Jul 05, 2020 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.Controlling the particle size distribution at the ball mill will improve the operation and stability of the flotation cells so that chemical costs can be reduced. In addition, the mine operator can specify the coarse material content to meet tailings dam structural requirements.
