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 4570% when compared with a ball mill circuit [8], [10]. Now a days Ball mills and HPGR are installed together as a common unit.
