updated fri 12 jan 07 John Connolly on wed 10 jan 07 Donna, I don't know about the use for a ball mill, but back in the 50s, in my first job out of the Air Force, I worked in a small manufacturing plant in Burbank. On of my tasks was to run parts through various abrasives in a stamdard cement mixer.
I've used the harbor freight 3lb ball mill without modification. Not well. Like BatDad said, the 2barrel ones from HF are cheaper and work well for 175g batches/drum. You'll want to slip a piece of vinyl tubing over the drive shaft to increase it's diameter and get the rotations up from 60 rpm default to the ideal 90 rpm for that size (6") jar ...
These tumblers are called "ball mills" because rock is placed in the tumbler with heavy steel balls. When the tumbler barrel turns the balls are lifted up the wall of the barrel until gravity causes them to drop down onto the ore, crushing it into tiny particles. The largest of these tumblers can process hundreds of tons of ore at a time.

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.
A ball mill. Similar in concept to a rock tumbler, but used by industry to powderize or smooth materials. Balls are added to the drums to do the work. The drums are hexagonal to encourage the material to turn over and mix. In a round drum, the material wants to just slide continuously on the bottom unless a paddle is added.
A rock tumbler functions on the same principle. Ball mills are also used in pyrotechnics and the manufacture of black powder, but cannot be used in the preparation of some pyrotechnic mixtures such as flash powder because of their sensitivity to impact.
tumbler (Lortone 3A) to use as a ball mill. After finding this newsgroup and reading quite a few of the postings here I got the idea that that making BP in a rock tumbler was probably not going to work very well, but I decided to give it a try anyway.

I can find rock tumblers up to 12 pounds (content weight) on Most rock tumblers will not turn a load of lead balls simply because a mill jar full is too heavy. Use CERAMIC media. With ceramic media you should be able to load a 12 pound jar with 9 pounds of media and 3 pounds of ingredients and make a batch in 4 hours.
