Oil Seal Of The Grinding Roller

[gjsohcat]

The sealing air system is a key link to ensure that the oil seal of the grinding roller is not damaged. The sealed air system consists of a sealed fan and an air duct. The blown wind starts from the sealed fan and finally reaches the sealed air duct. The grinding roller installed on the grinding disc of ultrafine vertical mill seals the air to form a space.

In this way, an annular seal cleaning system can be formed, which can not only ensure that the powder does not enter the roller bearing, but also prevent the powder from damaging the oil seal. All links are closely connected, and one is indispensable.

If any link has problems, air leakage or debris in the air duct, the pressure of the air seal ring will be reduced, and the air volume will be insufficient, so that the annular air seal system cannot A series of conditions are formed, which in turn causes oil seal damage, powder ingress, and bearing temperature rise.
