When the jaw crusher is working, the crushing plate act on material directly, the crushing force is large, especially crushing the harder materials, which led to the bolts of crushing plate vibrating, broken plates increasing wear and tear, producing noise, affecting the normal production. In this case, just before starting, tightening bolts and nuts cannot completely solve the problem, should according to the site actual situation of to find ways to take a practical approach to solve the problem. For example, you can work to solve the crushing plate loose spring locking damping device, thus extending the life of the broken board, and improve work efficiency.
The specific approach is to use a spring that made of a bolt anti-loosening and self-tightening device, the apparatus is composed of inner spring, springs, outer spring capping. This device is to tighten the nut on the bolt, since the spring is pressed onto the nut to a certain extent after strong damping effect, the bolt loose power generated by huge crushing force, so as to avoid the bolts loose, thus extending the life of the broken board, improve production efficiency.
In short, in the course of the specific situation to find ways to solve specific problems, to prevent the crushing plate loose, increased wear, broken, etc., thus extending the life of the broken board, reduce costs and improve efficiency.
