Simulation model for the collision of the individual components of dry mixes with the inner surface housing during their preparation in high-speed twin-rotor turbulent mixer

Abstract

Abstract To mix the components of dry construction mixtures, various mixer designs are used. Forced mixers are considered the most effective. The mixing of the components in the working space of the forced action mixers is carried out due to the repeated action of the working body on them. In the process of multiple interaction of the working body and the particles of the mixture, they are repeatedly moved in the working space of the mixer. The nature of the movement of the particles of the mixture in the working space is chaotic in nature, which makes it impossible to determine the necessary time for preparing a homogeneous mixture. To ensure high uniformity of the prepared mixtures, it is proposed to use the design of a new mixer with a cascade principle of mixing the components of the mixture. To determine the trajectories of the mixture components in the working space of the mixer of a new design, it is proposed to use the results of the presented analytical studies.
