mpact crusher is the world advanced equipment with high energy and low consumption developed by Mr. Bai Yinghui, an expert in our company, based on researching mine machinery and incorporating advanced technology of similar products in Barmag Company. Its performance plays an unsubstitute role in various ore fine breaking equipment. 

Uses: This machine is used widely in ores, cement, refractory, bauxite, corundum, glass, machine-made building sand, stones and various metallurgical discards. Especially in the grinding of extra hardness, special hardness and anti-resistance materials as silicon-carbide, corundum sintered bauxite and magnesia, it has a high efficiency compared with other types of grinder. 工Operating principle：Materials drop from the top of the machine into the impeller with high speed. With the function of high speed centrifugal force, they are impacted and broken with high speed with other materials spread in umbrella-type around the impeller. After impacting each other, the materials will become whirling between the impeller and the shell. Then they impact and abrade each other again followed by breaking. Broken materials are discharged from the bottom. Thus, multi closed cycles are formed. Finished products granularity required is controlled by screening equipment。
Operating features：(1) Simple and reasonable structure and low operation cost. (2) High breaking rate and energy saving. (3) Function of fine breaking and rough abrading. (4) Water content of the materials has a little influence and the water content can reach 8%. (5) It is more suitable for breaking materials with middle special hardness. (6) Finished products are cubic with large density of stacking. The pollution of iron is very small.（7）The wear of impeller cleading is very small and the maintenance is very convenient. （8）Operating noise is below 75db（db grade）and the pollution of powder is very small.
