    According to commonly accepted milling guidelines, mill jars of this size should be turning at about80-90 RPMfor optimum milling efficiency. I won't bore you with mathematical details, but the simple way to accomplish an increase of jar speed from 60 RPM to that optimal speed is to increase the drive roller's diameter from its current 1/2-inch diameter up to 3/4-inch diameter.

    Effect ofballsize and powder loading on themilling

    Dec 01, 2013· As the rotation speed (rpm) increases, kinetic energy of the balls increases, which, in turn, shifts the optimumballsize toward a smaller value because the negative influence is alleviated. As the powder loading increases from 1 to 35 g at a given rotation speed (rpm) andballsize, themilling efficiencydecreases monotonically.
