Abstract:
1. A process for separating non-ferrous materials, the process comprising: providing rotating permanent-magnets, which produce together with non-ferrous materials, to be separated, an eddy current field, the value of the so created eddy field producing varying forces, which depend from the mass of the non-ferrous material to be separated, and hence, eject the different non-ferrous material particles in varying distances, placing the rotating permanent-magnets on rotating discs, the revolution of which can be altered by an electrical drive to adapt the so created eddy current forces to the specific needs for separation of individual non-ferrous materials to be sorted, wherein the number of discs arranged in row in transportation direction underneath of a slowly moving conveyor belt, corresponds to the number of non-ferrous metals, and wherein that the revolution of the individual discs can be controlled in adaptation to the individual separation needs of the non-ferrous metals to be separated.
