Abstract
The present invention relates to a furnace intended for the thermal treatment of solid materials, comprising a rotary element (1) in which said solid materials circulate longitudinally, and a means (9) for heating said materials, which extends longitudinally in the furnace, the solid materials moving forward through about two lengths inside the rotary element (1). According to the invention, the heating means (9) is stationary, intended for channelling the solid materials and for preheating them. More specifically, the heating means (9) is arranged coaxially and inside the rotary element (1) so that, in the axial zone delimited by the heating means, the solid materials exhibit the highest temperatures.
