Based on the known assumption about the predominant effect of dynamic velocity on the detachment of solid-phase particles from a bottom, the suspending condition for a smooth-wall mixer is proposed. The importance of experimental dynamic-velocity measurements for a certain industrial suspension is emphasized. It is shown that the intensive tangential flow of a mixed suspension should be taken into account when calculating the dynamic velocity. The equation for calculating the minimum stirrer rotation speed to exclude the formation of a sediment on the bottom of a mixer is proposed. The equation is experimentally verified for mixers of laboratory and industrial scales in the mixing of L : S systems.
