Roller mill tests can help determine the right roll speed ratio for your material. Roll gap. Controlling the roll gap (Figure 3) is critical to achieving your required final particle size. This control has two components the roll gap size and roll alignment. The roller mill operator can control the particle size by widen-ing or narrowing the.
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.
