Cement grinding Vertical roller mills versus ball mills

mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the majority of the particles in the bed are considerably smaller than the thickness of the bed. It is thus necessary that a stable and consistent ...

Vibration Due To Shaft Misalignment | .

Vibration in one radial direction may be very different in amplitude when compared to vibration in another radial direction. This is one instance where amplitude readings are not only helpful in detecting a problem but also helpful in diagnosing a problem. Misalignment can result in a machine having high vertical vibration on one end and high horizontal vibration on the other with other radial ...
