Raw coal is fed to pulverizer from the coal feeder via a center feed pipe. The coal is grounded between the three grinding rollers and the rotating table in the pulverizer. Pulverized coal is simultaneously dried by the drying gas fed from bottom part of pulverizer and carried into the separator fixed at the top of pulverizer.
Properly sized pulverized coal exits the classifier into coal piping for transport to the furnace. Oversized pro- duct is, however, separated and returned to the mill for further grinding. There is minimal metal-to-metal contact of the grinding elements in the BTM resulting in very little wear and low maintenance.
