Homemade ball mill - Tools and Tooling - Forum

You'd probably want to run at 'optimum speed' for dry powders, which is about 65% of critical speed. With the diameter of your media (1/2" balls ?) and the INTERIOR diameter of your mill jar, you can calculate the critical speed required, and the by multiplying this by 0.65, you'd arrive at a reasonably optimum speed.
