The results of experimental and analytical studies of the technological characteristics of a drum mixer for particulate solids equipped with a device for control of segregated flows of non-uniform particles is described. Analysis of the smoothing ability of the mixer was conducted in the course of continuous mixing with micro-dosed portions of one of the components. It was found that under the action of counter pulses applied to the segregated flow enriched with portions of the dosed component there is a sharp increase in the selective smoothing ability of the mixer with respect to this component of the mixture. The effect of smoothing by selective action of counter pulses on the segregated process flow is many times greater than a similar effect achieved by traditional methods such as the intensification of longitudinal mixing and increase in the working volume of the mixer.
