ABSTRACT:
A sintering machine for pulverulent ore concentrates containing sulfidic metals including an ignition zone, a sintering zone and at least two cooling zones wherein there is total recirculation of cooling gases between two cooling zones and including a recuperative heat exchanger for cooling the exhaust gas from the first cooling zone, prior to its introduction to the second cooling zone.
