Impact crusher is also known as sand making machine, using the impact force to crush material, widely used in metal and non-metallic ores, cement, refractories, abrasives, glass raw materials, construction aggregate, artificial sand and a variety of metallurgical slag crushing and rough grinding operations. Particularly in the hard, especial hard and abrasive materials such as silicon carbide, corundum, sintered bauxite, magnesite ,it has more advantages than other types of crushing machine. For construction sand, gravel for roads it is especially appropriate .
Impact Crusher
Impact crusher structure features:
Impact crusher consists of a feed hopper, feeder, swirling crushing chamber, an impeller body, a main shaft assembly, a transmission device, and a motor ,totally seven parts. It has the advantages of simple structure, low cost, stable operation, high efficiency and energy saving. Due to materials’ dramatical lining in impeller and eddy broken cavity, the cost of wear parts and repair workload are reduced, effectively solves the "iron pollution" problem of the broken glass and other raw materials in the process of crushing and " steel blocked" issue n the process of breaking steel slag .The clever internal air circulation eliminates the dust dispersion.
Impact crusher performance characteristics:
1, the machine is novel, fine crushing equipment, currently widely used to replace cone crusher, roll machine, ball mill.
2, novel structure, unique, balance running.
3, small energy consumption, high yield, big crushing ratio.
4, small volume, convenient operation, convenient installation and repair.
5, with shaping function, a cube-shaped products, bulk density.
6, in the production process, the stone can form a protective bottom so as to no wear, durable of fuselage.
7, some consumable parts are made from hard and wear-resistant material.
Impact crusher operating principle:
Materials directly fall into the turntable of high-speed rotation from the upper of the machine , under the function of high-speed centrifugal force, which produce high speed impact and high density of the crushing with the other part (target stone) in umbrella type shunt on the turntabled. After impacting against each other, the materials will form the vortex motion between the turntable and the casing ,which causes more blowing, rubbing, crushing untill discharged through the lower part. It forms closed repeate cycles and achieves the required particle size controled by screening equipment.
