Hammer crusher (hammer mill) is applicable for various hard and fragile materials, such as limestone, coal, salt, gypsum, alum, brick and tile, etc. The crushing compressive strength of materials should not be in excess of 150 Mpa. Hammer crusher is mainly used in industries such as cement, coal separation, electricity generation, building materials and compound fertilizer, etc. And hammer crusher can crush materials with different sizes into equal particle, which favors the next procedure.
1. Big reduction ratio: maximum feeding size is 1.3-1.5m; 3-150mm of discharging size.
2. High fineness of discharging size: favorable shape with aggregate, the powdery material is no more than 20%.
3. Simple process: the two or three stage crushing is reduced into single stage.
4. Economical: small capacity of matched motor, which greatly reduces the production cost.
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 reach the required size.
