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.

Oct 15, 2009 Here's a bucket of crushed powder that I produced by running circuit boards through a ball mill and sieving it. The leftover small pieces of board that don't crush, but were worn 'clean', get leached in a separate bucket. You can clearly see metallics in …

Sep 09, 2016 The grinding media for a ball mill is usually steel balls sized from about 1 to 10 cm in diameter, and for rod mills about 1 to 10 cm in diameter, with the length being slightly shorter than the length of the rod mill. The grinding circuit product can be made very fine, if necessary, with the majority of material finer than 20 microns (um). Lab ...
