1.Ensure that the jaws are installed correctly and securely. Make the jaw plate contact the surface of the machine smoothly. Otherwise, the jaw plate will be easily displaced during work, causing the jaw plate to collide with the inner wall of the machine and serious damage.

2.The thrust plate of jaw crusher is mostly cast iron, while the thrust plate seat is mostly cast steel or modified cast iron. It plays the role of transmitting motion and force, protecting safety and adjusting the size of ore discharge. Because the thrust plate is installed in the lower part of the body, it is not easy to maintain. Therefore, the plate head and the plate seat are the most prone to wear. The worn-out board head and board seat can be repaired by surfacing welding, spray coating, brush plating and other methods. When the thrust plate is broken, it is generally not repaired due to its function. The thrust plate should be replaced with a new one. However, the combined thrust plate can be removed for continued use.

3.We must do a good job of maintenance of the crushing equipment. Usually check the wear of the various parts of the crusher, and timely repair can extend the life of the equipment and save equipment investment.

4.The crusher vibrates a lot during operation. Fretting and abrasion during long-term work, the screw slide buckle, the screw hole is enlarged, and the through hole is worn, such as the foot bolt hole, the bearing screw hole, the spring rod support hole and so on. After these holes are worn, in addition to welding repairs, bolts can be replaced with welding pads or increased thread diameters.

5.Strictly control the feeding standards to prevent excessively granular materials from entering the machine. Other feeding materials should be uniform, otherwise the lower hopper inclination angle in the crushing chamber will be too large. The movable jaw indirectly collides with the material, causing severe damage to the jaw plate. It is strictly forbidden for the machine to cross the iron.

6.Improve the quality of the jaw. The raw materials of the jaw plate should be selected from materials with high hardness and good resistance. The higher the hardness, the less the surface deformation of the jaw plate. The better the jaw raw material resistance, the better the resistance to fracture.
