The article is devoted to mechanising composting based on energy-saving technical systems. The goal of the research is to determine the patterns that describe the impact of different drum-blade working bodies' design and technological parameters on their work energy performance, the homogeneity of the mixture components distribution and their structure in the formed composting pad of a certain height. The physical-mathematical model of the mechanized composting process of organic raw materials from agroecosystems by technical equipment with drum-blade working bodies has been theoretically substantiated and experimentally investigated. There has been developed the mathematical model that correlates the value of the mixing quality variation coefficient with the load factor and the kinematic indicator of the operating mode. It has been established that, if provided the composting pad layer height is the same, the use of a double-drum working body is more rational in terms of power loss in comparison with a single-drum one.
