My very first ball mill such as it was used a few pounds of stainless steel nuts and bolts for the medium charge. Ball bearings are very good for milling. Muzzle loading balls are, also. Fishing weights work (egg weights are about the best). Marbles work. Some people (scaring me as they do it) use glass marbles to mill black powder. LLoyd

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].

There are three factors that set brass milling apart from other manufacturing processes: 1. Clamping. As the router rotates at rpm, tremendous force exerts on the workpiece from the top down and sideways which makes clamping it from the top and sides is essential. The base plate can be made of polycarbonate or metal.
