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. Each of the first drawer and the second drawer is restrained against movement from the extended position to the retracted position when the other of the first drawer and the second drawer is disposed in the retracted position.
