ABSTRACT:
A magnetic separator made up of a drum bearing a plurality of stacked spaced rings each having a U-shaped cross section in the form of an arc outwardly facing channels. An upper set of magnets and a lower set of magnets supported on the separator frame and extending into the channels and matrix module are supported on the rings in spaces between the rings. A mixture of magnetic and non-magnetic material is fed onto the matrix modules and first upper nozzles spray water on the matrix modules as the matrix modules pass between the upper magnets thereby flushing non-magnetic material. The second upper nozzles spray water on the matrix modules as the modules move away from the upper magnets so that magnetic material is flushed from the matrix modules and falls into the non-magnetic hopper. The magnetic material is fed from the hopper onto the modules of the matrix material between the lower magnets and the non-magnetic residue is separated from the matrix module by the lower nozzle as the material passes between the lower magnets. The magnetic residue is washed from the matrix material as the material moves out of the fields of the lower magnets. The magnetic residue falls into a receptacle. The rings may be fabricated from fiberglass and polymer resin. The rings are clamped in spaced relation by bolts and spacers. The matrix is accordion folded sheet material.
