  • 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 The large balls tend to break down the coarse
