ABSTRACT:
A self-cleaning grate magnet made up of an enclosure having a discharge duct adjacent a product duct separated by a partition and a magnet tube frame having magnetic tubes fixed thereto. The magnetic tubes extend through first holes in the enclosure, the discharge duct and through second larger holes in the partition and into the product duct where the magnetic tubes collect ferrous material on their surface. Wiper bushings are slidably received on the magnetic tubes and disposed in the discharge duct. The wiper bushings are too large to pass through the second holes in the enclosure in the partition. The holes in the partition between the discharge duct and the product duct are substantially larger than the magnetic tubes so that ferrous material is carried by the magnetic tubes into the discharge duct. The wiper bushings are stopped by the discharge duct walls and wipe the ferrous material from the magnetic tubes as the magnetic tubes are pulled through the product duct. The wiper bushings have wiper rings having a unique shape that provides improved cleaning action.
