Review on vertical roller mill in cement industry & its
Vertical Roller Mills (VRM), High Pressure Grinding Rolls (HPGR), Vertical Shaft Impact Crushers (VSI) and more recently, Horizontal Roller Mill (Horomill) have saved the specific power by 45–70% when compared with a ball mill circuit [8], [10]. Now a days Ball mills and HPGR are installed together as a common unit.Proven commercially, the OK™ mill is the premier roller mill for finish grinding of Portland cement, slag and blended cements. The mill consistently uses five to ten percent less power than other cement vertical roller mills, and in comparison with traditional ball mill operations, the energy requirements for the OK cement mill isOK™ cement mill The most energy- efficient mill for
