VRM The Latest Technology Bashundhara CementCement grinding Vertical roller mills versus ball mills

The VRM is a vertically placed large sized machine which is equipped with some rollers used for grinding raw material It also consists of one table which is rotated by electrical motor raw materials are feeded on the table Due to centrifugal force on the table raw material goes below the rollers a gap between roller table has to be A stable grinding bed is usually easily obtained in raw material grinding in a vertical roller mill with a high efficiency separator However in cement grinding it becomes more difficult to form a stable grinding bed as • cement is ground much finer than raw meal • the feed to a cement mill is often completely dry and is significantly more
