  • 5.2.3 The Ring Rolling Process

    Ring rolling is a hot forming process that produces seamless rings varying in size from a few inches in diameter and weighing less than one pound to over 25 feet in diameter and face heights approaching 10 feet. The process and equipment are similar in principle to rolling mills used for plate. In both processes the metal is rolled between two rolls which move toward each other to form a

    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.
