Abstract
Components of crushed fluorescent lamps are conveyed pneumatically from a lamp crusher housing to a cyclonic hopper and enter tangentially into the hopper adjacent its upper end. The components include heavy glass particles and caps which are allowed to drop by gravity into a separator housing where they are separated from each other and discharged into different storage containers. Lighter glass particles and dust are recirculated from the upper end of the hopper back to the crusher housing. A vacuum source draws dust and vapors pneumatically from the bottom of the hopper and introduces them tangentially into a cyclone filter housing where particulate matter is allowed to drop into a dust collector. This vacuum source also draws lighter dust and vapors from the upper end of the cyclone filter housing to a dust and mercury filter. Mounted in the crusher housing is a paddle element which rotates adjacent lamp crusher blades and mechanically sweeps lamp components towards the crusher housing outlet.
