1.  Adopting new technology, the working hammer is designed has features of reliable wear-resistance and impact resistance.

2.  The distance between gird sections, discharge size all can be altered at user's will.

3.  The sealed structure has solved the problem of dust pollution and ash leakage in the crushing plant.

4.  Scientifically rational sructure design ensures reliable running, low consumption of wearing parts and operation cost.

The electromotor drives the rotor to rotate at high speed, when the materials are fed into the crushing chamber, they are crushed by impacting, cutting, hitting and grinding from the hammer which is moving with high speed. On the bottom of the rotor, there is sieve plate, the crushed materials with smaller size than the screen size are discharged from the sieve plate, and the coarse particles bigger than the screen size are retain on the sieve plate for further hitting and grinding by the hammer until they are crushed to the required granularity, and then discharged from the sieve plate
