Abstract
The device for separating and screening bulk materials, in particular crop materials, is formed by a zig-zag separator (9) with separation conduits (14) which are diverted once or several times in the vertical direction and through which a separator air stream (SL) flows, and its top and bottom which is covered by the bulk material (6, 7)--crop material--forms a screening surface (9a). The zig-zag separator (9) forms a cross flow orientation of the rising separator air flow (SL) at the bends (14a) of its separator conduits (14) and a rotating material vortex (GW) in the separator conduits (14), by means of which the light chaff/stalk parts (7) are moved upward and the grain (6) is released downward.
