More## Cement grinding Vertical roller mills versus ball mills

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 grinding bed is formed between the rollers and the table of the vertical roller mill ...
