Annotation

The efficiency of grain mixtures separation is to a considerable extent defined by the sieve loading. The presence of overloading and underloading segments leads to the decline of quality and productivity of the separation process.

The article presents the research results of influence of initial mixture serve size on a distribution process of the specific loading on a inclined flat vibrating sieve. For research of process the mathematic models of spatial motion of a loose mixture flow along the inclined vibro-sieve of finite width is used. The boundary conditions on the surfaces which restrict the volume of the loose mixture are made. Influence of sifting of mixture on the process of loading was not taken into account.

Regularities of change of the specific loading on length and width of sieve have been investigated. It have been determined that change of size of the initial specific loading influences substantially on mutual location of overloading and underloading segments of working surface, their area and amount.

 

Keywords: vibrating sieve, serve of friable mixtures, specific loading of surface

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.
