摘要

Device for continuously drying contaminated aluminum swarf comprises a rotating drum heated using a burner and having a first end at which the swarf is continuously introduced and a second end at which the dried swarf is ejected. An indirect heater is arranged close to the first end of the drum. The second end of the drum is structured to introduce oxygen-containing gas, especially ambient air, in a controlled manner. Preferred Features: Two burners are arranged close to the end of the drum, the first burner being aligned with the drum axis and the second burner directed onto the wall of the drum. The drum is arranged in a heating chamber having a refractory lining.
