The grinding pressure is set too large or too small, or the normal pressure in the normal production due to insufficient and unbalanced nitrogen gas pressure causes the upstream and downstream movements of the grinding roller to cause vibration. The treatment measures are: adjust the pressure and check the nitrogen pressure.

The retaining ring is too low to maintain a certain layer of material, and the material is thin and causes vibration; the retaining ring is too high, the material is thick, the air volume is reduced, the discharging is not smooth, and the differential pressure is high, causing vibration.

In the vertical mill production process, excessive vibration is a common fault. The reasons and solutions for excessive vibration are as above, and I hope to help users.
