  • Magnetic decontamination device and method
    Patent number: 6350296
    Abstract: A device and method for removing metalliferous particles from a powder so that the powder can be reused. A contaminated powder fluid stream flows down tube (6/7) into zones A, B and C adjacent the surface of a magnet (4). The flow flows past the surface of the magnet (4) and is directed towards the surface of the magnet (4) by baffles (10A, 10B). The magnet (4) separates metallic particles from powder particles and these metallic particles are removed from the face of the magnet (4) by scraper bars (21) conveyed by endless belts (22) supported by roller sets (23). The device can also include a fan (5) for promoting the movement of air in a counter direction to the delivered powder mixture.
