Abstract:
1. A device for separating magnetizable particles from a suspension in a material flow and contains metallic and non-metallic fractions and has a predefined mass flow rate, the device comprising: a longitudinally symmetrical magnetic separator comprising a magnetic device for producing magnetic fields for separation of the material flow into multiple constituents, and a separating screen that is at least partially tubular in shape and arranged within the longitudinally symmetrical magnetic separator, the separating screen separating an interior area radially inside the separating screen from an exterior area radially outside the separating screen, the exterior area defining a separating gap between the separating screen and an inner wall of the longitudinally symmetrical magnetic separator, the separating screen being adjustable in a circumferential direction of the longitudinally symmetrical magnetic separator to thereby adjust a gap width of the separating gap, and electronic control elements configured for adjusting the separating screen to thereby adjust the gap width of the separating gap, which electronic control elements receive as a control variable a signal based on a magnetite quantity contained in parts of the material flow or in the material flow relating to the volume-based magnetizability thereof.
