Abstract
A device for separating a metalliferous, lumpy mixture, with a conveyor belt and with a rotating drum in which a fixed magnet system with at least one magnet line is arranged. The separating effect of the device is improved and its complexity is reduced where it is provided that the magnets of the at least one magnet line are arranged such that their poles have the sequence NS SN or SN NS in the circumferential direction, as a result of which the ratio of the maximum radial magnetic flux density to the maximum tangential magnetic flux density on the belt surface, facing the material, in the region of the magnet system is greater than one and, owing to this, the electrically conductive particles are separated out into the first partial stream by radial force action (repulsion).

A device for separating a metalliferous mixture of materials, comprising:
- a conveyor belt configured to convey the mixture of materials;
- a rotating drum supporting the conveyor belt;
- a fixed magnet system arranged in the drum, where the magnet system includes at least one magnet line in which magnets are arranged so that their poles have a sequence NS SN or a sequence SN NS in a direction that is circumferential relative to the drum, with a result that a ratio of the maximum radial magnetic flux density to a maximum tangential magnetic flux density on a surface of the belt facing the materials in a region of the magnet system is greater than one;
- such that non-ferrous metals in the mixture of materials are separated by a splitter into a partial stream by force action, due to a formation of eddy currents in electrically conductive particles in the mixture of materials.
