Abstract

An arcuate shaped magnetic system is housed in a fixed cryostat within a rotating drum. A slurry containing magnetizable particles is charged into an operating area defined by the magnetic system at the lower part of the drum and magnetic particles adhering to the drum are removed as the drum rotates the same to a discharge location. The cryostat has an outer wall which conforms to the shape of the drum and houses a sector-shaped refrigeration tank. The refrigeration tank has an arcuate wall section conforming to the shapes of the cryostat wall and the drum and is positioned in close proximity to the outer cryostat wall only in the operating area in order to minimize inward heat transfer.
