Overheating Fault Of Bearing Shell

[gjsohcat]

Bearing bush is the key part of vertical roller mill. The problem often occurs is that the temperature is overheated, which leads to the performance disorder. Generally speaking, its complexity mainly involves the following conditions:

In view of the typical faults encountered in the production of vertical roller mill, this paper analyzes the causes in detail and gives the targeted technical treatment measures.

The Gap Between The Hollow Shaft At The Entrance End Of Raw Materials Is Small

About 90% of the power of the required abrasive in the vertical roller mill will be converted into heat energy. This is a part. Combined with the temperature of the abrasive, the joint action of the two causes the axial thermal deformation of the cylinder body, which leads to thermal expansion and the phenomenon of cooling shrinkage caused by shutdown. These factors may cause the bearing shell to have a heating condition due to axial force.
