final product. The large-sized powder falls back for regrinding. The air will be back to the blower for repetition of the above process. The left air wil come to thel bag filter to get cleaned. When the wear and tear between roller and the ring reaches certain degree, adjust the length of the strong spring,, so to keep the invariable pressure between the roller and the ring, to make sure the stable production and the fineness.
Characteristics:
1. Compared with other mills, its capacity increases by 10%-20% under the same power condition, and compression force of rollers to material improve 800-1200kgf under the force of high-pressure spring.
2. Size of final product can be 0.613mm (30mesh) to 0.033mm (425mesh). Some can reach the fineness of 0.013mm (1000 mesh).
3. High Pressure Suspension Mill meets the requirement of national dust-dump standard.
4. The separator can be adjusted very easily.
5. The multi-class seals are adopted to keep the grinding equipment tightly closed.
The hammer crusher (hammer mill) crushes by the collisions between high-speed hammer and materiasl, and the hammer crusher (hammer mill) features in its simple structure, high reduction ration, high efficiency, etc. The PC hammer crusher (hammer mill) was developed for both dry and wet crushing of brittle, medium-hard materials for the mining, cement, coal, metallurgic, construction material, road building, and petroleum & chemical industries.

Operating principle of Hammer Crusher:
In the hammer mill machine, the motor drives the rotor rotate at a high speed through the belt, and on the rotor there are series hammers. When the materials get into the working area of hammers, the rotating hammers with high rotation speed are crushing them, the products which are crushed to meet the required size can be discharged by the outlet and become the final products, the large size products are brought back to the crushing area by the hammers for being recrushed until they reached the required size.

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, and use economically, etc. The spring safety system of crusher acts as an overloading protection system that allows metals 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 separated to make surereliable performance. The type of crushing chamber depends upon the size of feeding and fineness of the 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.

Working Principle of Cone Crusher:
Cone crusher crushes materials by the working surface between the movable cone and fixed cone. So it is more advanced and efficiency than jaw crusher. The movable cone is supported by spherical bearing and fixed on an hanging erect shaft which is set in the eccentric sleeve, and the sleeve is set on the stopping and pushing bearing. The movable cone and erect shaft are drived 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 drived 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 diacharge hole. The fixed cone can be ascended or descended by adjusting setting to adjust the width of discharge hole, consequantly the output size is determined.

Raymond grinder(Raymond mill) produced by our company is mainly used to grind non-inflammable and non-explosive materials with Mohs hardness below 7 and moisture content below 6% such as barite, calcite, potash feldspar, talcum, marble, limestone, ceramic, glass, etc Raymond grinder can be used in mining, chemical industry, construction materials, metallurgy and so on. The final products can be adjusted freely from 100 mesh to 425 mesh. 
Working Principle of Raymond Grinder(Raymond mill):
Firstly, raw material is crushed by jaw crusher to the size required, then elevated into a hopper from which the material is transported through the electro-magnetic vibrating feeder evenly and continuously into the grinding chamber for powder-processing. The rollers oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the materials, send to the middle between the ring and rollers to accomplish the grinding.After grinding, the rough materials will be recycled by the air from the fan back into the grinding chamber for regrinding and the fine powders are blew into the cyclone and poured out through the output-powder pipe as the final products.

The ball mill is a key equipment to grind the crushed materials, and the ball mill is widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc, and the ball mill can grind various ores and other materials with dry type and wet type. There are two kinds of ball mill, grate type and overfall type due to different ways of discharging material. 
Working Principle:
The ball mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The ground materials are discharged through the discharging board thus the grinding process is finished.
