Maintenance and Care of Ball Mills

During the use of a ball mill, wear, loosening of connections, oil deterioration, and corrosion of metal structures inevitably occur. These issues can lead to a decline in the mill’s technical, economic, and safety performance. Therefore, regular maintenance and care of ball mills are essential before the wear of mill components affects production efficiency. This helps prevent and eliminate potential hazards, ensuring the ball mill remains in good working condition.

As a routine procedure, combine the inspection, maintenance and care of ball mills with regular overhauls. Assign dedicated personnel to tasks such as inspection, lubrication, and cleaning. During the maintenance process, operators need to focus on the following areas:

Perform regular daily inspections of the ball mill

After the ball mill’s first use and continuous operation for one month, replace the lubricating oil. Drain out all old oil and add new oil. Afterward, change the oil every six months of operation.

During operation, regularly monitor the lubrication condition of each lubrication point, including the lubrication status and oil level.

During operation, keep the temperature of the main bearing lubrication oil, drive shaft, and gearbox below 55°C.The temperature should not exceed 60°C. If it does, stop the mill and perform a thorough inspection.

During operation, the ball mill should run smoothly without abnormal vibrations or noises. If any of these issues are detected, promptly inspect and adjust the ball mill.

Regular maintenance should include checking the condition of fasteners for looseness or wear. Additionally, inspect joint surfaces for oil, water, or ore leakage.

Regularly monitor the wear condition of the steel balls or steel rods used in the ball mill. Replace them when wear is significant.

When the wear of the mill liners reaches 70%, plan for their replacement. If the bolts securing the liners show severe wear or loosening, replace them promptly.

Regularly inspect the wear of the ball mill’s large gears. If they are severely worn or damaged, replace them in a timely manner.

Check the inlet and outlet spiral pipes regularly. If they are slightly damaged, repair them. If severely damaged beyond repair, replace them immediately.

For grid-type ball mills, replace the grate plate when it can no longer be repaired.

Periodically check the condition of the ball mill’s anchor bolts. If any are loose or damaged, handle them promptly.

Conclusion

Regular maintenance and care of ball mills can significantly extend the equipment’s lifespan and ensure the production efficiency and quality of the product.
