1. Regularly check whether the parts of the equipment are loose, and tighten timely if they are loose; Regularly check the use of vulnerable parts such as hammer head and lining board. This can extend the life of the machine, reduce maintenance costs of sand washing machine.

2. Keep the lubrication system in good condition: we should often examine case of lubrication, the temperature of the rotor bearing should be kept below 60 ℃, the highest temperature should not exceed 70 ℃, if it is found that the temperature is too high, we should find out the reason, take timely measures to eliminate. In addition, according to different requirements to choose lubricating materials, some bearings need to add lubricating oil, some may require adding lubricating grease, this should be selected according to requirements.

3. Keep the equipment clean: in ordinary maintenance, the surface of precision parts should be carefully protected to prevent dust pollution and damage. If the hammer crusher is stored for a long time, it is best to apply oil or rust inhibitor on the surface to prevent the rust from affecting the normal operation.

4. Maintenance details during loading and unloading: when loading and unloading the parts of hammer crusher, there must be copper rod or corresponding cushion block. It is not allowed to hit directly with hammer to prevent damage and crack. If the bearing of the hammer crusher is damaged, it is better to replace two bearings at the same time. If only one bearing is replaced, it should be removed completely and cleaned before installing.
