The article deals with the theory of the movement of material in the vibrating conveyor of a drying installation developed at the National Technical University Dnipro Polytechnic, whose working surface has a stepped shape and the flow of coolant is directed at an angle to the horizontal plane. This constructive solution implements a method of creating a vibrating fluid layer in the working chamber, which significantly increases the drying speed of finely dispersed material. The working surface of the vibratory conveyor is made in the form of a step-shaped grid. Under the action of directional vibration excitation, the material entering drying moves along the grating surface and is blown through the slits with hot air. A feature of the vibro conveyor is the ability to move material with a wide granulometric composition, which includes fractions of grains from micrometers to tens of millimeters. When considering the movement of material along the working surface of the vibratory conveyor, it is possible to distinguish the loading zone and the transportation zone. In the loading area, the material is accepted into transport condition. In the transport zone, the material is subjected to an additional force from the coolant. For the efficient operation of the vibratory conveyor, the speed of movement of the material in the loading and transportation zone must be equal, which requires a comprehensive consideration of this issue. The mode with the separation of the material from the working surface of the vibrating conveyor with the assumption of the absence of air resistance is considered. Differential equations have been compiled and dependencies have been obtained that establish the relationship between the movement parameters of the material in the loading area of the vibrating conveyor, where there is no coolant flow, the angle of inclination of the working surface, width and angle of inclination of the plates forming the surface of the gas distribution grid.

The conditions under which the contact of the material particles with the coolant flow is determined. Differential equations of particle motion taking into account the influence of the air flow on it are obtained, and dependences are obtained that determine the height of the gas distribution grid stage, the angle of inclination of the coolant flow to the horizontal plane, the motion parameters of the material particle with the additional effect of the heat carrier pressure on it.

Thus, the proposed method of calculation allows obtaining initial data for designing the loading section of the transporting surface and the first stage of the gas distribution grid of the vibrating conveyor of the drying unit, as well as analyzing the influence of design parameters on the movement of a material particle.

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.
