Abstract: The process of a vibration concrete mixer has been investigated. Well-coordinated equations of motion of the system «mixer – concrete mixture» and their solutions have established the regularities of changing the parameters of the mixer at different angles of inclination. An experimental design of vibration-gravitational mixing has been developed and manufactured, and studies of the working process of mixing efficiency have been carried out on it. Research carried out at three warehouses of concrete mixtures confirmed the assumptions accepted in the work, the assumption and the selected physical and mathematical model of the «Mixer – concrete mixture» system. The use of a vibration concrete mixer made it possible to reduce the duration of mixing by 2.5–3 times in comparison with conventional free mixing concrete mixers. Provides the preparation of hard concrete mixtures and improving the quality of concrete mixtures due to the destruction of defective aggregates and a more uniform distribution of the binder throughout the volume of the mixed mixture. An algorithm and method for calculating the main parameters of a vibration concrete mixer have been developed.
