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.

by reducing the grinding force against the mill table. With sufficient high pressure on the piston bottom face, the rollers can even be lifted off of the grinding table segments, which results in a significant wear reduction between the rollers and grinding segments, as well as minimal mill torque requirement during mill …

According to the rotating speed of the grinding parts of the coal mill, the coal mill can be divided into a low-speed coal mill, a medium-speed coal mill, and a high-speed coal mill. The air-swept ball mill is a kind of low-speed coal mill.
