The processes involved in ball milling are fundamentally different from the solvent evaporation techniques (spray drying and film casting), which is likely to account for some of the differences observed in the solubility curves and the (lack of) fit to the Flory–Huggins model. In the solvent evaporation methods the amorphous dispersion is formed almost instantly from a highly disordered state (“bottom‐up” method),
