The article presents the results of the influence of technological factors on the efficiency and time of the gravel screening process on the roller grooved sorting with an auger intensifier. The article obtains the dependences of the efficiency of the gravel separation on the material feed to the sieve, the rotation direction of the auger, the rate of the gravel feed and the composition of the original mixture. The article reasons the technological parameters of the grooved screen, providing the highest rates of fractionating stone materials. The expediency of the selected technological characteristics is proved. It is based on the example of the obtained dependences of the efficiency and specific productivity of the screening process on the rate of the material feed with the most rational structural and kinematic parameters of the grooved sorting with an auger intensifier. Keywords—grooved roller sorting; auger intensifier; material feed; the direction of the material transportation, the efficiency and time of the screening; gravel.
