If a ball mill uses little or no water during grinding, it is a ‘dry’ mill. if a ball mill uses water during grinding, it is a ‘wet’ mill. a typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
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.
