Hi everyone in the forum. Ball mills are often said to run with media like brass, lead or stainless steel balls/rollers. Is there any chance of accident if I use solid glass balls or marbles as media?

glass can chip, same as marbles (last thing you want is to contaminate your chemicals with glass, people tend to use lead because its heavy and non sparking. if its individual chemicals then things like ceramic media is ok. but for bp ect its not worth the risk.

stay safe and have fun

I have brass in mine, and I'm very pleased with it, though I have a friend who uses glass balls, marbles etc and has had no problems for years.

I tried marbles once, I ended up firing them out of my catapult at tin cans ( thats how effective I found them ), I found them to be too light and to make any good powder I'd have to run my mill 5 times longer than I do using lead balls.

Ceramic media is not particularly dangerous, in fact it is a pretty good grinding media. I've made hundreds of pounds of compositions with it without any problems. The surface is hard and it has a good density to grind compositions within 3 hours to airfloat.
