Coal Mill an overview | ScienceDirect Topics
In coal milling for power stations, a ‘closedloop’ process is used in which the rejects from the classifier are returned to the mill for regrinding In VSMs, the recirculation loop is within the mill, but some mill types would have an external loopAll internal mill surfaces must be smooth so that the swirl of the coal/air mixture may enter and leave the classifier without spoiling or turbulence caused by double layer tiles, welded pad eyesCoal Pulverizer Maintenance Improves Boiler Combustion
