How does a coal mill in a thermal power plant work? - …
Power plants generally use steam coal which is a grade between anthracite and bituminous. Coal is first milled to a fine powder, which increases the surface area and allows it to burn more quickly. In these pulverized coal combustion systems, the powdered coal is blown into the combustion chamber of a boiler where it is burnt at high temperature.

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.
