2. The hot air is used for transportation of the recirculating coal within the mill and also for transporting the coal from the pulverizer to the furnace. As the coal is continuously reduced in size, the smaller/lighter particles are swept from the bowl by the hot air. Hot air (and cool tempering air) is provided by the primary air fans.
Mill Rejects from coal mill will drop into the Pyrite Hopper through the grid. Oversize material will be retained on the grid. A pneumatic cylinder operated Plate Valve on oversize material discharge chute will be provided, which will be operated automatically in case of accumulation of oversized rejects.
