Talking about ten tips for maintaining the ball mill

The ball mill is the key equipment for crushing the material after it is crushed. It is suitable for grinding various ores and other materials. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal dressings. As well as glass ceramics and other production industries, dry or wet grinding of various ores and other grindable materials is one of the high-fine grinding machines widely used in industrial production. Due to the requirements and strength of their work, It is very important that the ball mill performs routine maintenance. In particular, the replacement and maintenance of lubricating oil is especially important.

1. All lubricating oil should be completely discharged when the mill is put into continuous operation for one month, thoroughly cleaned and replaced with new oil. In the future, the oil will be changed every 6 months in conjunction with the medium repair.

2. The lubrication condition and oil level of each lubrication point should be checked at least every 4 hours.

3. When the mill is running, the temperature rise of the main bearing lubricant does not exceed 55 °C.

4. When the mill is in normal operation, the temperature rise of the transmission bearing and reducer does not exceed 55 °C, and the maximum does not exceed 60 °C.

5. The mill liner should be replaced when it is worn 70% or has a crack of 70mm length.

6. When the lining bolt is damaged, the lining should be replaced when it is loose.

7. The rafter plate of the lattice ball mill should be replaced when it can no longer be repaired.

8. There is no looseness in each connecting fastener, no oil leakage on the joint surface, no leakage of water, no leakage.

9. If abnormal conditions are found, they should be stopped and repaired immediately.

10. After the gear surface of the large gear is worn to a certain extent, it can be turned over to continue to use.

A regular job in the maintenance of the mill. The quality of the maintenance work directly affects the operation rate and service life of the energy-saving ball mill. In order to find out the hidden defects in time to ensure the normal operation of the mill, in addition to daily maintenance, it is also necessary to stop the grinding regularly. (Recommended once a month) for important components such as hollow shafts, main bearings, cylinders, reducers, The large and small gears are carefully checked for detailed records. According to the defect situation, prioritize and arrange the intermediate repair and overhaul plan.
