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.

Rapid mechanochemical synthesis of amorphous alloys: AIP
A method of rapidly making highly amorphous alloys by SPEX milling was developed. It was found that the rate of amorphization and alloy formation increased with lower ball diameter and a larger amount of balls. This is in contrast to the small number of larger balls typically used for SPEX milling.

Production of Gold
The Ball Mill, B-101, grinds the 0.25” ore until it is in the range of 160 microns. The ore leaving the ball mill is sent to six hydrocyclones that separate the larger particles from the smaller particles. The top stream leaving the cyclone is 75% of the feed into it. This top product is 160 microns or less.
