Abstract

The article presents the results of the movement and distribution of gravel grains, depending on their size, along the inclined surface of a trough-shaped roller sieve. The process of screening a fine fraction of gravel along the width of a chute with an auger intensifier has been studied. The parameters of the separating device have been obtained, which ensure the highest efficiency of stone material screening due to the rational distribution of material fractions over the roller sieve.
