Cause Analysis:

Roller bearings pay special attention to the quality of the bearings, but they will also experience local damage during long-term operation, such as ball wear, loose joints, and so on. At this time, the temperature of the roller bearing will definitely be abnormal.

Approach:

When the surface of the grinding roller bearing is uneven, local rotation is blocked, the left and right swing amplitude is increased, and internal noise occurs; or the bearing temperature is overloaded or fluctuates at the moment when ultrafine vertical mill is turned on, the production should be stopped immediately, and maintenance inspection or disassembly should be carried out. , If the damage is serious, the grinding roller bearing should be replaced in time to ensure production safety.
