Jaw crusher is composed of movable jaw plate and fixed jaw plate. The movable jaw and fixed jaw need to bear large impact force and friction of raw materials. The jaw part is easily damaged. In order to protect the jaws, we have installed wear-resistant linings on the surfaces of the fixed and movable jaws. This liner is called a jaw plate. When the crusher is working, the jaw plate is in direct contact with the raw material, and the jaw plate damages the jaw plate. The service life of the jaw parts of the jaw crusher directly affects its work efficiency and productivity, so the service life of the jaw parts of the jaw crusher is very important. How to prolong the service life of the jaw parts of the jaw crusher?

　　1. It can be improved from the aspects of material selection, design, assembly and use. In the design, the jaw plate can have peaks and valleys. In this way, in addition to extruding the raw materials, it can also play a bending role, and the raw materials are easily broken.

　　2. In order to prolong the service life of the jaw plate, the jaw plate is designed in a symmetrical shape. If the lower part is damaged, it can be turned over.

　　3. During installation, the jaw plate should be firmly fixed on the jaw plate, and the two jaw plates should be cushioned with soft metal, and then fastened with bolts. When the crusher is installed, the jaw plate should be installed well, which can prolong the service life of the jaw plate.
