What are the key points of sand mill maintenance?

1. Regular cleaning:
Clean the inside of the grinding cylinder to remove residual materials and grinding media.
Clean the feed port, discharge port and sealing parts to prevent blockage and leakage.
2. Check the grinding media:
Check the wear of the grinding media regularly. If it is damaged or severely worn, replace it in time.
Ensure the filling amount of the grinding media is appropriate.
3. Lubrication maintenance:
Regularly lubricate the transmission parts such as motors, reducers, bearings, etc.
Select suitable lubricants and add or replace them according to the prescribed cycle.
4. Seal inspection:
Check the status of mechanical seals and oil seals. If there is leakage or damage, repair or replace them in time.
5. Motor and electrical inspection:
Check the operating status of the motor, including temperature, sound, current, etc.
Regularly check the connection and working status of electrical components to ensure safety and reliability.
6. Check the agitator shaft and dispersion disc:
Check whether the agitator shaft is bent or worn, and whether the dispersion disc is damaged.
If there is any abnormality, repair or replace it in time.
7. Cooling system maintenance:
Ensure that the cooling system is unobstructed, without blockage and leakage.
Check whether the temperature and flow of the coolant are normal.
8. Regular tightening:
Check whether the bolts and nuts at each connection are loose and tighten them in time.
9. Filter system cleaning:
Clean the filter devices for feeding and discharging to ensure the normal circulation of materials.
10. Operation specification training:
Train the operators to ensure that they use the equipment according to the correct operating procedures.
