Internal pulverizer components can be protected from erosion by using CeraVAM lining, a highdensity alumina ceramic. Ceramiclined panels are available for the pulverizer housing, turret, classifier cone and roll wheel brackets (Figure 7). Special panels can be made to protect just about any internal pulverizer component.

The BTM is a lowspeed mill that primarily grinds coal by impact and attrition. The VRM is a medium speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed

The main source of heat is coal burning. Coal is fired as a main fuel () in the rotary kiln and calciner chamber. Coal is burnt to provide the required heat for calcination and to convert the kiln feed into clinker. This red hot clinker further goes to clinker cooler for cooling the clinker from 1400 degrees to 200 degrees.
