Abstract: A tramp metal separation device for removing contaminants from a stream of raw materials that is being conveyed by a pneumatic conveying line. The tramp metal separation device includes a first housing, a drawer, and at least one actuator. The first housing has an inlet and an outlet that are connectable to the pneumatic conveying line. The drawer is supported with respect to the first housing such that the drawer is moveable between an extended position, where a plurality of magnets are positioned within the first housing and a retracted position, where the magnets are positioned outside of the first housing. A wiper assembly removes contaminants from the magnets as the drawer moves from the extended position to the retracted position. The actuator moves the drawer between its extended position and its retracted position.

Abstract: A tramp metal separation device includes a first housing having an inlet and an outlet, a first drawer and a second drawer. The first drawer and the second drawer each have a plurality of magnets and a wiper assembly, where each drawer is supported with respect to the first housing such that each first drawer is moveable between an extended position and a retracted position. In the extended position, the magnets of the respective drawer are positioned within the first housing and are adapted to be in contact with the stream of raw materials. In the retracted position, the magnets of the respective drawer are positioned outside of the first housing. The wiper assembly of each drawer removes contaminants from the magnets as the respective drawer moves from the extended position to the retracted position.
