The operation of the jaw crusher is the extrusion and crushing of the movable jaw and the fixed jaw. During the crushing process, the amount of wear of the jaw plate is relatively large, especially when encountering hard materials, the degree of crushing will become more serious. How to reduce the wear of the jaw plate and improve the utilization rate of the crusher?     1. The choice of plate is the factor that determines the service life
    The jaw plate should choose a material with high hardness to resist the damage of extrusion micro-cutting, and choose a material with sufficient toughness to resist the fatigue damage caused by drilling impact. High manganese steel contains 12% manganese and 14% manganese and is usually used to form the jaws. Small jaw crushers can also make jaws from white cast iron. At the same time, the structure of the toothed plate can be improved, and the relative sliding between the material and the toothed plate can be reduced. Since the lower jaw plate is usually made in a symmetrical shape up and down, the lower worn lower jaw plate can be inverted during minor repairs.
    2. The crushed materials should be adapted to the whole machine
    When the of each batch of materials fluctuates , the main parameters of the crusher, such as clamping angle, eccentric shaft speed, output power, motor power, etc., are adjusted in time to meet the material requirements of the feed crusher and reduce the jaw Board wear.
