The pneumatic system with a vertical annular aspiration channel for vibration-centered grain separators been developed. The rational values of the disk grain distributor are the length of the sectors 0.15 m, the angle of inclination of the sectors 60°. The rotation speed of the distributor in the seed mode (grain supply 5…15 t/h) should be 100…200 min-1 and in the food mode (grain supply 15…25 t/h) must be 100…150 min-1. The effect of the release of light impurities in the developed aspiration system decreases from 45% to 20% with an increase in the supply of grain G from 5 to 25 t/h, herewith at the same time the loss of a full-fledged grain to waste decreases from 0.6...0.8% to 0.3...0.4%, while the effect of the release of light impurities in the aspiration system of the mass-produced vibration centrifugal grain separator decreases from 11% to 4% with the same losses of grain to waste.
