Abstract. The problems associated with the modernization of roller vibrating classifier are far from being solved and require further theoretical and experimental efforts. The studies have been concentrated onthe motion equation of dynamic oscillating system whether the appearance and maintenance of rotational motion takes its place with the simultaneous appearance of vibrational impulses within the construction of executive screening surface. There are periodicity conditions for this vibroimpact mode determined. The implementation of stability conditions of the rotational motion of executive rollers having either four or eight impactors is verified. The obtained results indicate that the forced oscillations inside of the considered dynamical system might be periodic by their nature when the stability conditions are satisfied. These conditions’ satisfaction, beyond any doubt, is a guarantee of enhancing the effectiveness of the roller vibrating classifier.

Keywords:
