Abstract
An apparatus for separating hot particles including a plurality of materials having different magnetic properties includes 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 the particles, a moving surface proximate the magnet assembly for carrying the particles in a downward path through the magnetic flux while the coercive force attracts the portion of the hot particles toward the moving surface, a feed system for supplying the particles onto the moving surface, and a cooling system for maintaining the temperature of the magnets substantially below their Curie point, the cooling system comprising a pair of plates which are disposed between the magnet assembly and the moving surface, the cooling system configured to operate by passing a contained cooling fluid through a gap between the pair of plates.
