Abstract
The invention relates to a method for separating feed material, wherein the feed material comprises at least one ferromagnetic material fraction and a non-ferrous material fraction, wherein a conveying stream is fed to a first separation of a first ferromagnetic material fraction, in particular by means of a first magnetic separating device (1), wherein the conveying stream is subsequently fed to a second separation of a second ferromagnetic material fraction from the conveying stream, in particular by means of a second magnetic separating device (2), and wherein a redistribution and/or reallocation of the material of the conveying stream takes place between the first separation and the second separation.
Claims24
A method for separating feed material, wherein the feed material comprises at least one ferromagnetic material fraction and one non-ferrous material fraction, the method comprising:
- feeding, by a first magnetic separating device, a conveying stream to a first separation of a first ferromagnetic material fraction, and
- feeding, by a second magnetic separating device, the conveying stream to a second separation of a second ferromagnetic material fraction from the conveying stream,
- wherein a redistribution and/or reallocation of the material of the conveying stream takes place between the first separation and the second separation, and wherein the second magnetic separating device is at least in part arranged below a further conveying device, facing away from the first magnetic separating device, and the second magnetic separating device is a rotatable magnetic drum, and
- separating, by an eddy current separating device and after the second separation, at least one non-magnetic and electrically conductive third material fraction from the conveying stream, the eddy current separating device being arranged in such a way that conveying current from the second magnetic separating device can be transferred or discharged to the eddy current separating device and the eddy current separating device has portions located below the second magnetic separating device, facing away from the first magnetic separating device.
An apparatus configured to separate feed material, comprising:
- a first magnetic separating device adapted to separate a first ferromagnetic material fraction,
- a second magnetic separating device adapted to separate a second ferromagnetic material fraction,
- a conveying device adapted to supply a conveying stream to the first magnetic separating device,
- a further conveying device adapted to supply the conveying stream to the second magnetic separating device,
- wherein the conveying device and the further conveying device are arranged such that redistribution and/or reallocation of the material of the conveying stream takes place between the first magnetic separating device and the second magnetic separating device and that the conveying direction of the conveying device extends at an angle α of greater than 90° to the conveying direction of the further conveying device,
- wherein the second magnetic separating device is at least in part arranged below the further conveying device, facing away from the first magnetic separating device and the second magnetic separating device is a rotatable magnetic drum,
- an eddy current separating device configured to separate, after the second separation at least one non-magnetic and electrically conductive third material fraction from the conveying stream, the eddy current separating device being arranged in such a way that conveying current from the second magnetic separating device can be transferred or discharged to the eddy current separating device and the eddy current separating device has portions located below the second magnetic separating device, facing away from the first magnetic separating device.
