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 gravityfed through a central feed pipe to the grinding table where it flows outwardly by centrifugal action and is ground between the rollers and table.

modular roller mill design, the same grinding roller modules are used for both raw and cement mills, and parts commonality is achieved. Furthermore, by matching mill power and table rotation speed, identical reduction gear units are used on the three VRMs: one set of 5roller raw mills, and two sets of 6roller cement mills.
