Sep 20, 2018 · 1.The bearing of grinding roller and bearing should be added oil regularly. 2.If the vertical roller mill is in bad quality, the temperature will also rise. 3.The room temperature of cement vertical roller mill can not over 70℃, if the temperature of bearing is over-heated, we should demount it and clear the bearing and bearing room.

Temperature Of Vertical Roller Mill

Vertical mill roller bearings have a relatively high operating temperature, and the internal temperature of the bearing is close to 200 ° C. If the type of lubricating oil is not correct, the oil used for lubrication will deteriorate or be evaporated due to high temperature and high pressure, thus losing the roller bearing.
