Check for loose screws before starting, monitor temperature and lubrication during operation, and replace worn parts promptly after shutdown—master these seven maintenance tips and you can extend the life of your impact crusher by 30%.

Impact crushers are primarily used for secondary crushing in sand and gravel production lines and are crucial equipment. Over extended operation, crushers frequently come into contact with hard stone, causing significant wear and tear. This article discusses how to maintain and maintain impact crushers during operation.

1. Before starting the equipment, inspect all parts of the machine for loose screws or missing parts. Repair any problems promptly to ensure the equipment is functioning properly before starting.

2. Before starting the machine, manually rotate the rotor to ensure it rotates freely and avoids friction with other components.

3. When starting the machine, follow the correct sequence: start the machine first, then feed. Similarly, when shutting down the impact crusher, follow the same sequence: stop feeding, then shut down.

4. While the machine is running, observe the operating sound, current, voltage, vibration, and temperature to ensure they are normal. Generally speaking, the machine's rotor bearing temperature should not exceed 60°C, and the maximum should not exceed 75°C. If the temperature exceeds these limits, the machine should be shut down immediately for inspection.

5. While the machine is running, ensure that the material feed is even and avoid sudden increases or decreases that could cause unstable machine load. If any unusual noises are heard during crushing, the machine should be shut down for inspection.

6. Always monitor the machine's lubrication system and regularly replace the lubricating oil and grease. Grease the bearing housing at least once a month, and replace the lubricating oil and felt every three months.

7. When the machine is shut down, inspect vulnerable parts for wear. If severely worn, replace them promptly.
