13-11-2017· Media or ball milling can be performed in dry or wet conditions, though wet grinding generally results in a finer product due to the reduction in particle strength and the dispersing effect of the liquid medium . Wet media mills are especially useful for the micronization of particles into the submicron range [13, 33, 34].
