The hammer crusher (hammer mill) crushes by the collisions between high-speed hammer and materials,and the hammer crusher (hammer mill) features are in its simple structure, high reduction ration, high efficiency, etc. The PC hammer crusher (hammer mill) were developed for both dry and wet crushing of brittle, medium-hard materials for the mining, cement, coal, metallurgic, construction material, road building, and petroleum & chemical industries.

Operating principle of Hammer crusher :

The motor drives the rotor rotate of the hammer crusher  at a high speed through the belt, and on the rotor there are series hammers. When the materials get into the working area of hammers, they are crushed by the rotating hammers of the hammer crusher  with high rotation speed, the products which are crushed to meet the required size can be discharged by the outlet and become the final products, the large size products are brought back to the crushed area by the hammers of the hammer crusher  for being recrushed until they reached the required size.
