The article presents the results of the analysis of vibration mixers designs, presents their classification. The classification is based on the principle of action and the method of mixing. Practice has shown that mixing by vibration produces a significant effect. With vibrational mixing, all the expected components are evenly distributed throughout the volume of the mixture. The main disadvantage of the vibration method is the negative impact on the design of the mixer, as well as on the environment and humans.
The problems that complicate the design of vibration mixers include a wide range of physicomechanical properties of the mixed components, a significant difference in the concentration of the components of the mixtures. The advantages are the intensification of the mixing process, the possibility of more efficient mixing of materials with different physicochemical properties compared with other mixing methods, significant time savings on the process, and energy efficiency of vibration technologies. Three main categories of vibration mixers are distinguished by design features and the mixing method: vibration mixers with self-circulation of the mixture, vibration mixers with forced mixing with vibration effects on the components of the mixer, vibration mixers with free mixing with vibration effects on the components of the mixer. Based on the analysis, one can consider a perspective direction the design of vibration mixers of the first and second groups, increasing the efficiency of vibration mixers is possible through the introduction of the latest technologies and the use of modern materials. The creation of effective vibration exciters is one of the main tasks of improving the design of vibration mixers. A comparative analysis of vibration mixers with mechanical inertial, eccentric, electromagnetic, pneumatic, hydraulic and other types of vibration exciter is carried out. One of the promising directions for the design of vibration mixers is associated with the creation of effective vibration exciters with an amplitude controlled during operation.

In June 1994 the 2nd International Scientific and Technical Conference "Application of vibrations for technological purposes" was organized on the basis of Vinnytsia State Agricultural Institute. 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 94 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
Currently Kaletnik H.M PhD , professor, academician NAAS is the chief editor of the "Vibrations in engineering and Technology"
The journal "Vibration in Engineering and technology", which has no analogues on the territory of Ukraine, is well known abroad.
