Hammer crusher has various types and can be classified into single rotor hammer crusher and double rotor hammer crusher according to the number of rotors. It also can be classified into reversible hammer crusher and irreversible hammer crusher in accordance with the direction of the rotation rotor.
The hammer crusher is developed for dry and wet type crushing of brittle and medium-hard materials for the mining, cement, coal, metallurgic material, construction material, road building, and petroleum and chemical industries. The hammer crusher crushes by the collision between high-speed hammer and materials.
Features of hammer impact crusher:
1. High crushing ratio; the crushing ratio ranges from 10 to 25 or even higher to 50.
2. Strong production ability;
3. Even particle size;
4. Low energy consumption;
5. Simple structure;
6. Light weight;
7. Easy operation and repair.
Working principle of hammer impact crusher:
In the hammer crusher machine, the motor drives the rotor to rotate at a high speed through the belt, and on the rotor there are a series of hammers. When the materials get into the working area of hammers, the rotating hammers with high rotation speed will crush them, and the products which are crushed to meet the required size can be discharged by the outlet and become the final products, then the large size products are brought back to the crushing area by the hammers for being re-crushed until they reach the required size.
