The raw coal enters the mill via a feed screw and is discharged onto the rotating grinding table. The rotation of the table accelerates the flow of material towards the grinding track, where the coal is ground between the table and the three rollers.
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 it is collected.
