3 ways to crush materials with impact crusher

[liu yoyo]

The Small Scale Stone Crushers Machines In Kenya adopts the impact principle to achieve selective crushing of materials during work. Its product has good grain shape and few pin pieces. It is often used for the final crushing of subgrade roads with high aggregate requirements. It can also be used for building materials, Mining and metallurgical industry in fine crushing operations. During work, the impact crusher crushes the material in the following processes:

1. Free crushing in the crushing cavity

The ore entering the crushing cavity will soon receive the impact of the plate hammer on the rotating rotor at high speed, and it will also be affected by the collision between the materials. These forces cause the material in the crushing cavity to be crushed.

2, rebound and break

The crushed materials are not actually dispersed indefinitely, but they are all sorted in a box-shaped frame. Due to the action of the striking hammer on the high-speed rotating rotor, the material obtains a high speed of movement, and then hits the frame. The frame acts on the material with a force of the same size and in the opposite direction, so that the material is further broken. The crushing effect is also called 'rebound crushing'.

3. Shear breaking

Shear crushing is the material that is not crushed by the free crushing and rebound crushing that is larger than the size of the discharge port, and is broken by the high-speed rotating hammer at the discharge port.
