A cement vertical roller mill (VRM) is a type of grinding equipment commonly used in cement plants for raw material grinding and cement grinding. It is an energy-efficient alternative to traditional ball mills, as it utilizes rollers to grind and crush the materials between a rotating grinding table and a set of rollers mounted on a vertical axis.
