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 ball mill is a hollow drum closed with loading and unloading end caps, filled with grinding media and rotated around its axis. The drum of the ball mill (Pic. 1) is a hollow cylinder of steel, lined inside with armor lining plates which protect it from impact and friction effects of the balls and the grinding material.

Colloid mill is a machine used in the disintegration of solid particles or droplet size of a liquid present in suspension or emulsion. The machine consists of an inlet (which is subjected to a tremendous shearing action that effects a time dispersion of uniform size) and an outlet. Colloid mill works on the rotor-stator principle.
