Development of domestic scientific research directions in the field of equipment for separation of particulate materials

The article presents a comprehensive analysis of the development of domestic scientific research directions in the field of design and modernization of equipment for grinding and separation of particulate materials over the period 1989–2025. Based on a foresight analysis of doctoral dissertations in the field of mechanical equipment, systems, and technologies, research topics have been clustered, and the dynamics of scientific activity, its geographical distribution, and interdisciplinary connections have been assessed. Key trends have been identified: the predominance of studies focused on centrifugal separators and classifiers (accounting for approximately 40% of all works), a growing interest in mathematical modeling of aerodynamic processes (reaching up to 25% by the 2020s), and optimization of grinding plant operations. Particular emphasis is placed on the role of leading scientific schools and their contributions to advancing calculation methods, structural refinement of equipment, and the development of energy-efficient technologies.
