Ball mills with a drum length to diameter ratio greater than are referred to as tube mills. Ball mills may be primary or secondary grinders. Primary grinders are fed from crushers such as a jaw crusher. Secondary grinders are fed from other grinders a rod mill. Ball mills are usually either of the grate (diaphragm) or overflow type.
