Improving the energy efficiency and wear resistance of mixing devices is one of the priority challenges in geological, chemical, and processing industries. Under conditions of intensive abrasive action of mineral suspension particles on the working elements, a rapid decrease in performance and service life is observed. The nonuniform distribution of velocity and pressure within the flow leads to increased energy consumption and premature blade wear, making the optimization of impeller geometry and operating parameters highly relevant. Addressing this problem contributes to process stability and reduces operational costs. This study presents the results of numerical modeling and tribological analysis of an energyefficient three-blade mixer designed for liquid–solid systems. Modeling was carried out using the finite element method (APM FEM) and hydrodynamic analysis in the KOMPAS-3D environment with the APM Flow module, followed by tribological simulation in MSC Marc. The integrated use of these tools provided a reliable representation of the velocity and pressure fields, as well as the distribution of local contact stresses on the blade surfaces. It was found that an impeller with a 45° blade inclination generates a stable axial flow that prevents solid particle sedimentation and ensures homogeneous suspension mixing. The proposed modeling approach enables a comprehensive evaluation of tribological characteristics, improves calculation accuracy, and supports optimization of energy-efficient impeller design. The results can be used in developing resource- and energy-saving systems for geological and metalworking industries.
