The coal is ground between the rollers and grinding table. When enough coal has been reduced in size, it will flow over the top of the dam ring ( retention ring ). Coal Pulverizer Inlets and Outlets Louvres ( nozzle ring) around the outer perimeter of the grinding table allow hot gas to flow into the grinding mill through the mill base.
