Annotation

The problems associated with efficient classification of hard-to-sieve wet and sticky mined rock masses are far from being solved and require further theoretical and experimental efforts. It is the purpose of the present investigation to determine the values of impact energy required to destroy the layer of mined rock by the vibrating roller classifier executive tool, which could be implemented either with rubber or steel material. The authors carry out the experiment to compare different material types of the teeth of vibrating roller classifier in order to get the maximum value of impact energy. Experiments involved measurements of height of fall H, thickness of a mined rock layer h with taking into account different sizes and humidity of the rock lumps. As a result of the experiments we can conclude that at sieving wet materials rubber teeth disks show characteristics similar to steel ones, what confirms the efficiency of their use for the classification of hard-to-sieve wet mined rock.

Keywords: rubber, steel, toothed disc, vibrating roller classifier, impact energy, wet and sticky mined rock

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.
