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.

Coal mill pulverizer in thermal power plants

Nov 17, 2012  4.4.Classification The circulating air is also used to classify the pulverized coal product prior to carrying it to the burners. The classifier, located on the top of a mill returns the over-size material back to the pulverizer but allows the proper-sized material to pass out of the mill to the burners. classifiers
