    Coal Mill. Coal mill is used to grind pulverize and dry coal before the coal is transmitted the boiler. It is an important auxiliary machine for coal-powder furnace. It has three methods to produce coal powder --- crushing impacting and grinding. A grinding table rotates round a vertical axis. 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.
