ABSTRACT:
A digesting system for disposal and separation of the component materials, including potentially toxic materials, from used fluorescent tubes, wherein the fluorescent tubes are fractured with a rotating fracture blade while passing stripping air through the fracture zone and the fractured glass is then passed countercurrently through a countercurrent flow zone with a rapid flow of stripping air. As the fractured glass particulates descend or fall through the countercurrent flow stripping gas zone, they impact upon a plurality of baffles or impact surfaces that jar the particulates separating additional small powder particulates from the surface of the glass particles. The small dust or powder particulates separated from the glass by the air stream and the jarring surfaces are then separated from the air stream by a sequence including an initial cyclone or the like from which particulate material collected may be removed during continued operation and by subsequent fine filter means and a final activated carbon filter to remove metallic vapors.
