The coal flow is controlled by the feeder, allowing coal to flow into the pulverizer mill. The pulverized coal and air mixture is then transported from the mill outlet to the exhauster. From the exit of the exhauster, the coal and air mixture flows to the distributor box or riffle. From the riffle, the coal and air flow to the boiler burner panels.
