When the jaw crusher machine is working, the wear speed of the upper and lower parts of the crushing plate is different. The lower part wears faster than the upper part. When the crusher is working, the crushing plate is in direct contact with the material and bears the crushing force and friction of the material. , The service life of the crushing plate is directly related to the working efficiency and production cost of the jaw crusher. Therefore, it is particularly important to extend the service life of the crushing plate of the jaw crusher.
The jaw crusher machine is composed of a movable jaw and a fixed jaw. The crushing force it bears and the friction of the material are easily worn out. In order to protect the jaw plate, wear-resistant lining plates are generally installed on the surface of the movable and fixed jaws. The board is also called the broken board.

In production, the crushing plate acts directly on the material, and the crushing force is very large, especially when crushing materials with high hardness, it will cause the bolts of the crushing plate to vibrate and the nuts to loosen, which will aggravate the wear of the crushing plate and generate great noise. If the board falls off or breaks, the equipment shuts down and affects normal production.
The surface roughness of the liner. Appropriately reducing the surface roughness of the lining board is the way to improve the fatigue resistance. The required level of the surface roughness of the lining board is related to the contact stress on the surface of the lining board. Usually, the lining is required when the surface of the lining board is exposed to fire or when the surface hardness of the lining board is high. The surface roughness of the board is low.
