Precautions For Maintenance Of Grinding Roller Bearings

[gjsohcat]

Ensure the normal operation of the sealed fan. The wind pressure should not be lower than the specified value. Under normal circumstances, it should be kept above 20Bar. Regularly check whether the sealed air duct is damaged; the joint bearing at the joint between the sealed air duct and the vertical roller mill in the grinding cavity Whether the flange is disengaged, etc.

At the same time, in order to ensure that the positive pressure air entering the vertical roller mill is clean, a filter screen and filter cloth must be installed at the entrance of the fan to prevent micro-particle materials from entering the sealing air cavity of the vertical roller mill, damaging the sealing ring and oil seal of the vertical roller mill, and causing the vertical roller mill Oil spill.

The vacuum degree of the oil return pipe of the vertical roller mill determines the oil level in the vertical roller mill cavity. In order to keep the oil level in the vertical roller mill relatively stable, the adjustment of the vacuum degree and pressure must be cautious. It is directly related to the lubrication state of the vertical roller mill bearings.
