Similar to the ring and ball mill, the vertical spindle roller mill uses large "tires" to crush the coal. These mills are usually found in utility plants. Raw coal is gravity-fed through a central feed pipe to the grinding table where it flows outwardly by centrifugal action and is ground between the rollers and table.

In coal pulverizers of the vertical spindle type, hardened grinding elements are used for the fine crushing of coal. The hardened grinding elements may vary in design, but all are intended to capture raw unground coal particles between two hardened surfaces. The grinding elements crush the raw coal particles in a bowl during normal mill operation.

Coal from the boiler bunkers is fed under control into the mills, the feed rate being determined by the requirements for steam. Inside the mills either large steel balls or rollers run in circular tracks, to pulverise the coal to powder. This fine, highly combustible powder is blown from each mill into the boilers at some 63 tons an hour.
