Abstract
AbstractCompulsory mixers have a fairly high performance, the ability to work both in continuous and batch modes, and are easy to maintain. Twin-shaft paddle mixers with horizontal shafts are used to obtain concretes, putties, dry building mixtures. To increase the efficiency of the mixing process of components, a design of a paddle mixer with rod elements remotely installed in front of the working surfaces of the paddles is distance. The research objective of the study was to evaluate the effectiveness of the proposed mixer design for the preparation of dry mixtures. The problems of carrying out in a well-known software product intended for scientific and industrial modeling, simulation of the mixing process of a two-component material on models of paddle mixers with and without rod elements have been solved; research of mixing processes based on the coefficient of heterogeneity of the mixture widely used for these purposes; comparison of mixing processes of components in the considered models of mixers. In the course of the work, the method of simulation was used. As a result of the study, heterogeneity coefficient of the prepared mixtures and the time of their preparation on the considered models of mixers, the efficiency of using the design of the mixer with rod elements were established.KeywordsTwin-shaft paddle mixerRod elementsSimulationProcessHeterogeneity coefficientEfficiency
