What are the causes of wall wear?

Crushing wall is the internal parts of the crusher, can have the effect of blocking, we were to objects in a broken, these items material is compared commonly hard, so use the broken wall must choose firm can be broken, although the crushing wall material is very hard, but due to gravity, and the role of high speed rotating Items in the process of crushing will also make the broken wall wear quickly, what are the specific causes of the broken wall wear?

Hardness and particle size of ore

The higher the hardness of the material, the greater the impact load of the lining plate in production. When the hardness of ore is the same, the larger the particle size of ore entering the crushing chamber, the more serious the wear of lining plate.

Improper feeding method

If the feeding device of cone crusher is improperly installed, or too much material is put into the crushing chamber, it will lead to uneven feeding, material blockage and other faults in the crushing chamber, so that the unilateral force of the lining plate is too large, and the cutting wear of the ore on the lining plate is increased, and the lining plate is seriously damaged.

The lining plate is stressed greatly

The extruded ore exerts huge pressure on the local surface of the lining plate, while the high-speed operation of the moving cone produces huge shear stress. Both of them act simultaneously, and the main wear mode of the lining plate is chiseling, cutting and impact extrusion pit.

Bad operating conditions

Cone crusher is used in mineral processing production. According to the different types of ore body rock, the wear degree of lining plate of cone crusher is related to the stress and size of ore, as well as the Prinell hardness of ore compressive strength.

Crushing wall can help us at the time of product broken, reduce material splash and losses caused by the crushing process, at the same time of saving material, also can better to protect our security, so we need to know the broken wall causes of the wear and tear, and then find a solution, can be better for the use of the broken wall, Work efficiency can also be improved.
