· Purpose: Ball milling is a popular process for obtaining fine powders in the part and material industry. One of important issues in the ball milling is to produce particles with a uniform size. Although many factors affect uniformity of particles, this paper focuses on the choice of ball diameter. Consider a ball milling where balls can be taken with three different diameters.

Moreover, depending on milling conditions, the order-disorder transition is found to be either of first or second order, as predicted by the model. The same approach is shown to rationalise experiments proving the stabilisation by ball milling of immiscible elements into a solid solution at low enough temperature.
