1. Change the parameters in time. Each batch of materials entering the jaw crusher be sampled. Once the properties of the materials change significantly, the parameters of the jaw crusher be changed in time.
2. Improve the wear resistance of the jaw plate. The jaw plate of the jaw crusher be made of materials with high hardness, wear resistance and strong impact resistance. Enterprises with mine crushing production line technology can interchange the worn jaw plates of mine crushing and cement fine crushing. 3. Repair wear and tear in time. In the normal production of the jaw crusher, pay attention to checking the usage of the jaw plate. The worn jaw plate can be repaired by surfacing welding to extend the service life of the jaw plate.
4. Install the jaw firmly. The newly installed jaw plate be tightly fixed and installed, and it is in smooth contact with the surface of the jaw crusher, and a layer of material with better plasticity can be placed between the jaw plate and the surface of the machine.
