In the production process, the crushing tooth plate directly interacts with the material, and the crushing force is very large. Especially when crushing the material with high hardness, the vibration of the bolt for installing the crushing tooth plate is easily caused, the nut is loosened, and the crushing tooth plate is abraded and intensified. Large noise, severely broken or broken tooth plate breaks down the equipment, affecting 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 vibration-reducing device can be used to solve the loosening of the crushing tooth plate during operation, thereby prolonging the service life of the crushing tooth plate and improving work efficiency. The specific method is to use springs to make bolts to prevent loosening and self-tightening devices. The device consists 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 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 cannot be loosened, thereby prolonging the service life of the crushing tooth plate and increasing the production efficiency. In short, in the process of use, we can solve specific problems according to specific conditions to prevent loosening of the tooth plate, increased wear and tear, breakage, etc., thereby prolonging the service life of the crushing tooth plate, reducing costs, and improving work efficiency.
Strengthen the service life of jaw crusher jaws from the aspects of design selection, assembly, and improvement in the use process. It can strengthen the service life of crushing tooth plates, thereby improving the production efficiency of jaw crusher and reducing Cost of production.
