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 feed
In discussions on high energy ball milling, the more generic term "ball mills" is often used in place of the terms "stirred ball mills" or "Attritors," but the differences between the types of mills are quite distinct. And, depending on your application, you may find that one type of high energy ball milling is more appropriate for your operation than another. In comparison with conventional

The high reactivity of the powder caused by the high energy ball milling might be reduced by carbon addition. Carbon is successfully introduced into the lattice, as proved by a change in the lattice parameter, a decrease of Tc, an increase of the upper critical field and a change of the Jc dependence on applied field. The carbon substitution in the lattice is accomplished via high energy ball

Planetary ball mills are smaller than common ball mills and mainly used in laboratories for grinding sample material down to very small sizes. A planetary ball mill consists of at least one grinding jar which is arranged eccentrically on a so-called sun wheel. The direction of movement of the sun wheel is opposite to that of the grinding jars (ratio: 1:-2 or 1:-1 or else). The grinding balls
