Vertical Mills comprise 2-4 conical rollers which are hydraulically pressed onto a horizontal rotating grinding table. Material is directed onto the centre of the table and is thrown outward by rotation under the rollers. Fines pass out with the air current while coarse material falls back onto the feed table. A major cause of material instability is fine, dry mill feed which can usually, be ...

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.
Abstract 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 grinding circuits.

The material buffering capacity between the grinding disc and the grinding roller is insufficient, and it is easy to produce vibration. During the trial production of vertical mills, due to mechanical requirements requiring 70% feed, the feed is too small, which is one of the reasons for the large vibration of the vertical mill in trial production.
