Abstract.

Principal possibility of obtaining the highest concentration of structured suspension through formation of two predominant particle sizes in the granulometric composition was proved. It is shown that at concentrations typical for the structured suspensions, it is possible to place smaller particles in the space between larger ones, thereby ensuring high concentration and sedimentation stability. It is determined that parameter, which characterizes bimodality of the granulometric composition of the solid phase, is determined by difference between porosity of the particle layer with the maximum advantageous size and porosity of the entire solid phase of the suspension. Dependence of the parameter, which characterizes bimodality of the granulometric composition of the solid phase, on the concentration of particles with the maximum predominant size at different concentrations of the suspension is described. Methods were developed for determining the required volume fractions of each mode of particles depending on the concentration of the suspension and their geometric dimensions.

Keywords: bimodal granulometric composition, structured suspension, solid phase, highest concentration.
