In the past I also had the same problem with a ball mill as Jack explained. But if I were to apply Mark's collection system to the ball mill it might perform better and could be a scheme used in remote areas of the world. So, for the present, I'm leaning towards a 55 gallon drum ball mill with an air-swept collection system.
Is there a way to calculated the needed (about) cfm of air flow? I'm looking at an industrial shop vac with 175 cfm (5 m^3). Excellent price but it only has a 1.5" hose (3.81 cm).
