Ball Mill Operating principles components Uses
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 3050 of the mill volume and its size depends on the feed and mill size.
