Metal recovery from dross

摘要

In a system for treating and managing hot aluminum dross, the dross is compacted and delivered by a pair of "squeeze" rolls in a continuous semi-solid sheet, readily broken up for further treatment or disposal. The rolls may be cooled or heated as required to condition the dross appropriately, for storage or immediate further treatment. Ribs on the rolls and/or a stepped "break" chute downstream of the rolls may be used to break the compacted dross into "patties" for convenient handling.
