Description
Verfahren zum sulfatisierenden Rösten und Totrösten von Kiesen, Blenden, schwefelhaltigen Erzen und Hüttenerzeugnissen aller. Art. Es ist bekannt, Erze, die im mechanischen Ofen nicht vollständig abgeröstet werden können, dadurch vollkommen ihrer letzten Schwefelanteile zu berauben oder den Schwefel zu Schwefeltrioxyd zu oxydieren, daß sie einem Verblaseprozeß unterworfen werden.Process for sulphatizing roasting and dead roasting of gravels, blends, sulphurous ores and metallurgical products of all. Art. It is known ores, which cannot be completely roasted in the mechanical oven, therefore completely To deprive them of their last sulfur content or to convert the sulfur to sulfur trioxide oxidize that they are subjected to a fading process.
Es hat sich nun herausgestellt, daßbeim Verblasen der im Röstgut enthaltene Staub die vollkommene und rasche Entschwefelung stark hindert.It has now been found that when the toasted material is blown Dust strongly prevents the complete and rapid desulfurization.
Da das heiße, aus dem mechanischen Ofen in den Totröstofen oder Verblaseofen gelangende Material nicht entstaubt werden kann, wurde beobachtet, daß ein äußerst gutes Verblasen des heiß aus dem Ofen kön=enden Materials möglich war, wenn der in dem auf den mechanischen Ofen aufgegebenen Erz enthaltene Staub vor der Aufgabe ausgesondert und in Grieß- oder Kornform verwandelt und -dann dem übriggebliebenen Korn wieder beigemischt wird.Since the hot, from the mechanical oven to the dead roasting oven or blown oven Incoming material cannot be dedusted, it has been observed that an extremely the material, which could be hot out of the furnace, was able to be blown well if the dust contained in the ore loaded on the mechanical furnace prior to loading separated and transformed into semolina or grain form and then the leftover Grain is added again.
Es bildet sich dann nur äußerst wenig Staub beim Durchwandern des Erzes durch den mechanischen Ofen, welche geringe Menge das spätere Verblasen nicht störend beeinfiußt.Very little dust then forms when wandering through the Ore through the mechanical furnace, which small amount the later blowing does not disruptively influenced.
