ABSTRACT:
The plant for the thermal treatment of material, in particular scrap material, comprises at least a reaction zone within a rotary kiln having the longitudinal axis inclined of an angle in the range 0°±45° with regard to an horizontal plane and provided of first heating means and of at least a rotary screw having second heating means. The screw shaft is hollow and has, at least locally, apertures allowing the flow of gas from and/or into the reaction zone, a plurality of thermally conductive particles being movable within the reaction zone.
