Hammer mill machine crushes by the collisions between high-speed hammer and material, and the hammer crusher (hammer mill machine) has the features of simple structure, high reduction ratio, high efficiency, etc.
 
 
The PC hammer mill machine is developed for both dry and wet crushing of brittle, medium-hard materials for the mining, cement, coal, metallurgic material, construction material, road building, and petroleum & chemical industries.
 
Working principle of Hammer mill machine:
In the hammer mill  machine, the motor drives the rotor to rotate at a high speed through the belt, and on the rotor there are series of hammers. When the materials get into the working area of hammers, the rotating hammers with high rotation speed are crushing them, the crushed products meeting the required size can be discharged by the outlet and become the final products, the large size products are brought back to the crushing area by the hammers for being re-crushed until they reached the required size.
