The classification processes (separation, sorting, separation, fractionation) of dry dispersed materials are quite common in the food, chemical and processing industries, in agriculture, metallurgy, at machine-building enterprises and in construction. In particular, at food enterprises, two groups of these processes are implemented - for the extraction of fractions with particles of various sizes, shapes, densities, aerodynamic or electromagnetic properties from raw materials, or for cleaning the raw materials from impurities (sand, stones, metal particles). At the moment, a large number of methods and methods of classification (mechanical, hydraulic, pneumatic, electrophysical) and types of equipment for their implementation (screens, screeners, triers, drum screens, hydraulic, pneumatic and electromagnetic separators) are known, in this regard, an urgent task is to choose for a specific type of raw material and technology, of the most rational method of classification and equipment for its implementation. The article presents equations and dependencies for determining the time and energy consumption in the implementation of the processes of mechanical classification of grain raw materials using various load schemes using the most common equipment. At the same time, the classification processes carried out under the influence of gravitational or centrifugal forces, vibration effects, and the load created by a hydraulic impulse or electromagnetic drive are compared. As the main operating parameters of the processes, the maximum speed of movement of a particle of the processed material and the energy intensity of the classification were selected. A computer program can be created with using of the proposed dependencies, to develop a rational classification technology, taking into account the physical and mechanical characteristics of the processed raw materials and specific production conditions.

Leading experts in this field, noting the significant contribution to the school of Vibration Engineering under the leadership of P. S. Bernyk, proposed to create a professional all-Ukrainian scientific and technical journal "Vibration in engineering and technology..The journal was foundedat Vinnytsia State Agricultural Institute and P.S. Bernyk was elected to be the chief editor .
For all these years (since 1994) theJournal "vibration in engineering and technology" published 119 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
