Analysis and evaluation of structural and technological parameters of forced action mixer was carried out on the basis twin-shaft forced action mixer. Theoretical methods of moving material into the twinshaft mixer chamber, using a stochastic approach were proposed in this article. The process of moving material was researched by the theory of Markov chains. Based on the proposed method of improving system of quality assessment in terms the variation coefficient of mixture. And was predicted that the main parameter that affects the direction of movement particles of material and quality of mixing is the rotation angle of the blade. It was the main option of the research. To test the theoretical foundations of the movement of substances and improve the quality of the mixture, experimental stand was developed – Laboratory twin-shaft forced action mixer with changing angle blades. The conducted experiments have confirmed the validity of theoretical research. The Algorithm of design of new constructions of twins-shaft concrete mixers was proposed, based on conducted researches. The working hypothesis that the movement of material between the mixing zones depends on the "transition probabilities", which is defined by angle blade was confirmed as a result of mathematical modeling of moving material and performed experimental studies. On the basis of theoretical research the method of calculation of basic parameters of advanced laboratory twin-shaft concrete mixers was crated. The laboratory twin-shaft concrete mixers with rotary blades was created. The investigations can improve the efficiency of the mixer by reducing cycle time and energy consumption.
