crusher working principle 

When the  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. 

Rock Impact crusher is used in crushing all kinds of materials whose fineness is below 500mm,and the pressure resistance around 360mpa. It has the features of big crushing rate, efficient crushing, easy maintenance and cubic shape with final product. It is an ideal mining equipment for high road and water conservancy.

Features of impact fine crusher

1).Large feed size and high crushing chamber are suitable to crush hard and big materials.

2).Space between impact plates and hammers can be adjusted conveniently,so the shape and size of final product can be controlled.

3).New type of abrasion-proof materials are used, so life of hammers, impact plates and lining plates is much longer.
