Beschreibung
Zusammenfassung:	Procedure for the thermal treatment of fine grain material, is special for calcining cement in several phases, for which it is proceeded to precaldear the material, and finally it is finished calcining in a furnace, precalcining before entering the furnace by supplying fuel, while remaining in a current of hot gas, characterized in that the fuel is oxidized for the time being partly in the precalcining phase, and then it is joined in the hot stream of oxygenated gas with at least a substantial part of the material that has to be treated, and continues to rust.
