KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand der Erfindung ist ein Verfahren zur Herstellung eines keimtötenden Phosphatdüngemittels. The invention relates to a method for producing a germicidal phosphate fertilizer.
Wie bekannt, wirkt Schwefel in feiner Verteilung keimtötend. Im Handel findet sich Schwefel in fein verteiltem Zustande in Form von Scjnwefelblumen vor; diese Schwefelblumen sind aber für die Herstellung eines keimtötenden Düngemittels zu teuer. Praktisch ίο kommt daher nur gemahlener Rohschwefel in Betracht.As is known, sulfur in fine distribution has a germicidal effect. In the trade is found Sulfur in a finely divided state in the form of sulfur flowers; these sulfur flowers but are too expensive for the production of a germicidal fertilizer. Practically ίο only ground raw sulfur comes into consideration.
E'j gelingt nun aber nicht, den stückförmigen Schwefel in gewöhnlicher Art so fein zu mahlen, wie dies für den vorliegenden Zweck erforderlich ist, denn der Schwefel hat ..-infolge'seiner Zähigkeit große Neigung, der ^ Wirkung der Mühle Widerstand entgegenzusetzen, so daß der beim Mahlen erhaltene Schwefel eine Mischung von dichten Flocken und größeren Teilchen darstellt, die zu dem beabsichtigten Zweck unbrauchbar sind.E'j but now is not possible to grind the tablet-form sulfur in the usual way as fine as this is necessary for the present purpose, because the sulfur has to oppose ..- infolge'seiner toughness great tendency of ^ effect of the mill resistance, so that the sulfur obtained on milling is a mixture of dense flakes and larger particles which are useless for the intended purpose.
Es ist nun gefunden worden, daß man gewöhnlichen festen Schwefel in Stücken (zweite Sorte) in sehr feinen Zustand überführen kann, wenn man ihn grob pulvert und ihn mit dem grob gepulverten Phosphat zusammen vermahlt. In Gemeinschaft mit dem Phosphat läßt sich der Schwefel zu einem außerordentlich feinen, kaum fühlbaren Pulver vermählen. Praktisch erfolgt die Ausführung des Verfahrens in der Weise, daß man das Phosphatgestein und den Schwefel zuerst durch einen Vorbrecher gehen läßt, der das Gemisch zur Durchschnittsgröße einer Erbse oder Bohne überführt. Die rohe, zerkleinerte Mischung wird dann in eine Pulvermühle nach Lucops oder einem anderen System gebracht und dort fein gemahlen, indem die groben Stücke immer wieder in die Mühle zurückgegeben werden. Man erhält so eine innige und gleichmäßige Mischung von Phosphat und Schwefel in Form eines fast unfühlbaren Pulvers, das vollständig trocken ist. Man erhält in einigen Fällen sehr gute Resultate, wenn man z. B. auf i960 kg Phosphat 40 kg Schwefel anwendet und in anderen Fällen 30 bis 50 kg Schwefel auf die Tonne Mischung.It has now been found that ordinary solid sulfur can be obtained in pieces (second Variety) can be converted into a very fine state if it is coarsely powdered and mixed with the coarsely powdered phosphate ground together. In association with the phosphate the sulfur can be ground to an extraordinarily fine, barely perceptible powder. In practice, the method is carried out in such a way that the phosphate rock is removed and passing the sulfur through a primary crusher first, which takes the mixture to the average size of a pea or bean convicted. The raw, crushed mixture is then put into a Lucops powder mill or another system and finely ground there by adding the coarse pieces always be returned to the mill. In this way one gets an intimate and uniform one Mixture of phosphate and sulfur in the form of an almost imperceptible powder that is completely dry. You get in some Cases very good results if you z. B. applies 40 kg of sulfur to 1960 kg of phosphate and in other cases 30 to 50 kg of sulfur per ton of mixture.
Die Mischung von fein gemahlenem Schwefel und Phosphat kann an sich als Düngemittel verwendet werden, sie kann aber auch mit Salpeter und Kalisalzen oder mit einem von ihnen oder ähnlichen Stoffen vermischt, je nach der besonderen Bodenbeschaffenheit und der Art des Saatgutes, zur Anwendung kommen. Die Mischung wird am besten in der Fabrik vorgenommen, indem der Salpeter oder dergleichen in einer Mühle von ähnlichem System wie die, worin das Phosphat und der Schwefel gemahlen wurde, und dann mit der gemahlenen Mischung von Phosphat und Schwefel vermählen wird, wodurch man ein sehr feines und gleichmäßiges Gemisch erhält.The mixture of finely ground sulfur and phosphate can in itself be used as a fertilizer can be used, but it can also be used with saltpeter and potash salts or with one of mixed with them or similar substances, depending on the particular nature of the soil and the type of seed to be used. Mixing is best done at the factory by adding the saltpeter or the like in a mill of a similar system to that in which the phosphate and the Sulfur was ground, and then ground with the ground mixture of phosphate and sulfur, making one very fine and even mixture is obtained.
Ein praktisch wertvolles Düngemittel für Kartoffeln ist eine Mischung aus etwa 800 kg Phosphat-Schwefelgemisch, die mit 600 kg Baumwollsamenmehl, 400 kg Kainit und 200 kg Natronsalpeter zusammen gemahlen ist. Für Weizen eignet sich am besten eine MischungA practically valuable fertilizer for potatoes is a mixture of about 800 kg Phosphate-sulfur mixture made with 600 kg cottonseed flour, 400 kg kainite and 200 kg Sodium nitrate is ground together. A mixture is best for wheat
aus 800 kg Phosphat-Schwefelgemisch, die mit 800 kg Baumwollsamenmehl und 400 kg Kainit vermählen ist. Für Baumwolle betragen die Verhältnisse etwa 800 kg Phosphat-Schwefelgemisch, 600 kg Baumwollsamenmehl, 400 kg Kainit und 200 kg Magnesiumsulfat. from 800 kg of phosphate-sulfur mixture, that with 800 kg of cottonseed meal and 400 kg Kainite is wedded. For cotton the proportions are around 800 kg of a phosphate-sulfur mixture, 600 kg cottonseed flour, 400 kg kainite and 200 kg magnesium sulfate.
