A Comparison of Three Types of Coal Pulverizers

+

The vertical roller mill (VRM) shown in Figure 4 is an air swept, mediumspeed, vertical pulverizer with integral classifier. It pulverizes coal by applying hydraulicallyloaded grinding pressure through three grin ding rollers onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal grindability and desired product fineness. Raw coal is fed through a ...
