What causes the jaw plate to wear?
1. If there are impurities in the jaw plate of the jaw crusher, it will cause stress concentration. Cracks are easily formed on the edges of impurities, reducing the contact fatigue life of the material. Structural status, internal defects and other factors also have a great impact on the wear of the jaw plate.
2. The tooth tips of the movable jaw plate and fixed jaw plate of the jaw crusher should face the tooth alveolus. During the working process, the raw materials are mostly in irregular shapes and are crushed by the extrusion force through point contact. In addition, the gravity of the raw material brings continuous friction to the movable jaw plate and the fixed jaw plate, generating friction and shear stress. The motorized shaft of the jaw crusher moves forward driven by the movable jaw plate. In this process, the raw materials are crushed.
3. The jaw plate fastening bolts of the jaw crusher play a role in protecting the jaw plate during operation. During the working process of the jaw crusher, the force between the raw material and the jaw plate is very large. Especially when working continuously or crushing raw materials with high hardness and large size, the screw is easy to loosen due to vibration force. In this case, the jaws may slip, fall off, break, or become damaged.
4. During the operation of the jaw crusher, especially when the crushing ratio is large, the material is blocked more seriously, making it difficult or even impossible to crush the material. In this case, under the action of the extrusion force of the jaw plate, the instantaneous sliding amount of the raw material becomes larger. After sealing, many customers use blasting method, which is very convenient and fast. However, this method will cause changes in the texture of the jaw plate and accelerate the wear of the jaw plate.
