Claims
- 1. A ferrous metal object separator removably attachable to a ferrous metal surfaced conveyor for transporting a moving stream of commingled non-ferrous material and ferrous metal objects, said separator comprising:(a) an inclined surface extending upwardly from a leading edge to a trailing edge; (b) a separating magnet for magnetically retaining said ferrous metal objects without substantially impeding transport of said non-ferrous material along said conveyor; and (c) a fastening magnet for removably magnetically fastening said separator on said ferrous metal surface; said inclined surface and said separating magnet being stationary parts of said separator, said separator being movable with said conveyor.
- 2. A separator as defined in claim 1, wherein said separating magnet is embedded in said separator adjacent said trailing edge.
- 3. A separator as defined in claim 2, wherein said fastening magnet is embedded in said separator.
- 4. A separator as defined in claim 2, wherein said separator is formed of a non-ferrous material and has a width slightly smaller than the width of said conveyor.
- 5. A separator as defined in claim 1, wherein said fastening magnet is embedded in said separator.
- 6. A separator as defined in claim 5, further comprising at least one pry bar recess formed in an outward edge of said separator.
- 7. A separator as defined in claim 5, further comprising at least one pry bar recess formed in a lower outward edge of said separator.
- 8. A separator as defined in claim 1, wherein said separator is formed of a non-ferrous material and has a width slightly smaller than the width of said conveyor.
- 9. A separator as defined in claim 1, further comprising at least one pry bar recess formed in an outward edge of said separator.
- 10. A separator as defined in claim 1, further comprising at least one pry bar recess formed in a lower outward edge of said separator.
- 11. A method of removing ferrous metal objects from a moving stream of non-ferrous material commingled with said ferrous metal objects, said method comprising:(a) removably magnetically fastening said inclined surface in a fixed position relative to said moving stream; (b) diverting said moving stream across an inclined surface having an abrupt trailing edge; and (c) applying a magnetic field near said trailing edge to magnetically retain substantially all said ferrous metal objects near said trailing edge without substantially impeding movement of said non-ferrous material; while maintaining said inclined surface stationary relative to said separating magnet.
