Coal mills are of differing types. The three main types in use today are ball mills, bowl mills, and hammer mills. A ball mill consists of a rotating cylinder or tube containing steel balls. Coal is introduced into the tube and the tumbling steel balls crush it to powder. A bowl mill uses heavy rollers which run against a steel ring or bowl.
