Abstract (en)
[origin: DE4005031C1] The dynamic wind sifter rotor has vertical slats with downstream gas and fines outlets, and coarse particle return. A central riser (1), restricted w.r.t. the mill housing (31) for the air-material mixt. flow is deflected radially outwards at the top of the sifter rotor (5) region, into a gravity flow. Louvres (4) in the sifting chamber (12) point towards the rotor and the flow of air and fines entering the rotor is diverted downwards through the rotor bottom hole (24) round the riser to a down shaft (27) round the riser. Coarse material (42) is returned downwards from the sifter chamber to the housing (31) through lines (32) separate from the riser.
