Der Zweck des neuen Verfahrens ist die Herstellung eines künstlichen Düngemittels, das aus Thomasphosphatmehl und Ammoniaksalz, hergestellt ist. . '■'■■■ The purpose of the new process is to produce an artificial fertilizer made from Thomas phosphate flour and ammonia salt. . '■' ■■■
Die Herstellung eines künstlichen Düngemittels aus den beiden oben genannten Komponenten scheiterte bislang an dem Umstände," daß Thomasmehl freien Kalk enthält, welcher beim Mischen mit Ammoniaksalz AmmoniakThe production of an artificial fertilizer from the two above-mentioned components has so far failed due to the circumstances, " that Thomas flour contains free lime, which when mixed with ammonia salt, ammonia

Bei dem neuen Verfahren wird die Eigenschaft des Thomasmehles, das Ammoniak zu verflüchtigen, dadurch aufgehoben, daß'.'der:'In the new process, the property of Thomas flour, the ammonia to volatilize, canceled by the fact that '.' the: '

;. in der Lauge höchstens so viel freie Säure vorhanden ist, als zur Bindung des freien Kalkes der zuzusetzenden Thomasschlacke nötig ist. Nach dem Ausblasen der Mischung, um eventuell vorhandenes freies Ammoniak in den Betrieb zurückzuführen, wird der zu steifem Brei gewordene erkaltete Inhalt der Apparate getrocknet und streufähig gemahlen. Dieses Verfahren kann für periodischen und kontinuierlichen Betrieb angewendet werden.;. in the lye there is at most as much free acid as to bind the free lime the Thomas slag to be added is necessary. After blowing out the mixture to eventually Returning any free ammonia to the plant becomes what has become a stiff pulp The cooled contents of the apparatus are dried and ground until they are ready for spreading. This method can be used for periodic and continuous operation.
Die Analysen des nach dem neuen Verfahren gewonnenen Düngers ergaben, daß die Zitratlöslichkeit der Phosphorsäure sich in weit geringerem Grade geändert hat als bei Anwendung von ebensoviel Schwefelsäure, wie neben dem Ammoniumsulfat in der Lauge enthalten war, für sich allein, und daß freier Kalk nicht mehr vorhanden ist.The analyzes of the fertilizer obtained by the new process showed that the citrate solubility the phosphoric acid has changed to a far lesser extent than when it was applied of as much sulfuric acid as is contained in the lye in addition to the ammonium sulphate was, by itself, and that free lime is no longer available.
