System for cleaning metallic scraps from organic compounds

A system for cleaning metallic scraps from organic compounds comprising:

• a first chamber provided with an inlet for the scraps and a second chamber provided with an outlet for the scraps,
• a device for controlling the atmosphere in the first chamber and in the second chamber, the oxygen content in the second chamber being above the oxygen content in the first chamber;
• a temperature controller for heating the first chamber at a temperature adapted to provide pyrolysis of at least a part of the organic compounds and for heating the second chamber at a temperature adapted to provide burning of at least a part of residues of the pyrolysis;
• a conveying assembly for conveying scraps from the inlet for scraps in the first chamber toward the outlet for scraps in the second chamber;
• the conveying assembly comprising:
• a first linear guiding mechanism for conveying scraps in the first chamber and a second linear guiding mechanism for conveying scraps in the second chamber,
• a transversal chute between the first chamber and the second chamber, wherein the scraps freely fall from the first chamber to the second chamber;
• a driving device for driving the first linear guiding mechanism and the second linear guiding mechanism at adjustable speed, the driving device being capable of driving the first guiding mechanism at a different speed than the second linear guiding mechanism, so that the thickness of the layer of scraps in the second chamber is adjustable with regards to the thickness of the layer of scraps in the first chamber.
