Operational parameters affecting the vertical roller mill
Vertical roller mills (VRM) have found applications mostly in cement grinding operations where they were used in raw meal and finish grinding stages and in power plants for coal grinding. The mill combines crushing, grinding, classification and if necessary drying operations in one unit and enables to decrease number of equipment in grindingMany materials can be ground in vertical roller mills such as: * raw materials * coal * pozzolana / trass x slag * (cement) This paper deals in first place with roller mills for raw material processing. For grinding coal, slag, cement, etc., adaptations to mills and systems have to be made. 2. FUNCTIONS OF THE ROLLER MILLHolderbank Cement engineering book Archive
