A mathematical model has been developed for modeling the technology of shock-impulse molding of concrete mixtures, according to the results of a computational experiment on which rational parameters of the rotor of the throwing device are determined in the form of two rotating cylinders with plates along their generatrices, intended for throwing the components of the concrete mixture onto the molded surface mechanically. A mathematical description of operation of such a device, interaction of individual particles with blades and their flight in the inter-rotor space up to the molding of the manufactured product is given. To stabilize the initial fractional composition of the aggregates, designs of rotors are proposed that provide portion capture of the concrete mixture or the use of the rubberized surface of rotors in the form of elastic tubular elements.
