If one mills a white powder like potassium nitrate with lead media, the powder will come out of the mill gray. That means there is some lead in the chemical, which will be in the smoke that results from it being burned. That presents a danger of lead poisoning if one breathes a lot of that smoke.

Highenergy ball milling is an important technology for the preparation of advanced powder materials . As a powder is ground during ball milling, the specific surface area of the powder increases, and a large number of crystal defects are generated. Therefore, the reactivity of the powder is enhanced after ball milling .

Ball mill is typically used to grind and/or blend materials and it can be done wet or dry. It can be used to mix ceramic powders, disperse particles in solvents, homogenize ceramic slurries, etc. Ball mills operate by rotating plastic jars around a horizontal axis, partially filled with the material to be ground plus the grinding medium.

Ballmilling has been recognized as a simple and efficient method to refine original powders. However, an inappropriate ballmilling process might destruct the original particles [12] since the increasing temperature resulted from the violent collosion among milling balls [13] would leads to agglomeration and segregation [12], [14].

We routinely recommend two ways: coffee milling and ball milling. Both ways have advantages. To grind a single chemical (vs. a mix like black powder) using a ball mill, fill your mill jar half full of hardened lead or brass grinding media, and 25% full of potassium nitrate. Turn the mill on and come back in an hour.

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 ...
