The method according to the invention for operating a classifier for classifying piece-form material has the following method steps: a rotary cage is rotated, classifying air is taken, through an air-routing system enclosing the rotary cage, into a classifying zone formed between the rotary cage and air-routing system, and the piece-form material is supplied into the classifying zone, wherein one or more inserts are arranged in the classifying zone such that the torque to which the rotary cage is subjected - at the same rotational speed - is increased by at least 20% in relation to a design without any inserts and/or the distance between the air-routing system and the rotary cage is selected such that the torque to which the rotary cage is subjected - at the same rotational speed - is increased by at least 20% in relation to a design in which the air-routing system is at a distance which does not affect the torque of the rotary cage. |
