If you have never seen a ball mill full of black powder or whistle mix explode, you have missed one of life's truly sobering experiences. If you are milling an explosive mix, use lead or brass media. If you are milling a single chemical (not a mix) that is not likely to explode or ignite, you can use ceramic. I'll look around for brass.

Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by ...

Section snippets Experimental. Mechanical milling was performed by using a planetary ball mill (PBM) under various experimental conditions. Copper powder (% purity, median particle size x 50 = 45 μm, Aldrich chemistry) was used as shown in Fig. 1. Mechanical alloying (MA) was carried out at two types of rotation speeds: low (10, 50, and 100 rpm) and high (300, 500, and 700 rpm).

The hardness and yield strength of powder particles were improved by ball milling, so the relative density of milled powder compact was lower than nonmilled compact. Therefore, the sintering density of milled samples is lower. The density of nonmilled and milled samples is ± and ± % after extrusion.

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.
