Method to Enhance the Durability of Jaw Crusher’s Crushing Plate

During working process, the crushing plate directly contacts with the materials that receiving large crushing force and material friction. It service life has close relationship with the working efficiency of jaw crusher and production costs. This text discusses the method to enhance the durability of crushing plate from design, material selection, assembly, technology improvement during operation and other aspects.

1. Structure and material selection. In order to prolong its service life, the upper and bottom crushing plate of small and medium size crushing machine are designed symmetrically, if the bottom plate is worn, can turn around for further use.

2. Assembly. When assemble the jaw crusher, the crushing plate must contact closely to the jaw plate. The crushing plate should not loose during operation, otherwise it is easy to break or wear crushing plate, and reduce its durability.

3. Using process. Normally we can prolong the service life of crushing plate through tightening the bolts and nuts of jaw crusher, but this cannot completely solve the problem. We should find a way to take practical and feasible method according to the actual situation to solve the problem.
