Description

Application Great Wall impact crusher can be applied to primary, secondary and fine crush, it is widely used to process all kinds of hard materials(like granite, marble, limestone, basalt, etc.) with comprehensive strenth less than **0 Mpa in the industries of roads, mineral, railways, water conservancy project, electricity power, chemical industry, building materials, etc. Working Principle This impact crusher brokes materials via impact force produced in the crusher. When the materials enter the blow bar area, with the the high-speed impact of the blow bar, they are flung into the impact plates on the rotor for secondary crush. Then the materials will be shot back to the blow bar again for the third crush. This process repeats until the materials are crushed to the required size and then are discharged from the outlet of the impact crusher. The size and shape of the end product can be changed by adjusting the gap between the impact rack and rotor support. The machine employs self-weigh security device in its back frame. When other objects enter the impact cavity, they will be forced out of the machine by the impact rack in the front and back of the machine.
