A magnetic separator having intersecting conveyor belts, in which the lower belt is used to transport the material to be separated, while the upper belt discharges the separated material, and in which a frame having a closed permanent-magnet system is arranged on each side of the discharge belt, each frame consisting of four directionally magnetized block magnets connected together in pairs by means of soft-iron parts, and of soft-iron intermediate parts connected together by soft-iron pole-pieces forming a working air-gap.

A magnetic separator having intersecting, elongated, endless conveyor belt means positioned one above the other with each said conveyor belt means being defined by an upper and lower run, the lower belts means serving to transport the material to be separated and the upper belt means serving as discharge means for the separated material as well as first and second soft-iron pieces forming the working gap and being magnetized in opposite directions by a magnetic system with the first pole piece being arranged below the upper run of the lower belt means and the second pole piece being arranged above the lower run of the upper belt means, the first pole piece having a pole surface of large area and the second pole piece having at least one smaller pole surface for concentrating the magnetic flux and extending in the longitudinal direction of the upper belt means, said magnetic system comprising two frames that are spaced apart in the direction of the lower belt means with each of said frames surrounding the upper run of the lower belt means, one of said frames being arranged along each of the longitudinal sides of the upper belt means, said frames comprising two symmetrical halves of alternatingly successive permanent magnets and soft-iron parts, said frames being connected by said two first mentioned soft-iron pole pieces.
