Ball drum mill. Design, structure diagram, operating ...

The ball drum mills (BDM) are designed for grinding clay slates, anthracites, lignite and black coals. Such mill types are mostly used in thermal electric power plants as they are designed for continuous operation in dust production systems. The coal is ground by impact and abrasion action of the balls charged into the horizontally arranged and bearing-supported drum.
