· Ball mills are used by painters, ceramicists and pyrotechnics experts to mix and refine pigments, clay compounds and explosives for fireworks. Load your milling media into your milling chamber. Depending on your mill's capacity, and the material you wish to mill, you can add less or more media, but generally do not load the chamber more than twothirds of the way full.
· 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 single angle milling cutter is used for angular surfaces, such as chamfers, serration's, and grooves. Milling dovetails (Figure 828) is a typical example of angular milling. Milling Dovetails . When milling dovetails, the usual angle of the cutter is 45°, 50°, 55°, or 60° based on common dovetail designs.

Miscellaneous milling equipment. The range of milling equipment is very wide. It includes ball mills, in which the material to be ground is enclosed in a horizontal cylinder or a cone and tumbled with a large number of steel balls, natural pebbles or artificial stones, which crush and break the material.
Ball mill. A typical type of fine grinder is the ball slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
