Existing calculation formulas for determining the mixer performance do not sufficiently take into account peculiarities of design and shape of mixing chamber. The aim of the study is to determine the performance of a continuous mixer with an energy-saving mixing chamber in the form of a trihedral box. The analysis of factors affecting the mixer performance and the existing calculation formulas for its determination is carried out. It is established that the influence of the mixer working chamber shape on quality and productivity is insufficiently studied, and the influence over the screw space on the filling factor is not taken into account when determining the productivity of continuous mixers. Analytical dependence for determining the productivity of a continuous mixer with a mixing chamber in the form of a trihedral box depending on its parameters and mode, as well as design features, is obtained. By results of researches it is established that, at speed of rotation of the screw 36,61 s-1 and a factor of filling of the mixing chamber 0,02-0,09 productivity of the mixer makes: at mixing of green weight and silage with mixed fodder - 19 t/h, the crushed fodder root crops with mixed fodder - 23 t/h.
