  • System for sorting metallic objects
    Patent number: 11958058
    Abstract: A system for sorting metallic objects by magnetic separation has an electromagnetic core. The electronic core includes at least a first portion, a second portion, and a bottom. A sorting flap is arranged facing the electromagnetic core to fashion a circulation space for a conveyor of objects to be sorted from the first portion toward the second portion. The sorting flap includes a magnetic element arranged to form an air gap (E1) between the first portion and the sorting flap. The air gap forms a magnetic barrier opposing the passage of non-magnetic metallic objects, such that the objects are ejected from the conveyor. The second portion is arranged to ensure a return of the magnetic flux lines toward the first portion.
