As the material is ground by the rollers, it continues to move to the periphery of the grinding table. As the material spills over the dam ring, it is suspended in the air stream by the hot gases from the kiln or preheater. The hot gases enter the base of the mill and pass upwards through a louvered annular ring around the grinding table.
