Maintenance and repair
The maintenance and repair of ball mills is a regular task, and the quality of the repair work directly affects the operation rate and service life of the ball mill. Therefore, how to properly maintain and repair the ball mill during use is introduced below:
1. All lubricating oil should be completely drained, thoroughly cleaned, and replaced with new oil when the mill is put into continuous operation for one month. In the future, it is recommended to change the oil every 6 months in conjunction with Zhongxiu.
2. Check the lubrication condition and oil level of each lubrication point at least once every 4 hours.
3. During the operation of the mill, the temperature rise of the main bearing lubricating oil shall not exceed 55 ℃.
4. During normal operation of the mill, the temperature rise of the transmission bearings and reducer shall not exceed 55 ℃, with a maximum of 60 ℃.
5. The transmission of large and small gears is smooth without any abnormal noise. If necessary, the gap should be adjusted in a timely manner.
6. The ball mill runs smoothly without strong vibration.
7. The motor current should have no abnormal fluctuations.
8. All connecting fasteners are not loose, and there is no oil leakage, water leakage, or mineral leakage on the joint surface.
9. Steel balls should be added in a timely manner according to their wear and tear.
10. If any abnormal situation is found, the grinding should be stopped immediately for maintenance.
11. The mill liner should be replaced when it is worn by 70% or has a 70mm long crack.
12. When the lining bolts are damaged and cause the lining to loosen, they should be replaced.
13. When the main bearing is severely worn, it should be replaced.
14. When the grate plate of the grid ball mill is worn out and cannot be welded, it should be replaced.
15. After the gear surface of the large gear is worn to a certain extent, it can be flipped over and continue to be used.
16. The small gear is severely worn and should be replaced.
17. When the spiral of the incoming and outgoing materials is worn, it should be welded and repaired in a timely manner. If it is worn to the point where it cannot be welded and repaired, it should be replaced.
18. Loose or damaged anchor bolts should be repaired in a timely manner.
The maintenance of the ball mill is a regular task, and the quality of the maintenance work directly affects the operation rate and service life of the ball mill. In order to timely detect defects and eliminate hidden dangers to ensure the normal operation of the grinding machine, in addition to daily maintenance, it is also necessary to regularly stop grinding (recommended once a month) and carefully inspect important components such as hollow shafts, main bearings, cylinders, reducers, and large and small gears, and make detailed records. Handle and arrange intermediate and major repairs according to the severity of defects.
