How I built a quick and easy homemade ball mill
It doesn''t look like much, but it works great, and it cost almost nothing to build. As a bonus, this ball mill can also be used as a rock tumbler, or a glass tumbler to make your own quot;sea glassquot; at home. To use the mill as a rock tumbler, just leave out the steel balls, add rocks, tumbling grit and water, and let it spin.
