The impact crusher can process materials with a side length of less than 100-500 mm, and its maximum compressive strength can reach up to 350 MPa. It has the advantages of large crushing ratio and cubic particle shape after crushing, making it suitable for crushing medium-hard materials. It features large production capacity, high crushing ratio, and fine output particle size. The impact crusher is widely used in the construction materials, chemical, and coal industries for coarse, medium, and fine crushing of medium hardness and brittle materials such as limestone, dolomite, shale, sandstone, coal, asbestos, graphite, and rock salt.
Main performance advantages of the impact crusher (counterattack breaker):
1. Large crushing ratio, generally ranging from 10-20, and can reach up to 50-60 in some cases;
2. Simplified crushing process, simple structure, easy manufacturing;
3. Convenient use and maintenance, and capable of selective crushing;
4. However, due to the concentrated wear of the blow bars, its application in crushing hard materials is limited.
Working principle of the impact crusher (counterattack breaker): During operation, the rotor rotates at high speed under the drive of the motor. After entering the machine, the material collides with the blow bars on the rotor for crushing, and then rebounds to the liner plate for secondary crushing. Finally, the crushed material is discharged from the outlet.
Note: This series of impact crushers is suitable for hard rock crushing. For example, the typical product, granite, has an output particle size of ≤40mm accounting for 90%.
