VRM-Process Parameters in Vertical Roller Mill

The material , which flows over the damn ring is caught by the vertical gas flow from the nozzle ring and lifted up and the coarse particles falls through reject chute Nozzle Ring Angle The nozzle ring angle is usually kept 60 degree for proper air flow Air flows at a velocity of 45 m/s the angle plays a vital role in material circulation inside the millVertical roller mill optimisation - News, Events & Training,Vertical roller mills (VRMs) have become the equipment of choice for raw and solid fuel grinding in cement factories Increasingly modern cement plants also use VRMs for cement grinding However, opportunities for the optimisation of VRMs are less obvious than with ball mills as all processes of grinding, drying, classification and regrinding take place within the body of the millCement grinding Vertical roller mills versus ball mills,vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the majority of the particles in the bed are considerably smaller than the thickness of the bed
