Main purpose of hammer crusher

The ring hammer crusher is used to crush a variety of medium hard and abrasive materials. The compressive strength of the material does not exceed 100 MPa, and the water content is less than 15%. The crushed materials are coal, salt, chalk, gypsum, brick, limestone and the like. The main working component of the ring hammer crusher is a rotor with a hammer (also known as a hammer). It is crushed by the impact, impact, shearing and grinding action of a high-speed hammer. In the lower part of the rotor, a sieve plate is arranged, and the size of the pulverized material smaller than the mesh size is discharged through the sieve plate, and the coarse-grained grade larger than the mesh size is retained on the sieve plate and continues to be struck and ground by the hammer, and finally passed through the sieve plate. Discharge outside the machine.

The hammer crusher mainly relies on the impact to break the material. The crushing process is roughly like this. The material enters the crusher and is broken by the impact of the high-speed rotary hammer. The broken material gets the kinetic energy from the hammer. From the high-speed rushing to the baffle and the screen strip in the frame, at the same time the materials collide with each other and are crushed several times. The material smaller than the gap of the screen strip is discharged from the gap, and the larger material is again on the screen strip. The hammer is impacted, ground, crushed and crushed, and the material is extruded from the gap by the hammer to obtain a product of the desired particle size.
