CLASSIFIER AND METHOD FOR OPERATING A CLASSIFIER

Disclosed herein, a classifier for classifying granular feedstock has a rotary cage rotating about a rotor axis and an air-guiding system arranged around the rotary cage, wherein a classifying zone is formed between the rotary cage and the air-guiding system. In the classifying zone one or more baff...

Beschreibung
Zusammenfassung:	Disclosed herein, a classifier for classifying granular feedstock has a rotary cage rotating about a rotor axis and an air-guiding system arranged around the rotary cage, wherein a classifying zone is formed between the rotary cage and the air-guiding system. In the classifying zone one or more baffles are arranged such that the torque acting on the rotary cage is increased-for the same rotational speed-by at least 20% with respect to an embodiment without baffles and/or the separation between the air-guiding system and the rotary cage is chosen such that the torque acting on the rotary cage is increased-for the same rotational speed-by at least 20% with respect to an embodiment wherein the separation of the air-guiding system is without influence on the torque of the rotary cage.
