How to maintain a ball mill

1. Daily Inspection

Check the motor, coupling, and reducer for abnormal noise or vibration.

Inspect lubrication system: oil level, oil pressure, temperature, and no leakage.

Check bolts and liners for looseness or damage.

Monitor bearing temperature (normally ≤70°C).

Check feed and discharge for blockage.

2. Lubrication Maintenance

Use specified grease and lubricating oil.

Regularly replace oil and clean oil filters.

Avoid insufficient or excessive lubrication.

3. Liner & Grinding Media Management

Replace worn or broken liners in time.

Check and supplement steel balls/grinding media regularly.

Avoid running empty for a long time to prevent damage.

4. Transmission System

Check V-belts or gears for tension, wear, and alignment.

Keep the coupling in good condition.

5. Lubrication & Cooling

Ensure cooling system works normally to prevent overheating.

Clean dust and debris around the mill regularly.

6. Safety

Cut off power before maintenance.

Do not stand near the feeding or rotating parts during operation.

If you want, I can also give you a simplified version for operator training or a monthly/yearly maintenance checklist.
