Coal Mill - an overview ScienceDirect Topics

In coal milling for power stations, a ‘closed-loop’ process is used in which the rejects from the classifier are returned to the mill for regrinding. In VSMs, the re-circulation loop is within the mill, but some mill types would have an external loop. In fact, there are a number of re-circulation loops within a mill system.

Pulverizer - Wikipedia

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.
