Abstract

The mathematical description of the motion of particles of grain mixture in the chamber, air separator gravity under the action of a pulsating flow of air of variable speed. An trajectory of particles of different sizes. The resulting equations of motion of particles under the action of a pulsating flow of air to determine the dependence of the velocity of material in grain liquefied air layer of material on a number of factors: the geometric parameters of sieve openings, the angle of presentation, initial the kinematic mode material index kinematic mode sieves and sails share ratio. Theoretically reasonable technological possibilities of the proposed method of separation of grain by the action of air flow and impact on established technological performance parameters: air speed factor with regard to living sectional thickness of material entering the channel.
