Mixing process simulation of the initial building materials components using the DEM Solution EDEM system

Abstract

Abstract Quality of building materials, products and constructions depends on the organization of technological process of their production, and it, as a rule, concerns preparatory operations, such as crushing and in a greater degree mixing of initial compound components of the future products and constructions. Production of high-quality building mixtures is one of the most actual tasks of modern building technologies. Today, the mixing of bulk materials has evolved into a special branch of technological knowledge, which is based on mechanical processes, whose goal is to ensure the highest possible degree of alignment of individual components in the mixture. Due to the development of digital technology, modern industry is able to abandon expensive and long field experiments and tests in favor of digital experiments. The results of digital experiments have a high degree of convergence with real experiments, but are carried out many times faster. To model the influence of the material loading method on the heterogeneity factor of the mixture, digital sampling was carried out using EDEM software in a screw type mixer.
