Abstract
A magnet cleaner cooperates with one or more permanent magnets positioned over a conveyer carrying pieces of metal in non-ferrous material so as to remove the metal from the non-ferrous material. The magnet cleaner includes a frame and a capture sheet mounted to the frame and positioned on the frame so as to be substantially flush with the permanent magnets when they are in their lowered positioned. The magnets are spaced by an attenuation distance from the capture sheet when they are in their raised position. The permanent magnets, which may be mounted in a housing, are positionably mounted on the frame so as to be selectively elevatable between their lowered and raised positions upon actuation of an actuator. The actuator is positioned so as to cooperate with the permanent magnets and the frame so as to raise or lower the magnets relative to the capture sheet.
