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.

A good rule of thumb is to fill the container about 1/3 of the way with the balls. 2 Add the chemical you need to grind. You can fill the container with as much of the substance to be ground as you'd like. You simply need to leave enough room for everything to be able to move around. Keeping the container about 2/3 full should be good. [10]

The milling process requires a milling machine, workpiece, fixture, and cutter. The workpiece is a piece of pre-shaped material that is secured to the fixture, which itself is attached to a platform inside the milling machine. The cutter is a cutting tool with sharp teeth that is also secured in the milling machine and rotates at high speeds.
