Using a three-factor experimental design on a test bench of a roller screen with a screw intensifier, regression equations were obtained that describe the influence of the kinematic parameters of the device and the supply of gravel to the chute on the efficiency of material separation and the specific productivity of sifting the fine fraction. The graphical dependences of screening efficiency and specific productivity on a roller chute on changes in the rotation speed of shafts with disks and on the screw rotation speed are presented. The influence of changes in the amount of material supply on the specific productivity of a roller screen is considered for the entire range of varying the rotation speed of shafts with disks and the speed of rotation of the screw. For maximum gravel supply, rational operating parameters of the chute shafts and auger intensifier were determined, ensuring high separation rates of the stone material.
