The root cause of the movable jaw of the jaw crusher is the three major hidden dangers of quality, operation and feeding. The solution lies in the selection of wear-resistant materials, standardization of installation procedures, and strengthening of operation training, so as to cut off the risk of overload operation from the root, and improve the life of the equipment and production efficiency.

The main reasons for the breakage of the movable jaw of the jaw crusher during the operation of the ore processing production line are as follows:

1. Quality problems

The service life of equipment or parts depends fundamentally on quality. Taking the movable jaw of the jaw crusher as an example, if the quality is poor, it is very easy to break under external force during use. The reasons for the poor quality of the movable jaw are mainly concentrated in two aspects: one is improper material selection, and the other is defects in the processing technology.

2. Operation problems

The jaw crusher has strict operation requirements. If the staff is not familiar with the operation process, it is easy to cause a malfunction due to improper operation. If there are unbalanced installation, loose bolts, and too fast spindle speed at the same time, the movable jaw will swing too fast. In the end, this abnormal state is very likely to cause the movable jaw to break in production.

3. Feeding problem

Feeding is an important link that affects the production of jaw crusher. The nature of feeding will affect the wear of jaw plate. When the nature of feeding exceeds the processing capacity of the equipment for a long time, it will cause the wear of jaw plate to increase, and the movable jaw will break.

How to solve the phenomenon of movable jaw breaking in jaw crusher

Based on the above analysis of the causes of movable jaw breaking, it can be seen that in order to solve the phenomenon of movable jaw breaking, attention should be paid to the following operations: first, the selection of movable jaw material and whether the processing technology is excellent, that is, to choose a movable jaw of good quality; second, during installation, the balance of equipment and the fixing of bolts should be ensured, and the staff should be trained before starting; third, the feeding should be strictly controlled.
