How to Make a Ball Mill: 12 Steps (with Pictures) - wikiHow

Aug 10, 2020  Ball mills are a special instrument used to break up hard solids into a fine powder. They are similar to rock tumblers in that the instrument is a rotating container filled with heavy balls to grind the substance into powder. Ceramic material, crystalline compounds, and even some metals can be ground up using a ball mill.
