Milling process in vertical mill the coal feeder discharge spout is connected to the inlet pipe located centrally in the mill and discharges onto the rotating table. thus the crushed coal of 50 mm size lands at the center of the grinding table at the start of the.
The coal then continues over the dam ring and is entrained in the hot drying air that enters the mill house through the nozzle ring. the air lifts the coarser particles back onto the grinding table and sweeps the finer particles up into the separator. when the final product leaves the mill with the air, it goes to a cyclone or bag filter, where.
