Check the lubrication points in ball mill and make sure the lubrication oil meets requirements.
2. The lubrication oil or grease goes bad. Operators should change them.
3. There might be blocking in the lubrication line or the lubrication oil does not directly enter the lubrication points. To solve this problem, operators should check the lubrication line and remove the impurities blocked.
4. The oil film covers the bearing bush is not even. To solve this problem, operators should adjust the side gap between bearing bush and bearings.
5. The lubrication oil/grease in ball mill is too much, and they form rolling element, which produces much heat. To solve this problem, operators should reduce some lubrication oil/grease.
