When the jaw crusher is working, the movable jaw plate periodically reciprocates against the fixed jaw plate. When approaching, the materials are crushed by squeezing, splitting, and impact between the two jaws; when leaving, the crushed materials are discharged from the discharge port by gravity. Therefore, the jaw plate is one of the easily worn parts of the jaw crusher.
How can we reduce the wear of the jaw plate of the jaw crusher? 　　 1. Choose a material with strong abrasion resistance. When buying a jaw crusher or replacing the jaw plate, be sure to choose a jaw plate made of materials with high hardness, strong toughness and good wear resistance.
　　2. Pay attention to the tightness of the jaw plate when installing. A firm fixation during installation is basic. The jaw can be a toothed jaw. If necessary, a layer of plastic material can be placed between the jaw and the jaw to make the jaw firmly fixed on the jaw. Make the contact between the jaws of the jaw crusher smooth and reduce friction.
　　3. Control the feed size. Generally speaking, the feed size of the jaw crusher should be controlled within 85 percent of the larger size of the feed inlet, so as to avoid damage or excessive wear of the jaw plate caused by oversized stones, and to ensure the crushing effect and efficiency.
　　 4. Sampling inspection of materials. Since the composition, hardness, humidity, mud content and other factors of the material have a er impact on the of the jaw plate, before the material enters the crushing cavity, check whether there is any foreign matter or material with high hardness in the material, and remove it if any Foreign matter or adjust the parameters of the crusher for materials with high hardness to make them match the crushed materials.
