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.

Effects of Mill Performance on Unburnt Carbon in Coal ...
2017-12-1 As a result, the coal particles were coarser. More than 50% (by weight) particulates were within a 75 to 300 μm size range when sampled from Mill 20 and 40. There is also a mal-distribution of coal mass flow from the four PC pipes leading into the burners of the boiler. This caused a high rear pass temperature in the burner.
