Repair and Maintenance of Jaw Crusher

Jaw crusher is mainly composed of frame, eccentric shaft, belt pulley, flywheel, fixed jaw plate, movable jaw plate, toggle plate and return spring. The working environment of jaw crusher is harsh, and various failures often occur during operation. In order to ensure the stable operation of the equipment and improve the performance of the equipment, it is very important to do a good job in daily maintenance.

1. Frequently check the tightness of all fixed parts, the elasticity of the spring and the tension of the transmission belt, and check all the connected parts frequently.

2. It is necessary to check whether there is oil in the bearing part frequently. To ensure that the machine works for a long time, it is necessary to frequently add grease to the contact between the toggle plate in the bearing and the sliding block, lifting, wedges, and toggle back seat.

3. Minor repair: According to the overall operation of the machine, check and repair the corresponding adjustment device, adjust the clearance of the discharge port, and then replace the worn liner; clean the individual parts of the crusher ; The thrust plate should also be repaired and replaced with corresponding transmission components.

4. Intermediate repair: Intermediate repair not only includes all items of minor repairs, but also replaces the worn structures such as tie rods, liners, bushings, thrust plates, etc., and the interval of intermediate repairs should also be based on the overall wear and use of the machine to make sure. The tie rod will appear cracks, breakages, deviation of the bearing hole, wear or deflection of the groove of the support pad during the work process. When the tie rod fails and the machine cannot run, take appropriate repair measures or replace it to restore it To normal working condition.

5. The main content of the overhaul includes all the items in the middle repair, the replacement of the eccentric shaft and bearings of the crusher, and the replacement of all worn parts and component structures. There is no specific time limit for the overhaul, which is based on the usual inspection level.

Maintenance management plays a very important role in the overall operation of the jaw crusher. Do a good job in daily maintenance, and perform corresponding treatments according to the specific conditions to achieve the optimal performance of the equipment.
