Hammer crusher ( hammer mill ) crushes by the collisions between high-speed hammer and materials,and the hammer crusher features are its simple structure,high reduction ratio,high efficiency,etc.The PC series hammer crusher were developed for both dry and wet crushing of brittle, materials for the mining,gold ore,copper ore,cement ,coal,metallurgic,construction material,road building and petroleum&chemical industries.The material discharge size can be adjusted by change the gap of the gridscreen,to meet the different needs of different users.Heavy hammer crusher can be directly used for material crushing without initial crushing.

 

Working Principles of hammer Crusher:

The electromotor drives the rotor to rotate with high speed in the crushing chamber. The materials are fed into the machine from the upper feeding mouth and are crushed under the hitting, impacting, cutting and grinding of the hammer which is moving with high speed. On the bottom of the rotor, there is sieve plate and the crushed materials that is smaller than the screen size are discharged from the sieve plate, and the coarse particles bigger than the screen size are retained on the sieve plate to be hit and ground again by the hammer and finally be discharged from the machine from the sieve plate.

 

1. It is big crushing ratio and the maximum feeding granularity can reach 1.3-1.5m.

2. The discharging granularity can be adjusted in the ranges of 3-150mm.

3.The discharging materials are fine has good shape, and the content of powder-shaped materials is below 20%.
