Summary: Classification processes (separation, division, sorting) take an important place in food industry where they are used, in particular, for selection of some fractions of grain raw materials (wheat, barley, rye, corn, sunflower, groats) by form, sizes, density or aerodynamic properties of particles of the material or for removal from grain of pollution particles (soil, sand, stones, metallic shaving). The separation processes are quite wide spread in other branches of economy (in chemical, processing, machine building, building, agricultural, metallurgy enterprises), so a task of improvement of classification processes and equipment for their realization is enough actual. Different installations for mechanical classification with unbalanced, hydraulic pulse, pneumatic, electromagnetic, centrifugal drive have reliable design, provide quite stable and effective working process. By our notion, the main working parameters of the mechanical classification of grain raw materials, that determine its efficiency (productivity, specific energy outlay, quality of phase separation) are the maximal speed of movement of the material particles relatively sieve surface and a maximal effort created by the executive element of the installation in the middle of the processed material. Known differential equations of movement and energy balances for determination of these working parameters are complex and unsuitable for elaboration of the engineering method of design calculation of corresponding equipment. So, there are algebraic dependencies for definition of the main working parameters of the mechanical classification under using of basic drives types presented in the article. On the basis of these dependencies, a simple computer program can be compiled to obtain and analyze graphic diagrams that allow to determine the most efficient drive option.
