The results of the experimental studies of dispersion process of solid material in liquid medium using bead milling were presented in this article. The method of the experiment conducting was described. Differential and integral functions of distribution of solid phase particles in the suspensions were used. As a result of the research, the influence of the main technological parameters on the particle size distributions of the obtained suspensions and the specific surface of solid phase was established. The main considered parameters were: the duration of grinding, the consumption of the suspension, the speed of the mill rotor and the addition of a surfactant to the initial suspension. It was established, that the main process occurring in a bead mill is the crushing of large fractions of solid material in the initial suspensions. The process of the multiple grinding was also investigated.
