Abstract
In a screening device for sorting granular material with at least one rotatable rod basket and a downstream fine material separator a cyclone-type eddy separator is attached with the smaller diameter of its housing cone in order to draw off the screening gas flow charged with fine material and flowing out due to twisting energy in such a way that the rod basket screening device and the separator form a compact unit. A submerged pipe is located in the center of the cyclone-type eddy separator for drawing off the screening gas flow freed of fine material. At least one opening is provided for discharging the fine material at the periphery of the eddy separator housing.
