Abstract. This article presents results of experimental research of dependence of design parameters of the roller vibrating classifier and roller vibroimpact classifier on their productivity. Their productivity is determined depending on their such design parameters as slope angel and gaps between the rollers, on such properties of the mined rock as its moisture content and bulk density, such their operation parameters as angular frequency of the vibration exciter and specific load per area unit of the screening surface. Findings of the experimental research allow to highly estimateadvantages of the roller vibroimpact classifier as its productivity indicators are much better in comparison with the roller vibrating classifier. The analysis findings of this experimental research will be presented in subsequent papers of the authors.

Keywords: experimental studies, flap rollers, smooth rollers, vibroimpact mode, vibrating roller classifier, roller vibroimpact classifier.
