The crush plate is worn out and generates a great amount of noise. In severe cases, the crush plate breaks off or breaks to stop the equipment and affect normal production. In such cases, only tightening the bolts and nuts before starting up can not completely solve the problem. It is necessary to analyze specific problems according to the actual situation on the spot and think of ways to take practical and feasible solutions to the problems. For example, a loose-proof spring-damping device can be used to solve the loosening of the crush plate during operation, thereby prolonging the service life of the crush plate and improving work efficiency. The specific method is to use springs to make bolts to prevent loosening and self-tightening devices. The device is composed of inner spring glands, springs, and outer spring glands. Put this device on the bolts to tighten the nuts, because the springs are pressed to a certain extent by the nuts. After that, it produces a strong anti-vibration effect. The bolt loosening force generated by the huge crushing force is automatically compensated by the spring tensioning force, so the bolt will not be loosened, thus prolonging the service life of the crushing plate and increasing the production efficiency. In short, in the course of use, we can solve specific problems according to specific conditions to prevent loosening of the crush plate, increased wear and tear, breakage, etc., thereby prolonging the service life of crush plates, reducing costs, and improving work efficiency.
Jaw crusher preparation before starting:
1, should carefully check the bearing lubrication is good, whether there is enough grease in the bearing bracket connection.
2. Carefully check that all fasteners are fully tightened.
3. Whether the protective device is good or not, and the phenomenon of insecurity is found, it should be eliminated immediately.
4. Check if there are any ore or other debris in the crushing chamber, and if any, remove it immediately.
