Abstract
System and method for a continuous process for separating particles according to their magnetic properties such as Curie point includes a feed of hot particles having different magnetic properties on a moving surface spaced above a stationary magnetic assembly. The temperature of the bed of particles is controlled to enable selective separation of different factions of particles based upon the temperature of the particles. The magnets are maintained substantially below their Curie point. Gaseous nitrogen is fed into and from the inside of the magnetic assembly to enhance the cooling of the magnetic assembly and to inhibit oxidation. The gas exits through high temperature bearings to inhibit debris therein. A thermal shield is placed between the moving surface and the magnets and below tubes carrying a cooling fluid to maintain magnets substantially below their Curie point. The entire process is contained with an inert gas-purged cabinet.
