Jaw Crusher Maintenance Methods and Repairs
The jaw crusher, also known as the jaw break, is an essential type of crushing equipment. To ensure it performs optimally and to extend its service life, proper maintenance is crucial. The following recommendations are provided for users’ reference:

1. Regular Inspection of the Jaw Crusher
Users should perform daily inspections of the jaw crusher, especially when the equipment is newly installed. Before starting the machine, operators must carry out a comprehensive inspection, including checking the electrical wiring, motor, fastening components, belt transmission, and bearing seals. In addition, it is important to regularly check the wear condition of key parts such as the jaw plate, impact liner, and other liners. Severely worn parts should be replaced in a timely manner to ensure continuous and efficient operation of the equipment.
2. Lubrication Between Jaw Crusher Components
Regular lubrication between the machine's components is essential. Proper lubrication not only ensures normal operation but also significantly extends the service life of the equipment. Lubricants should be selected based on the actual working environment of the equipment. When possible, it is recommended to use specialized lubricating grease. During oil replacement, clean the bearings thoroughly with clean gasoline or kerosene, then fill the bearing housing with grease, typically about 50% of its volume.
3. Periodic Adjustment of the Jaw Crusher
Users should regularly adjust the gap between the rotor and the impact plate to effectively control the discharge particle size and ensure high-quality output. Additionally, the gap between the bottom of the feed opening and the jaw plate should also be adjusted periodically. This requires removing the square steel on both sides of the frame, rotating it after pulling it out, and then reinserting it.
4. Repair of the Jaw Crusher
Maintenance of the jaw crusher also includes timely repair when issues arise. If any problem occurs, users must repair the equipment promptly to maintain normal operation and extend its service life.
Conclusion:
Regular maintenance and inspection of the jaw crusher are extremely important. It is recommended that users perform routine servicing. For more detailed information about jaw crusher maintenance and repairs, users are welcome to consult customer service online for free.
