With iron balls, the ball mill would turn at an optimum RPM so that the balls would drop and fall down on the material when the balls reached the top apex of the mill. I''ve done quite a bit of ball milling of incinerated jewelers buffing dust and always used steel balls. I would guess that, maybe, the alumina balls might work OK with that, but
