How to prevent main shaft of jaw crusher from breaking?

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

For scraper, ground loader, and transporter operators, it is necessary to improve their awareness of equipment maintenance and repair, ensure the integrity of the bucket, gear, transportation belt, and hinge pin shaft, and ensure that no metal impurities enter the crusher. At the same time, they should repair and replace some gear and its surrounding parts with significant wear promptly.

Operators need to lubricate the special equipment according to the requirements. During the operation, it is essential to check whether the equipment’s lubrication is good under safe conditions, observe the operating load of the equipment, and whether it has oil pressure, oil temperature, and abnormal noise during operation.

Supervisors should be vigilant, pay close attention to the equipment’s operation, and promptly clean up any foreign matter found in the machine to ensure that the equipment is in good operating condition.

During the crusher’s maintenance, the waste parts damaged by the equipment should be reasonably recycled, and it is strictly forbidden to discard any metal substances into the ore randomly. Also, some equipment near the end of scrapping and scrapping needs to be replaced directly.

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.

Regularly use ultrasonic and other instruments to test the main shaft’s stress, understand the stress degree of the main shaft, and promptly repair and replace worn parts.

Users can update or modify the existing metal detector to improve its ability to detect and remove metal.

For the main shaft, the body of the crusher, and other important equipment parts, inventory backup should be done to avoid stopping the entire production system after a particular situation, thereby affecting the overall smoothness of production.

Strengthen the professional skill training of operators in all links, improve the operators’ actual operation ability as much as possible, improve the equipment’s maintenance effect, and timely overhaul and medium repair the equipment to ensure that the equipment is in good working condition for a long time.

In addition to these measures, it is also important to choose a high-quality jaw crusher that is designed to withstand the demands of heavy-duty crushing. A well-designed jaw crusher will have a strong and durable main shaft that is built to withstand the stresses of crushing operations.

By taking these steps, it is possible to prevent the main shaft of a jaw crusher from breaking, which can help to minimize downtime, reduce repair costs, and ensure that the crushing process runs smoothly and efficiently.
