Pulverizer - Wikipedia

Vertical spindle roller mill 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.

Coal fired power plant - Energy Education

Once unloaded, the coal is then pulverized into a fine powder by a large grinder. This ensures nearly complete burning of the coal in order to maximize the heat given off and to minimize pollutants. The pulverized coal is then input to a boiler, where combustion occurs and the coal provides heat to the power plant.
