Claim Text:
1. An apparatus for separating hot particles including a plurality of materials having different magnetic properties, the apparatus comprising: a plurality of permanent magnets arranged in a magnet assembly and configured to create a magnetic flux capable of providing a coercive force on at least a portion of said particles; a moving surface proximate said magnet assembly for carrying said particles in a downward path through said magnetic flux while said coercive force attracts said portion of said hot particles toward said moving surface; a feed system for supplying said particles onto said moving surface; and a cooling system for maintaining the temperature of said magnets substantially below their Curie point, said cooling system comprising a pair of plates which are disposed between said magnet assembly and said moving surface, said cooling system configured to operate by passing a contained cooling fluid through a gap between said pair of plates, wherein at least one barrier is provided within the gap to lengthen a coolant flow path defined within the gap.
