KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Nach vorliegendem Verfahren ist die Verwertung des Rohcarnallits zu einem haltbaren Düngemittel ermöglicht, und zwar besteht das Verfahren darin, daß Rohcarnallit mit kohlensaurem Kalk oder Ätzkalk zusammen kalziniert wird.According to the present process, the utilization of the raw carnallite is a durable one Fertilizer allows, namely the process consists in that raw carnallite with carbonate of lime or quick lime is calcined together.
Auf diese Weise wird ein Teil des Chlormagnesiums unwirksam gemacht und ein lockeres, gut vermahlbares DüngerpräparatIn this way some of the magnesium chloride is rendered ineffective and a loose, well-grindable fertilizer preparation
ίο erhalten, welches den Kalk zum Teil in leicht aufnehmbarer Form als Ätzkalk, zum Teil in auf die Pflanzen· allmählich wirkender Verbindung als kohlensauren, in geringem Teil auch als schwefelsauren Kalk enthält. Das Düngemittel besitzt, noch den Vorzug, daß es dem Einfluß der Luft gut widersteht und sich gut ausstreuen läßt. Je nach Bedarf ist durch Zusatz von entsprechenden Mengen Kalk und durch entsprechendes Kalzinieren ein mehr oder minder hoher Gehalt an Ätzkalk zu erzielen.ίο get, which the lime partly in easily absorbable form as quick lime, partly in a compound that gradually acts on the plants contains as carbonate, to a small extent also as sulfuric acid lime. That Fertilizer still has the merit that it withstands the influence of air well and spreads well. Depending on your needs, you can add appropriate amounts Lime and, through appropriate calcination, a more or less high content of quick lime to achieve.
Nach dem vorliegenden Verfahren wird der Carnallit in ein brauchbares Handelsprodukt übergeführt. Dasselbe Präparat ist nicht zu erzielen durch ein mechanisches Mengen von kalziniertem Carnallit und Ätzkalk, sondern nur durch vorheriges Mischen und darauf folgendes Kalzinieren.According to the present process, the carnallite is converted into a usable commercial product. The same preparation is not to be achieved by a mechanical amount of calcined carnallite and quick lime, but only by prior mixing and subsequent calcination.
Nur so wird die Bildung eines lockeren, leicht vermähl- und ausstreubaren Produktes erzielt, während Carnallit, allein kalziniert, ein steinhartes Produkt liefert. Der Luft ausgesetzt, zieht der kalzinierte Carnallit begierig Wasser an und zerfließt in Kürze; bei dem nach vorliegendem Verfahren ^* gewonnenen j Produkt hingegen ist die Wasseraufnahme belanglos.This is the only way to create a loose, easy-to-grind and spread product obtained, while carnallite, calcined on its own, provides a rock-hard product. Exposed to the air the calcined carnallite eagerly attracts water and soon dissolves; in which By contrast, the product obtained according to the present process is the water absorption irrelevant.
Nach vorliegendem Verfahren wird ferner der Chlorkaliumgehalt um 5 bis 6 Prozent erhöht, so daß bei Verwendung eines normalen Rohcarnallits von etwa 16 Prozent Chlorkaliumgehalt ein Produkt erhalten wird, welches den für Gruppe 4 der Salze bestehenden Vorschriften des Verkaufssyndikats der Kaliwerke genügt; der -Gehalt an Chlormagnesium geht um 5 bis 7 Prozent zurück.The present method also increases the potassium chlorine content by 5 to 6 percent increased, so that when using a normal raw carnallite of about 16 percent Potassium chlorine content a product is obtained, which is the existing for group 4 of the salts Provisions of the sales syndicate of the potash works are sufficient; the content of magnesium chloride goes down by 5 to 7 percent.
Als vorteilhaftes Verhältnis bei Herstellung eines derartigen Düngemittels sei beispielsweise angegeben: 20 Teile Rohcarnallit, 3 Teile Kalk von 92 bis 98 Prozent Ca CO3. Als Versuchsresultate seien folgende angeführt: An advantageous ratio in the production of such a fertilizer is given, for example: 20 parts of raw carnallite, 3 parts of lime from 92 to 98 percent Ca CO 3 . The following are the test results:
Rohcarnallit und Kalk (sogenannter Duckstein) vor dem Kalzinieren: KCl: 15,0 Prozent, 15,4 Prozent, 15,9 Prozent, 15,4 Prozent, 15,9 Prozent; nach dem Kalzinieren: KCl: 21,0 Prozent, 21,0 Prozent, 21,8 Prozent, 20,4 Prozent, 21,4 Prozent; vor dem Kalzinieren: CaCO5: 11,7 Prozent, 11,8 Prozent, 11,6Prozent; nach dem Kalzinieren: CaCO3: 8,2 Prozent, 10,3 Prozent, 10,3 Prozent und Ca O: 5,2 Prozent, 4,5 Prozent, 3,8 Prozent.Raw carnallite and lime (so-called Duckstein) before calcination: KCl: 15.0 percent, 15.4 percent, 15.9 percent, 15.4 percent, 15.9 percent; after calcination: KCl: 21.0 percent, 21.0 percent, 21.8 percent, 20.4 percent, 21.4 percent; before calcination: CaCO 5 : 11.7 percent, 11.8 percent, 11.6 percent; after calcination: CaCO 3 : 8.2 percent, 10.3 percent, 10.3 percent and CaO: 5.2 percent, 4.5 percent, 3.8 percent.
