Jun 23, 2015 Impact Crusher Working Principle. Starting from the base working principle that compression is the forcing of two surfaces towards one another to crush the material caught between them. Impact crushing can be of two variations gravity and dynamic.
Impact Crusher is a broken machine which use of impact energy to crushing material. When the machine works, under the driving of the motor, the rotor high-speed rotation, the material into the plate hammer function area, and the impact of the rotor plate hammer crusher, and then be thrown to counterattack device broken again, then from the back lining board to board hammer region to break,
Impact crushers (e.g., hammer mills and impact mills) employ sharp blows applied at high speed to free-falling rocks where comminution is by impact rather than compression. The moving parts are beaters, which transfer some of their kinetic energy to the ore particles upon contact.
dynamic impact. When the material is crushed in an impact crusher, the freely falling material first breaks due to dynamic impact by a moving hammer and then the force of impact accelerates movement of the reduced particles toward breaker blocks and/or other hammers for further size reduction. Dynamic impact has specific advantages for the reduction of many materials and it is
