Ball Mill: Operating principles, components, Uses, Advantages and

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 ...

An Analysis on the Development of Ball Mill - Hxjq Mining ...

Although ball mill has basically completed its localization, the research and analysis on the ball mill has been staying on traditional level.
