involve grinding). With Lloyd's ball milling book having sold over 2000 copies, there are probably over 1000 home built ball mills operating in just America alone. This article borrows from Lloyd's research, which was obtained from the commercial ball milling industry, and explains some of the key design criteria for making your own ball mill.
How I built a quick and easy home-made ball mill. The ball mill is powered by a fairly robust 12V DC motor salvaged from a junked printer. It had a pulley for a fine-toothed belt on it. It was left in place and it seems to drive the heavy round rubber belt well without slipping. The motor .

In theory it would work but I see two problems. First, you would need to gear down the drill quiet a bit because a ball mill works better at a slower RPM. Second, I would be afraid a drill would start to overheat. A ball mill usually runs for hours and sometimes days on end, and drill motors aren't designed for that prolonged of use.
