Ball Mills - an overview | ScienceDirect Topics
2.10.2 Vertical Mills. For more than 50 years vertical mills have been the mill of choice for grinding raw materials into raw meal. More recently they have become widely used for cement production. They have lower specific energy consumption than ball mills and the separator, as in raw mills, is integral with the mill body.

The Design of Rolling Bearing Mountings
mill rotors are mounted on spherical roller bearings. This self-aligning bearing type can compensate for mis-alignments of the two plummer block housings, and possible rotor deflections. Two spherical roller bearings FAG 23228EASK.M.C3 are mounted, one acting as the locating bearing, the other one as floating bearing.

An Overview of Bearing Vibration Analysis
result bearing manufacturers have developed vibration tests as an effective method for measuring quality. A common approach is to mount the bearing on a quiet running spindle and measure the radial velocity at a point on the bearing's outer ring in three frequency bands, 50-300, 300-1800 and 1800-10000Hz. The bearing must meet RMS velocity ...
