A Comparison of Three Types of Coal Pulverizers

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

Vertical Grinding Mill (Coal Pulverizer) Explained

Coal Pulverizer Inlets and Outlets Louvres ( nozzle ring ) around the outer perimeter of the grinding table allow hot gas to flow into the grinding mill through the mill base. Some of the pulverized coal is transported from the base of the mill up to the classifier by the hot gas stream i.e. the coal is transported pneumatically.

Dynamic classifiers improve pulverizer performance and …

A dynamic classifier has an inner rotating cage and outer stationary vanes which, acting in concert, provide centrifugal or impinging classification. Replacing or upgrading a pulverizer's classifier from static to dynamic improves grinding performance reducing the level of unburned carbon in the coal in the process.
