What is the reason for the cracking of crusher frame?
Time of publication:2022-06-20
1. The movable jaw and fixed jaw of the crusher continued to be used after the tooth profile was worn, and they were not repaired in time.

2. During the production of crusher, the casting technology or welding is not in place, resulting in the quality problems of the equipment itself.

3. The fixed jaw plate was not fixed firmly enough, and the crusher was in a continuous vibration state for a long time, which caused the fixed jaw to loosen and hit the toothed plate on the front wall of the rack, causing damage to the rack.

4. The bolts of the rack bearing were not tightened during installation, resulting in looseness.

5. The rigidity difference of the foundation of the equipment host is out of tolerance or collapses, causing the frame to jump;

6. The eccentric shaft and pin are damaged or the expansion sleeve is loose, resulting in the misalignment of the counterweight of the flying sheave.


7. The material of elbow plate and elbow pad is unqualified, which can not bear the huge impact force. When the crusher is under strong impact, it can not play the role of buffer and self-protection, resulting in frame damage or fracture.
