In recent years, a great deal of interest has been

shown in developing methods for preparing super—clean

coal containing less than 2% ash and 0.5% sulfur. New

techniques for recovering fine coal, such as

micro—bubble flotation, can achieve the desired result

provided mineral matter is sufficiently liberated. To

achieve sufficient liberation, however, it is often

necessary to grind to a mean particle size finer than

10 microns. Since conventional ball mills are highly

inefficient in this fine size range, the stirred ball

mill has been proposed as a more suitable means for

ultrafine grinding.
