1. Principles of milling bulk solids. Milling is the action of reducing the size of particles thanks to a mechanical action. The mechanical action is submitting the particles to a stress, under the stress, some cracks will appear and subsequently the particle will be broken in different parts.
The quantities of the balls and starting material determine the extent of fill of the vessel and the intensity of the milling process. Typically, the vessel is filled by the balls and starting material to 50% and 25% of the total volume of the vessel, respectively, although variations exist in the literature.
