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.
They also used more coal than any other state per capita — almost 894 million BTU. That in part because 88% of Wyoming's electricity is generated from coal.
