how can be measured the diameter of ball mill

  • 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 30 -50 of the mill volume and its size depends on the feed and mill size.
