Description
Lagerung von ammonnitrathaltigen Mischdüngern. Es ist bekannt, daß ammonitrafhaltige Mischdünger beim Lagern nach kurzer Zeit erhärten. So werden Ammonsulfatsalpeter und Kaliammonsalpeter, auch wenn sie in feinster Form gemischt werden, so hart, daß nach kurzer Lagerzeit die Entnahme infolge der Bildung eines festen Blockes äußerst schwierig ist. Diese blockähnliche Masse wurde früher durch Sprengkörper zertrümmert und die einzelnen Blöcke dann in geeigneter Mahlvorrichtung feinstens zermahlen, bevor sie zur Verwendung gelangte. Diese Methode der Sprengung mußte verlassen werden, nachdem sich herausgestellt hat, daß der Ammonsalpeter, wenn er auch mit nichtexplosiven Stoffen vermischt wird, seine explosive Eigenschaft nicht verliert. Da Ammonitrat in verschiedenen Modifikationen vorkommt, welche verschiedenes Volumen besitzen, so ergab sich, daß die Ursache des Erhärtens der ammonitrathaltigen Mischungen auf diese Volumenveränderung zurückzuführen. ist und nur vollständig vermieden wird, wenn der Übergang der Modifikation ineinander verhindert wird. Das geschieht nach vorliegender Erfindung dadurch, daß die Lagerung der Masse bei Temperaturen von über 32° vorgenommen wird.Storage of mixed fertilizers containing ammonium nitrate. It is known that Mixed fertilizers containing ammonia harden after a short period of time during storage. This is how ammonium sulphate nitrate becomes and potassium ammonium nitrate, even if they are mixed in the finest form, so hard, that after a short storage period the removal due to the formation of a solid block is extremely difficult. This block-like mass was formerly used by explosive devices smashed and the individual blocks then finely in a suitable grinding device grind it up before using it. This method of demolition had to be left after it has been found that the ammonium nitrate if he even if it is mixed with non-explosive substances, its explosive properties are not loses. Since ammonitrate occurs in different modifications, which ones are different Have volume, it was found that the cause of the hardening of the ammonitrate-containing Mixtures attributed to this change in volume. is and only complete is avoided if the transition of the modification into one another is prevented. That happens according to the present invention in that the storage of the mass at temperatures of over 32 °.
B e i s p i e 1. i oo g Ammonxtrat werden mit etwa 12 o bis 17 5 g Ammoniaksulfat innigst gemischt. i. ioo g des Gemisches werden bei gewöhnlicher Temperatur in ein Papprohr eingefüllt und; durch leichtes Klopfen verdichtet. Die Masse läßt man etwa 2 bis 3 Wochen bei gewöhnlicher Temperatur lagern. Nach Entfeinung der äußeren Umhüllung ist die Masse nach dieser Zeit zu einem Block zusammengebacken, der nur schwer zu zertrümmern ist. Beim Zerschlagen zerfällt derselbe in einzelne Stücke, die, wenn man. sie in Pulverform erhalten will, nochmals gemahlen werden müssen.B eispie 1. i oo g Ammonxtrat o are mixed intimately with about 12 to 1 7 5 g of ammonia sulphate. i. 100 g of the mixture are poured into a cardboard tube at ordinary temperature and; compacted by light tapping. The mass is left to store for about 2 to 3 weeks at ordinary temperature. After the outer coating has been thinned, the mass is caked into a block after this time, which is difficult to break. When smashed, it falls apart into individual pieces, which, if one. If you want to receive it in powder form, you have to grind it again.
2. ioo g des ob@engenannten Gemisches werden bei einer Temperatur von über 32° etwa 2 bis 3 Wochen gelagert. Die Masse ist, wenn man die Hülle entfernt, ebenfalls in Blockform vorhanden; keineswegs ist sie jedoch in einem solchen Umfange und in einer solchen Weise erhärtet, `vie dies bei dem Lagern bei gewöhnlicher Temperatur der Fall ist. Durch einfaches Hinwerfen oder durch leichtes Zerdrücken kann die Masse in der einfachsten Weise zerkleinert «-erden, um sie in kleiner Körnung wieder zu erhalten.2. 100 g of the above-mentioned mixture are at a temperature stored at over 32 ° for about 2 to 3 weeks. The bulk is when you remove the shell also available in block form; however, it is by no means to such an extent and hardened in such a way as when stored at ordinary temperature the case is. The The mass is crushed in the simplest possible way, in order to bring it back into small grains to obtain.
