1. Mill Volume Analysis. The volume of your ball mill sets the stage for efficient milling. Calculate it by multiplying the total mill volume, accounting for void spaces, by the fraction filled by the balls. Typically, aim for a filling fraction between 30% and 50%. 2. Ball Mass Computation. The mass of the balls is a critical parameter.
