Eriez Magnetic Hump magnetic separators remove tramp iron contamination from gravity or pneumatically fed dry, free-flowing products such as feed, grain and food stuffs. Materials entering the unit are forced to change direction against the face of the series SD plate magnet. As the materials tumble in the housing, they change direction once more against the face of a second plate magnet. The ferrous contamination remains on the face of the magnet until the operator swings the magnet out of the product flow and physically removes the metal. Various magnetic strengths can be selected to suit specific application challenges. The separators are also available in a self-cleaning design.
