This paper presents a relevant technological solution aimed at extending the service life of the working elements of a centrifugal impact mill used for producing mineral powder for asphalt concrete mixtures. The purpose of the study is to improve the methods and tools for the mathematical and physical modeling of the said equipment's design. The outcome of the research is the production of effective materials for use in the road construction sector. Operating regimes have been identified that reduce wear on the impact elements and accelerator blades of the centrifugal impact mill when processing crushed stone and reclaimed asphalt granulate. The design diagram of the equipment is provided, along with a mathematical description of the processes governing the formation of rarefied and reflected dispersed particle flows. A comparison of experimental results with the calculations based on the mathematical model showed a discrepancy not exceeding 10%. The proposed mill design ensures the production of high-quality construction material for roadworks and enables cost reduction in the receiving of asphalt concrete mixtures.
