The features of the use of grinding units producedby the SPA “Center” and possible approaches to their calculation are analyzed. The mathematical description of the motion of individual particles of the crushed material in the rotor accelerator of the centrifugal impact crusher is developed. The mathematical model of particle motion along a curved blade on a rotating flat disc, which allows to determine the trajectory of the particles, the magnitude and direction of the full speed at any point on the blade is presented. A graph of full speed and the relative velocity of the particles along the blade, as well as the separation angle, which determines the direction of full speed, the angular speed ofthe rotor are obtained. The change of the complete particle velocity depending on the position of the rotor is analyzed. It is shown that to change effectively the direction of emission of particles from the rotor can be possible only changing its design parameters and parameters of the crusher.
