Grinding differs with the pyroprocessing process (kiln type) used. In dry processing, the materials are ground into a powder that can flow in horizontal ball mills or in vertical roller mills. In a ball mill, steelalloy balls are responsible for decreasing the size of the raw material pieces in a rotating cylinder.
