Analysis on the Causes of Wear of the Fragile Parts of the Jaw Crusher

Jaw crusher, comm known as jaw crusher, also known as tiger mouth, is an earlier crushing equipment. Because of its simple structure, sturdiness, reliable work, easy maintenance and repair, and relatively low production and construction costs, it is still widely used in mining, smelting, building materials, highways, railways, water conservancy and chemical industries and many other sectors. The compressive strength has not been stained with various materials of 320 MPa. Due to the poor working nature of the jaw crusher, its components are susceptible to wear during production. Let's take a look at the reasons for the wear of the vulnerable parts of the jaw crusher.

    1. Wear of the movable jaw: The movable jaw of the jaw crusher is the main part of crushing materials, so the abrasion of the movable jaw is mainly due to the friction of the material, especially when the material in the crushing cavity is blocked, the material squeezes the movable jaw many times , Resulting in fatigue wear and even failure of the movable jaw. On the other hand, if the movable jaw is displaced during production, the movable jaw will collide with the protective plate of the inner wall of the fuselage, accelerating the wear of the movable jaw.
    2. The wear of the tooth plate: the tooth plate is the same as the jaw plate of the jaw crusher, and the service life is shorter. It can be seen from the failure of the tooth plate in the past that there are many wear marks and micro cracks on the tooth plate caused by the short-distance sliding of the sharp corner of the abrasive. Therefore, the wear of the tooth plate of the jaw crusher belongs to the chisel abrasive wear. That is to say, the improper particle size and hardness of the materials in the equipment will cause serious wear of the tooth plate. On the other hand, if the impact speed of the material entering the equipment is too large, the tooth plate will also be severely worn.
