Coal Millan 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.
