Coal Mill | PDF | Mill (Grinding) | Screw

It is driven by a planetary gearbox. The three grinding rollers, mounted in fixed position, are passed down on the table under hydraulic loading. Raw coal enters through the center of the mill and is deposited on the grinding table. Centrifugal force feeds the coal radially outward where it is ground between the roller tyres and grinding track.

Vertical Grinding Mill (Coal Pulverizer) Explained - saVRee

Raw coal (sometimes pre-treated) is fed into the centre of the grinding table. The grinding table rotates which causes the coal to move towards the outer periphery of the grinding table. The coal is ground between the rollers and grinding table. When enough coal has been reduced in size, it will flow over the top of the dam ring (retention ring).
