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.

Ball Milling Theory Introduction: Figure 1: Ball milling terminology. I was first given the formula for gunpowder by my Uncle at age 14, after he had observed my apparent obsession with class C fireworks. Being a scientist who had experimented with the ancient recipe himself during his youth, he thought I should try making my own fireworks.

are present in the ball mill feed and are produced as the particles pass through the mill. For example, when 60% of the solids in a ball mill is coarse, then the coarse solids inventory * in the mill is 60%, and only 60% of the mill grinding volume and power is used for the grinding of coarse particles.

Ball mills are the all-rounders used for the milling and homogenization of a broad range of samples prior to analysis. They are advantageous for bringing samples into a homogenous pulverized state and preparing them perfectly for either additional sample preparation steps like extraction, digestion, and filtration, and/or for subsequent analysis like XRF spectroscopy.
