Abstract: A magnetic drum separator (2), with a drum (6) rotatable about a rotational axis (4), a magnet arrangement (10) of a plurality of magnets (12) arranged in the interior (8) of the drum (6), a separation zone (18) in the exterior space (14) of the drum (6); a feed material (22) flows through the separation zone (18) and is there separable with the aid of a magnetic field (26) generated by the magnet arrangement (10), into a waste stream (30) and a recyclable material stream (28). A relative position (R) of at least one of the magnets (12) relative to the rotational axis (4) can be varied. A nominal magnitude (S) for a process value (78) on the drum separator (2) that is influenced by the separation behavior (32) is specified. At least one measurement device (74) detects an actual magnitude (I) of the process value (78), and a controller (82), which changes the relative position (R) of the at least one of the magnets (12), whereby the actual magnitude (I) is controlled to approach the nominal magnitude (S).

Abstract: A magnetic separator separates magnetic and/or magnetisable particles from a fluid with a rotatable drum, at least one magnet arrangement arranged in an interior of the drum and a separation zone through which the fluid can be conducted. The separation zone is formed by an interspace between the drum and a fluid conduction arrangement. It is possible to modify at least locally a distance between the drum and the fluid conduction arrangement and/or a width of the separation zone during the operation of the magnetic separator. A measuring apparatus captures at least one fluid parameter of the fluid. The distance and/or the width can be modified dependent on the at least one fluid parameter. A method operates such a magnetic separator.
