Making Black Powder with a Ball Mill Skylighter, Inc.
We routinely recommend two ways: coffee milling and ball milling. Both ways have advantages. To grind a single chemical (vs. a mix like black powder) using a ball mill, fill your mill jar half full of hardened lead or brass grinding media, and 25% full of potassium nitrate. Turn the mill on and come back in an hour.Posted 28 August 2009 12:26 PM. Check the other "Ball Mill Media" threads here. Pure lead is too soft, and you'll get significant wear (and contamination of your BP with Lead). Use an alloy of lead that contains Antimony (preferred) or Tin. I'm pretty sure fishing weights are almost pure Lead.Fishing weights as ball mill media Safety APC Forum

My lead ball mill is breeding BB's Tools and Tooling
It's hard to tell if it's from the wood itself (lead shot embedded) or breaking off and rounding of my media. As a control, you could try milling just potassium nitrate or something to see if it's still happening. You may want to try to keep an eye on the mill to prevent it from running without any powder in there.Since you're a mod of this sub. Almighty. I will not recommend glass marbles. However, i will not recommend lead media either. In case you didn't see my edit, lead is extremely toxic and wears down fast, if not faster than glass media.

I think if you talk to the guys manufacturing commercial amounts of 1/2" media you'll find they use 50/50 lead to linotype which would produce lead with 6% antimony which is hard enough. I used 100% linotype (12% antimony) when I made my media and its very hard and puts a lot of undue stress on your mold and is miserable to Subject: Ball milling Black Powder with ceramic media: Bimseby.

Page 3 of 3 Ball mill media posted in Tools and Tooling: The smaller media mills more efficiently (when each ball is heavy-enough to give the desired impacts), not because of the smaller space, but because there are more contact-points in a mass of small balls than in a mass of large ones.

Union Process is the one source for 90%, 94%, 99.5% and 99.9% alumina media. 90% alumina is available in satellites and rod/cylinders. 94% alumina balls have excellent wear resistance with higher impact strength to save running costs with less contamination.
