Hammer crusher is commonly used secondary crushing equipment, can break the largest particle size of 600-1800 mm of material to below 25 or 25 mm. It is suitable for crushing medium hardness materials such as limestone, slag, coke, coal and other materials in cement industry, chemical industry, electric power industry, metallurgy industry and other industrial sectors. The equipment used in the field of mining crushing, is one of the very popular crushing equipment.

Working principle of hammer crusher

Hammer crusher is breaking the material in the use of impact energy, and the hammer is the most important part of the working part. When the equipment works, the motor drives the rotor for high-speed rotation, and the material is poured into the crusher chamber through the feeding device evenly, then the high-speed rotary hammer impacts, shears and tears the material, resulting in the material is broken. At the same time, because of the gravity of the material itself, the material rushes to the frame body baffle, screen bar from the high-speed rotation of the hammer, and rushes to the baffle will be crushed again. On the contrary, rushed to the screen of the material, less than the size of the screen will discharge out of hammer crusher, inversely the material retains in the sieve plate which more than the size of the screen to continue to be hit and grinded, until the crushing to the desired size of the final material through the sieve the plate is discharged out of hammer crusher.
