The dried coal is sent to pulveriser mill. Pulverized coal is supplied to a cyclone separator where the transporting air is separated and the required sized coal is transferred to pulverized coal bin with the help of screw conveyor. The feeder receives the primary air from a fan and the mixture of pulverized coal and air is supplied to the burners.
