Appl. No.:

8/205693

International Classification:

B03C 114

US Classification:

209 39

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.

Abstract:

A tracking system employs a strip of readily magnetizable material adhered to at least one edge of a conveyor belt used with a magnetic roll separator. The magnetic field produced by the head roller of the conveyor belt produces a continuous centering force which acts on the easily magnetized material providing proper tracking for the conveyor belt. The readily magnetizable material can be attached directly to either surface of the belt, have an edge portion of the belt wrapped around it or, in the form of a woven wire mesh, have the belt integrated into it by vulcanization. The strip of material may be continuous or intermittent.
