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, you'd arrive at a reasonably optimum speed. I should have asked you what size your jar's interior diameter and media size are, in order to give you a more responsive reply.

How do you calculate speed and feed? Speed (RPM) = (Surface Feet per Minute x ) / Diameter of the Tool. Feed Rate = RPM x Chip Load x Number of Teeth. RPM = Of the tool or workpiece. Chip Load = The amount of material removed, per revolution per cutting edge. Number of Teeth = The number of edges, facets, or flutes.
