How Impact Crusher Works

Impact crushers use impact energy to crush materials. Driven by the motor, the rotor revolves at a high speed. Revolving blow bars in the rotor blow the materials. Then the materials will be thrown to the impact plates for secondary crushing. The materials will be shot back to the blow bars again . This process repeats until the materials are crushed to the required size and discharged through the discharging opening at the bottom of the machine. Adjustinng the gap between the impact rack and rotor support, the size and shape of the end products can be changed.

How Vertical Shaft Impact Crusher Works

Feed at center

Materials fall into the hopper and then through the feeding opening in the center enter the high speed rotor which will throw out the materials with high speed. Materials firstly strike those materials that are free falling down. Then, materials strike the materials-liner in the vortex or the impact liner and are rebounded to the top of crushing cavoty and then fall down. After that, the falling materials with materials shot from the impeller form a continuous materials curtain. Ultimately, crushed materials will be charged from the discharging opening.

Feed both in the center and from sides

The materials fall into the hopper and circle hole and then will be divided into two parts by the distributing plate. One part of materials cross the distributing plate and enter the high speed impeller and then is accelerated and thrown out .The other part falls down from the sides of distributor. Materials firstly strike the free falling down materials. Then, materials strike the materials-liner in the vortex or the impact liner and are rebounded to the top of crushing cavity and then fall down. The falling materials with materials shot from the impeller form a continuous curtain of materials. At last, crushed materials will be discharged from the discharging opening.
