Theoretically, raising the speed can endlessly increase the kinetic energy per unit volume. When the needed fineness is in the submicron level, stirred ball mills can therefore be filled with microbeads with diameters of 200/m. Tumbling ball mills have a minimum bead diameter of about 1/2", or 13,000/μm.
