Characteristics of Continuous Granular Materials Mixer with Pulse Action on Segregated Flow of Batch-Dosed Component

Abstract

A method of smoothing uneven dosing of microcomponents in continuous flows of granular materials by the action of a cascade of counter pulses on a segregated flow of the components is described. Mathematical modeling is used to analyze the physical mechanism of smoothing fluctuations of microcomponent dosage portions in a continuous granular materials mixer having a rotating drum. The influence of design and operating parameters of the apparatus on the magnitude of fluctuation of concentration of batch-dosed components in the mixture is studied using an experimental relationship that determines the intensity of formation of a segregated flow in a drum apparatus for a mixture of model granular materials.
