Abstract.

The article presents results of experimental studies on determining forces of the shock interaction between executive tools of the vibrating roller classifier and the mined rocks. Dependence of these forces of the shock interaction between the star screening surface of vibrating roller classifier and lumpy rocks was specified. The forces of the shock interaction were determined depending on such design parameters of the roller stars as elasticity modulus of star rubber material, hardness of rubber material by Shore A scale, estimated length of the star console and number of the star console flaps, and depending on such mode parameters of the classifier as angular frequency of the star rotation. Findings of the experimental research are that, under the impact of certain selected variable parameters, additional star-like forces appear on the screening surface of a vibrating roller classifier which could destroy internal bonds inside a sticky rock mass. Analysis of the experimental results will be presented in the author’s subsequent publications.

Keywords:

forces of the shock interaction, star screening surface, vibroimpact mode, vibrating roller classifier, impactors.
