The issues of numerical modeling of hydrodynamic resistance of the impeller for mixing slurry mixtures in the production of cement compositions are considered. Mathematical models based on the finite element method to analyze the hydrodynamic processes occurring in the mixing of cement-containing mixtures are developed. The influence of rotor design on the value of torque power on the impeller shaft has been investigated. It is established that the most acceptable option is a vane design that creates a good turbulence of the fluid medium in almost the entire volume of the process equipment, contributing to high-quality hydration of cement composites. Optimized power of the drive by the criterion of hydraulic resistance and the number of revolutions of the impeller.
Key words: slurry pool / impeller / hydrodynamic calculation / finite element method / drive power
