Method and apparatus for the processing of non-ferrous metal - solid wastes such as dross, scrap metal, slags and ashes, in particular of aluminum - scabies

摘要

Aluminum scrap, dross, and the like is preheated to a temperature of approximately 600 DEG C in a prewarming drum and is then turbulenced in an input funnel leading to a satellite furnace. That turbulencing is effected by feeding the preheated aluminum pieces into a stream of molten aluminum coming from a primary smelting oven and directed tangentially into the input funnel so as thoroughly to turbulence the particles and molten aluminum together. Dross developing in the satellite furnace is compacted and then removed and grouped up for reintroduction to the preheating step so as to extract all of the aluminum therefrom.
