Only particle below a target size will be allowed to leave the mill, the others will be recirculated. Mills with size reduction media: Ball mills (dry) Ball mills are basically made of a drum partially filled with a grinding media, typically beads of ceramics or steel.

Typically only 7 to 13% of the input energy is utilized for size reduction during ball milling, while the remainning energy dissipates mostly as heat. The energy provided to the milling process is distributed among different subprocesses within a mill,

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.
