<p>2113545 9301888 PCTABS00019 The separation of potentially toxic phosphor compounds from fractured glass particulates derived from crushing used fluorescent light tubes is improved by continuously mixing the fractured glass particulates together in surface contact with each other to abrade the toxic phosphors from the surfaces of the glass particulates followed by separation by air stripping of the small phosphor particles from the fractured glass particulates. The stripping usually is done in a separate stripping chamber (51). The mixing and abrading may be accomplished in a variety of mixing devices including auger-type apparatus (43), rotary chambers, fluosolids reactors and others.</p> |
