Our flagship mills are centrifugal ring-roll pulverizers – equipped with three pendulum roll assemblies suspended from a rotating carrier. Leveraging centrifugal force created by the rotation of the carrier, the roll assemblies swing outward causing the roller at the bottom of the roll assembly to rotate against the inside of the stationary ring.

The BTM is a low-speed 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
