Why is the crusher easy to wear the stripper plate?

Answer:

The surface of the liner is in a complex state of stress, and the extruded ore causes great pressure on the local surface of the lining plate, producing a chisel, cutting and impact on the lining plate, and the main form of wear is the extrusion pit.

When the hardness of the ore is the same, the larger the size of the ore into the crushing cavity, the more serious the wear of the liner. If the crusher feeding device is installed improperly, or into the crushing chamber materials too much, will lead to uneven feeding, crushing cavity material blockage fault, the liner unilateral excessive force, increase of ore cutting wear liner, the liner badly damaged.

Counterattack crusher is used in ore dressing production. According to the rock type of ore body, the wear degree of crusher liner is related to the force condition and size of ore, and it is also related to the hardness of ore compressive strength. The hardness of the crushed material is different, and the degree of wear of the liner is different. The higher the hardness of the material to be broken, the greater the impact load the liner will bear during production;
