Annotation

The motion of a screen with a single-acting inertial exciter located in the vertical plane is considered. The working surface has longitudinal circular furrows. Differential equations of the working box motion are composed and the amplitude characteristics are plotted. The analytical dependences that determine the parameters of the particles motion along the working surface length within a single furrow are obtained on their basis. It is shown; that the chaotic motion of the material intensifies and accelerates it’s mixing in the layer, due to the spatial vibrations of the working surface in the transverse direction.

Keywords: screen, vibration, spatial oscillations, circular riffles, material movement

History of journal:

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.
