Time optimization of the mixing process of concrete mix components based on unsorted gravel-sand aggregates of the initial rock

The article proposes a new method of control and a system for regulating the uniformity of the concrete mixture in the technological process of mixing components. The theoretical substantiations of the control and regulation of the homogeneity of the mixture associated with a change in the frequency of vibrodynamic vibrations of the mixer body are given. Such technical means as vibroacoustic sensors, communication devices with the object, electropneumatic executive regulating mechanisms are selected. To determine the quality indicator of automatic control in the system, a structural block diagram with transfer functions is proposed that determine the process of operation of the ATS in a transient dynamic mode. The mixing zones of the components that determine the optimization of the uniformity of the concrete mixture in the technological cycle of the mixing process are determined.
