How to prevent main shaft of jaw crusher from breaking?

Fodamon engineers continue to explain the preventive measures to prevent and reduce the fracture probability of the jaw crusher main shaft as follows:

  1. For the operators of scraper, ground loader and transporter, it is necessary to improve their awareness of equipment maintenance and repair, ensure the integrity of bucket, gear, transportation belt and hinge pin shaft, and ensure that they will not produce metal impurities and enter the crusher. At the same time, timely repair and replace some gear and its surrounding parts with large wear.
  2. The operator needs to lubricate the special equipment according to the requirements. During the operation, it is necessary to check whether the lubrication of the equipment is good under safe premises, and always observe the operating load of the equipment. Observe whether the equipment has oil pressure, oil temperature and abnormal noise during operation.
  3. The supervisor shall be vigilant, pay close attention to the operation of the equipment, and timely clean up the foreign matters found in the machine to ensure that the equipment is in good operation condition.
  4. During the maintenance of the crusher, the waste parts damaged by the equipment should be reasonably recycled, and it is strictly forbidden to discard all kinds of metal substances into the ore at will. At the same time, some equipment near the end of scrapping and scrapping needs to be replaced directly.
  5. In daily work, it is necessary to pay attention to the amount of feed at all times to avoid the phenomenon of excessive feed, which may lead to the possibility of spindle breakage.
  6. Regularly use ultrasonic and other instruments to test the stress of the main shaft, understand the stress degree of the main shaft, and timely repair and replace the worn parts.
  7. Users can update or modify the existing metal detector to improve its ability of detecting and removing metal.
  8. For the main shaft, the body of the crusher, and other more important equipment parts, inventory backup should be done to avoid stopping the entire production system after a special situation, thereby affecting the overall smoothness of production.
  9. Strengthen the professional skill training of operators in all links, improve the actual operation ability of operators as much as possible, improve the maintenance effect of the equipment, timely overhaul and medium repair the equipment, and ensure that the equipment is in good working condition for a long time.
