The roller bearing is the core component of ultrafine vertical mill. It runs in a complex environment of high temperature, impact, heavy load, and low speed. Therefore, various failures will occur if it is not properly maintained.

In particular, the abnormal temperature of the roller bearing will cause the electric switch of ultrafine vertical mill to be cut off frequently, which will seriously affect the production schedule. Today, the editor summarized the common causes and treatment methods of abnormal grinding roller bearing temperature, hoping to help everyone's production.
