The article presents the results of studies of a new design of a two-shaft centrifugal vibration module, which was created on the basis of the modernization of a two-shaft disintegrator. A distinctive feature of this design is the presence of an additional device that provides the operation of vibrational classification by size of the crushed rock mass directly in the grinding chamber. This eliminates its regrinding and increases the performance of the module. 

Since structural changes were introduced into the previously existing disintegrator design and new technological operations were added, a set of studies was carried out to determine the performance and expended drive power of the module, depending on the most influential operating parameters and rock mass characteristics. The main variable parameters were adopted: the number of revolutions of the beater shaft in the grinding chamber, the frequency and amplitude of oscillations of the grinding chamber, the size and strength of the crushed rock mass, and the effect of the screening process of the finished size class in the grinding chamber on the productivity and power consumption of the drive was established.

It has been established that the efficiency of rock mass screening in a centrifugal vibration module is within 60 ÷ 70% depending on the separation size class and the density of the processed rock mass, as well as on the content of the finished size class in its loading. In this case, the performance of the module increases by 20%, and with the use of vibration excitation of the grinding chamber - by 25 ÷ 30%. 

The obtained experimental dependences of these values on variable parameters are presented in the form of graphs with their further identification by regression models, which will allow us to determine its main structural and power parameters when designing the parametric series of the module (based on the initial requirements). 

The results of studies of the experimental model of the module showed the effectiveness of the modernization and allow us to recommend it for wide industrial use.


Keywords: module, rock mass, shock, vibration, classification, productivity, capacity.

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.
