Review on vertical roller mill in cement industry & its

For the past three decades the vertical roller mill has emerged to be the preferred choice for grinding raw materials. With the grinding capacity of a vertical roller Vertical roller mills (VRM) have been used extensively for comminuting both cement raw materials and minerals like limestone, clinker, phosphate, manganese, magnesite, feldspar and titanium. These mills combine crushing, grinding, classification and drying operations in one unit and have advantages over conventional machines and Copper ore grinding in a mobile vertical roller mill pilot plant
