1 Gather the necessary materials. Making a ball mill is a relatively simple process, but there are quite a few materials needed. A lot of the supplies can be recycled from other projects and found in junk piles, but some may need to be purchased. Once you have the following materials, you can start building (1 in = cm): [2] Wood screws

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 ...
