A Comparison of Three Types of Coal Pulverizers. 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.
It is driven by a planetary gearbox. The three grinding rollers, mounted in fixed position, are passed down on the table under hydraulic loading. Raw coal enters through the center of the mill and is deposited on the grinding table. Centrifugal force feeds the coal radially outward where it is ground between the roller tyres and grinding track.
