Kupchuk Igor – candidate of technical sciences (Ph.D in Engeneering), senior lecturer  of the «Department of General Technical Disciplines and Occupational Safety» of Vinnitsa National Agrarian University (Sonyachna St., 3, Vinnitsa, Ukraine, 21008, e-mail: kupchuk.igor@i.ua).

Annotation

Feed make up a large part of the cost for livestock production and determine its quality. A very important technological operation with high energy costs is the grinding of feed grain (wheat, barley, peas, corn, etc.). Therefore, research on the development of effective technologies and cost-effective equipment for grinding is relevant and of practical value.
In the laboratory of the theory of mechanisms and machines of the department of general technical disciplines and labor protection of Vinnitsa National Agrarian University, a vibratory disk crusher was designed to increase the level of technical support for the livestock industry. The crusher uses a more efficient method of grinding feed grain - a combination of impact and cutting, in contrast to a hammer mill that grinds with a free impact of hammers.
The research results of grinding corn grain into feed by a vibratory disk crusher are presented in the article. An experimental prototype of the developed machine was used as an object of research. To register the input and output parameters of grinding, we used the material and technical base of the department of technological processes and equipment of processing and food industries. In order to comply with the zootechnical requirements for the degree of grinding of grain into feed, the dispersion of the obtained product was also controlled. The sizes of the fractions were determined by mechanical separation on a sieve analyzer. Data processing was carried out in the Microsoft Excel software package.
Thus, graphs were obtained and rational parameters of the vibratory disk crusher were determined. This was done by analyzing the performance for the crusher depending on the rotor angular velocity, the sieve perforation diameter and the grain moisture content.

Keywords: feed grain, grinding, vibration, productivity, angular velocity, moisture content.

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.
