How ball mills work A ball mill grinds material by rotating a cylinder filled with media typically metallic or ceramic balls mixed with a continuous flow of feed and recycled material At slower rotational speeds the grinding media creates a cascade motion where the media is mainly rolling and shear forces for grinding are generated

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis The balls which could be of different diameter occupy 30 50 of the mill volume and its size depends on the feed and mill size

Types of Mill Feed Chute Scoop Feeders for BallRod Mills are made in various radius sizes Standard scoops are made of cast iron and for the 3′ size a 13″ or 19″ feeder is supplied for the 4′ size a 30″ or 36″ for the 5′ a 36″ or 42″ and for the 6′ a 42″ or 48″ feeder
