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

The finely ground material discharges along the outer periphery of the ball races. For the pulverization of coal, hot air, introduced between the lower race and the pulverizer housing, lifts or carries the fines to a cyclone classifier at the center of the pulverizer. ... Counterrotating top and bottom rings also are used to increase pulverizer ...
