CA 2130376
Pneumatic sifter having a device (50) for supplying sift material, where appropriate in common with sifting air, to a rotationally symmetrical sifting chamber (100) enclosing a centrally disposed air-outflow chamber, and having a coarse-grain drain (60). In order, inter alia, to keep the flow resistances low as the air enters into the air-outflow chamber (200), it is envisaged that in the air-outflow chamber (40), along its radial, outer limit, there are disposed at uniform reciprocal angular intervals guide vanes reaching into the air-outflow chamber (40), these guide vanes (30) reaching roughly over the axial extent of the sifting chamber (100).
