involve grinding). With Lloyd's ball milling book having sold over 2000 copies, there are probably over 1000 home built ball mills operating in just America alone. This article borrows from Lloyd's research, which was obtained from the commercial ball milling industry, and explains some of the key design criteria for making your own ball mill.

The ball mill is a common piece of equipment in grinding circuits. Modeling the grinding process in a ball mill is a complex task. Balls and individual parti cles of varying sizes and geometries collide at various angles and magnitudes. The process is further complicated by the production of countless offspring particles. To simplify the

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.
