<p>A pneumatic sifter includes a feeder for supplying sift material, optionally with sifting air, to a rotationally symmetrical sifting chamber which surrounds a centrally disposed air outlet chamber, and a coarse particle discharge. In order to keep the flow resistance low as air enters into the air outlet chamber, guide vanes are provided in the air outlet chamber, which are spaced from each other at uniform angular distances and extend approximately over the axial extension of the sifting chamber.</p> |
