FIELD: separation of bulk materials, in particular, grain material in grain combines. SUBSTANCE: separator has screens connected in pairs through connecting members, drive for imparting longitudinal oscillations to screens in opposite phase and mechanism for oscillating screens in vertical plane. Apparatus is further provided with mechanism for oscillating screens in transverse direction in horizontal plane. While passing through screens, particles of material effectuate complicated motions. Mechanism is completely self-balanced. EFFECT: increased efficiency in grain separation. |
