Abstract
A high intensity magnetic field separator for the wet preparation of magnetizable particles of solids receives a charging material having a carrier medium with the particles therein through an arrangement of ferromagnetic bodies, organized as a matrix, in the area of a magnetic field. A hollow body of magnetically inert material is rotatably mounted for rotation about a vertical axis and carries a ferromagnetic body on its outer side and rotates in close proximity about at least one magnetic system which fixedly mounted within the interior of the rotating body. The hollow body is at least approximately rotationally symmetrical and is preferably a cylinder, but may take the shape of a truncated cone or a polygon. The magnetic system comprises an arrangement of superconducting coils in a cryostat which has refrigeration conduits extending down through the open of the hollow body and downwardly through the base of the machine which mounts the hollow body.
