    Coal Pulverizer Pall

    The four most common types of coal pulverizers are: Ball-Tube Mills. This type of mill consists of a rotating tube filled with cast alloy balls. Coal is introduced through two hollow trunnions on each side of the tube. As the tube rotates, the balls tumble onto the coal, crushing and pulverizing it. Impact Mills.

    A control circuit monitors the coal level in the mill, and controls the speed of the raw coal feeder to maintain it. Maintaining the coal level in the mill offers a built-in capacity cushion of pulverized fuel to take care of short interruptions in the raw coal circuit. The mill is pressurized and the air-tightness is ensured by plenum chambers around the rotating trunnion filled with pressurized seal air.
