Continuous Mixing of Granular Materials under Pulse Action on a Segregated Flow of an Intermittently Dosed Component

Abstract

A controlled segregated process flows principle was used to design a process of continuous mixing of granular materials with intermittent dosing of a microcomponent. Technology opportunities of mixing under reverse-pulse action on a segregated flow of a component in a drum mixer were analyzed. It was determined by experimental and analytical investigation of the mixing dynamics that the selective action of a sequence of reverse pulses on the segregated flow of the microcomponent ensures the production of a mixture the variation of the composition of which is many times smaller than a mixture in a mixer of a flow pattern that corresponds to perfect mixing.
