Measures to be taken when the jaw crusher is severely worn

Jaw crusher is a commonly used coarse crushing equipment in mining, building materials and other fields. Its main components are the movable jaw and the static jaw. The squeezing movement between the two achieves crushing of materials. When the jaw crusher is severely worn, the following measures can be taken for repair or maintenance:

1. Check and replace worn parts: Regularly check the wearing parts of the crusher, such as jaw plates, bearings, etc. Once serious wear is found, they should be replaced in time. When replacing, pay attention to selecting accessories that match the original equipment to ensure the normal operation of the crusher.

2. Adjust the discharge port: By adjusting the size of the discharge port, the crushing stroke of the material can be changed and wear can be reduced. Appropriately enlarging the discharge opening can reduce the number of extrusions of materials in the crushing cavity, thereby reducing the wear of the jaw plate.

3. Optimize the feeding method: distribute the feeding materials reasonably to avoid aniseed or debris from directly entering the crushing cavity and reduce the impact and wear on the jaw plate. You can consider installing pre-screening equipment to screen out unqualified materials in advance.

4. Improve the performance of wear-resistant materials: For parts prone to wear, high wear-resistant materials can be used or the jaw plate can be surface treated, such as surfacing wear-resistant materials, to improve its wear resistance.

5. Regular lubrication: Ensure that each lubrication point of the crusher is fully lubricated to reduce wear. Use appropriate lubricating oil and replace it regularly to maintain good lubrication of the equipment.

6. Strengthen daily maintenance: Develop and implement a strict equipment maintenance plan, and regularly inspect, clean, tighten and lubricate the crusher to ensure that the equipment is operating at its best.

7. Operating specifications: Train operators to operate in strict accordance with the operating procedures to avoid increased equipment wear caused by improper operation.

8. Monitoring and recording: Use status monitoring and fault diagnosis technology to monitor the operating status of the crusher in real time, record key parameters, and detect and handle abnormalities in a timely manner.

Through the above measures, the wear of the jaw crusher can be effectively reduced, the service life of the equipment can be extended, and the production efficiency and economic benefits can be improved. At the same time, these measures also meet the requirements of energy conservation, emission reduction and sustainable development, and are conducive to promoting the greening and sustainable development of industrial production.
