Abstract-Peculiarities of development of gyroscopic-type mixers were considered. The expediency of development of such mixers is presented. The literature review on this subject was performed. Author's kinematic scheme and a variant of the laboratory plant of the mixer (three-dimensional model), describing the influence on the material, mixed in the mixing chamber realtively two inteperpendicular horizontal axes, were presented. The mixing chamber is rotated by means of conic, chain and cylindrical gearings. The emerging complex spacial motion of material particles can be regulated by the frequency transformer and selection of corresponding cogwheels. The part of the methodology on defining the path of material particles in the mixing chamber is presented. The spatial task is solved mathematically. Preliminary experimental studies were conducted. A central composite orthogonal plan of the fractional factor experiment was chosen. Four parameters were chosen as input factors. An example of machine realisation of the task by means of SolidWorks Flow Simulation was presented. Conclusions about the work were made.
