Chromite sand was used as the feed. A factorial design was prepared with the following parameters, which influence grinding in a stirred ball mill: pulp density, pin-tip velocity, ball density, and size. The energy required for grinding the chromite sand in the stirred ball mill was determined by the use of Charles' Equation.
