PFW impact crusher is mainly used to crush many kinds of large, medium, small materials whose side length is less than 500mm, and compression resistance should not be more than 350Mpa.PFW impact crusher are widely applied in many industries and working processes including highway construction, for building materials during construction, to break artificial rock, stone and sand, coal mines, chemical industry, hydroelectric industry, etc.

Working Principle of PFW Impact Crusher

This impact crusher crushes materials with impact force. When the materials enter the blow bar area, they are crushed due to the high-speed impact of the blow bar and are thrown to 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 discharged from the lower part of the machine. The size and shape of the finished powder 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.
