Principle of operation:    

The rotor pan propelled by the motor, takes the hammerhead to do high-speed rotatory movement. After the materials entering the crushing cavity, big pieces of the materials are piled on the fixed middle bearing rod of the crusher;after being broken,the grain size which is bigger than the demanded material will be hit into the repercussion plate among the hammer head tangential direction,and then to be broken again, so as to make sure of the coarse, medium, fine in one-step process.Finally, the material up to the need will be dismounted through the comb board.
