Trunnion bearings in cement and grinding mills are exposed to extremes in heat, cold, rain and harsh airborne particulates. To help protect bearings against these extreme conditions and avoid possible production headaches, large amounts of grease are used to purge contaminants from trunnion housings.
An essential part of a mill head is its trunnion bearings that provide support for the revolving material in the mill. ... On their interior walls, there are a lot of flat balls. They are different from roller mills in that they don't have a separate cooling system for the welded arc, which means a third cooling source is needed. ...

When it comes to the mechanical components of ball mills which are essential to any hard rock mining operation the focus is often on the trunnion bearings. With diameters typically ranging from one to two metres, these bearings tend to steal the show.
Trunnion bearings are used in cement mills to support rotating drum of the cement mill and are often located at the discharge end of the mill. The purpose of the trunnion bearings is to provide a ...
Depending upon available handling facilities, the head or shell can be lined separately ina repair bay, or alter assembly of the mill proper in the trunnion bearings. In the case of ball mills, all internal wearing parts will pass through the manhole, whereas in the case of open end rod mills they sill pass through the discharge trunnion opening.
