Scale-up criterion is the net specific power consumption, i.e. the power consumed by the mill rotor itself minus all mechanical and electrical losses divided by the feed rate of solids. For the full scale mill, specific power is multiplied by the feed rate to get the net mill power.Vertical Roller Mill The vertical roller mill (VRM) shown in Figure 4 is an air swept, medium-speed, vertical pulverizer with integral classifier. It pulverizes coal by applying hydraulically-loaded grinding pressure through three grin- ding rollers onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal.
