- The stone material is rolled into the inner side of the wheel, causing the flywheel wheel housing to crack;
- Casting defects;
- The flywheel wheel tension sleeve is loose.

Fault phenomenon 2: The frame is crazing.
The reason:
- Casting defects or welding quality defects;
- Use of unqualified brackets and brackets, when the crusher is under strong impact, the brackets are not self-breaking, causing the frame to crack;
- The fixed jaws are not fixed Long-term ups and downs, hitting the front frame of the rack;
- The rigidity of the base of the base is poor or collapsed, the frame is beating;
- The two bolts on the bearing cover are loose;
- Fixed the movable jaws continue to be used after the tooth shape is worn;
- The direction of the weight of the flywheel wheel is misaligned due to the eccentric shaft, the pin damage or the loosening of the sleeve.
Method of exclusion:
- Remove the original crack defects, repair the repair, and replace the new frame if necessary;
- Repair or replace the new frame, and replace the original bracket and bracket pad produced by the main machine factory;
- Repair or replace the new machine Rack and fix the fixed stud bolts;
- Repair or replace the new frame, and tighten the frame foot bolts to correct the level and strengthen the foundation;
- Repair or replace the new frame and tighten the bearing cap Upper two bolts;
- Repair or replace the new frame, and replace the jaws in time;
- Repair or replace the new frame, and change the pin shaft or adjust the direction of the eccentric block to tighten the expansion sleeve.
