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.
