Vertical Grinding Mill (Coal Pulverizer) Explained - saVRee

Grinding is often referred to as 'size reduction'. Classifying occurs in order that pulverized coal reaches the desired fineness prior to entering the furnace. Larger particles are returned to the grinding area where they are further reduced in size until they are small enough to pass through the classifier. Coal pulverizers increase the cross-sectional area and dryness fraction of coal prior ...
