Study of the mixing processes in a hydromixer with a new working body for production of the high-quality masonry mortars

The importance of preparing the high-quality building mortars used in building houses, all types of finishing the buildings, structures, etc. is increasing currently. The mortars quality depends on plasticity and water-holding capacity (at least 90%); therefore, it is necessary to create conditions for ensuring the required properties in their production. The paper presents results of design, development and study of a new working body in assembly with the destructive partitions. The digital models are constructed for the hydrodynamic simulation and static analysis of displacements and stresses by the finite element method using the CAD/CAE systems. Models of the hydraulic mixer elements are obtained at changing the loading factors, working body rotation frequency, with and without using the destructive partitions. The paper recommends for the masonry mortars to use a Г-shaped partition with the loading factor of 0.7 and the working body rotation frequency of 300 min^–1. An increase in their values would lead to the unreasonable energy costs with the same mixing time and productivity. The partition makes it possible to establish the mixture regulated circulation flows in the working body rotation area and the material vortex flows above the loading level. The obtained results of simulating the hydromixer could be used in various industry areas.
