How to maintain an impact crusher

The maintenance of an impact crusher is the key to ensuring its efficient, stable operation and extending its service life. The following are some specific maintenance measures:

1. Routine inspection and maintenance
Daily inspection: After each shift, the impact crusher should be fully inspected, including the tightening of fixed parts, belt drive, bearing seals, electrical switches, etc. After about two weeks of operation, it can be switched to a comprehensive inspection once a month.
Regular inspection: Regularly check the operation of each component of the impact crusher, whether the seals are damaged, whether the lubrication is good, etc. Any abnormal situation should be handled in time to ensure the normal operation of the equipment.
2. Cleaning and maintenance
Surface cleaning: Regularly clean the surface and interior of the impact crusher to remove dust, debris and dirt. Keeping the equipment clean helps improve work efficiency and extend the service life of the equipment.
Internal cleaning: Choose a suitable cleaning fluid for internal cleaning. You can use manual cleaning (wiping and spraying) or mechanical cleaning (boiling cleaning, vibration cleaning and ultrasonic cleaning).

3. Lubrication and adjustment
Lubrication maintenance: Keeping the impact crusher well lubricated is an important part of maintenance. Lubricating oil should be checked and replaced regularly to ensure that the equipment is in good lubrication condition and avoid component wear and friction. It is recommended to add grease to the bearing seat at least once a month, and replace the lubricating oil and oil felt every three months.
Gap adjustment: Regularly adjust the gap between the impact crusher rotor and the impact liner to effectively control the size of the discharge particle size and provide users with high-quality materials. When adjusting, the screw sleeve should be loosened, the long nut should be turned, and the screw sleeve should be tightened after adjustment.
4. Replacement of wearing parts
Inspection of worn parts: Regularly check the working parts of the impact crusher, such as plate hammers, impact plates, etc. If severe wear is found, they should be replaced in time. This helps to maintain the crushing efficiency and production capacity of the equipment.
Replacement of seals: Regularly check the seals. If wear, aging or damage is found, they should be replaced in time. This can ensure the sealing performance of the equipment and avoid leakage and pollution.

5. Preventive maintenance
Pre-startup inspection: Before starting the equipment, check the parts of each part of the machine to ensure that there are no loose screws, missing parts and other problems. At the same time, the rotor should be turned manually to ensure that the rotor can rotate flexibly and will not cause friction with other parts.
Startup and shutdown sequence: Start and shut down the equipment in the correct order, that is, start the machine first and then feed, and stop feeding first and then shut down. This helps to reduce the impact and wear of the equipment during startup and shutdown.
Operation monitoring: When the equipment is running, pay attention to whether the machine’s operating sound, current, voltage, vibration temperature, etc. are normal. If any abnormality is found, the machine should be stopped immediately for inspection and treatment.
In summary, the maintenance of the impact crusher needs to start from multiple aspects, including routine inspection and maintenance, cleaning and maintenance, lubrication and adjustment, replacement of wearing parts, and preventive maintenance. Through the implementation of these measures, the stable operation of the impact crusher can be ensured, the work efficiency can be improved, and the service life of the equipment can be extended.
