Abstract

By supplying hot gas to a mill inlet in a vertical roller mill, a prescribed pre-heating time is applied and pre-heating occurs so as to achieve a prescribed supply start inlet temperature at which the discharge gas temperature at the mill outlet is at least 65°C and the hot gas temperature at the mill inlet is 150–250°C. After pre-heating, high moisture content coal supply to a rotating table is started and at least either the flow rate or the temperature of the hot gas supplied to the mill inlet is adjusted such that the temperature of the discharge gas at the mill outlet is maintained at 65–100°C.
