Abstract

A magnetic separator for the dry separation of material particles having different magnetic susceptibilities includes a rotatable cylinder that has a stationary magnetic device arranged therein, and extending essentially across its length. A sorting chamber is furthermore provided for which extends along at least a portion of the outer surface of the cylinder in the circumferential direction of the cylinder and parallel to the longitudinal axis of the cylinder. The magnetic separator includes means for the dispersed output of material particles into the sorting chamber, as well as means for generating a stream of conveying air in the sorting chamber. A motor for rotating the cylinder around its longitudinal axis is included, wherein, during operation, the outer surface of the cylinder is moved by the rotation of the cylinder in a direction essentially perpendicular to the direction of the stream of conveying air.
