Description

Verfahren zur Herstellung eines Düngemittels. Die Erfindung bezweckt, aus mineralischem kohlensaurem Kalk ein leicht assimilierbares, streufähiges, pulverförmiges Düngemittel zu gewinnen.Process for the production of a fertilizer. The invention aims from mineral carbonate of lime an easily assimilable, spreadable, powdery one To gain fertilizers.

Zu diesem Zweck werden Kalksteinstückchen gemahlen, dann mit einer Salzlösung, z. B. Chlormagnesiumlösung, getränkt und die entstehende feuchte Masse mit wasserentziehenden Mitteln vermischt.For this purpose, pieces of limestone are ground, then with a Saline solution, e.g. B. magnesium chloride solution, soaked and the resulting moist mass mixed with dehydrating agents.

Als Ausgangsstoff können die in den sogenannten Kummerhaufen der Kalksteinbrüche enthaltenen Kalksteinreste dienen. Diese werden abgesiebt und gemahlen. Die Schutthaufen, die für die Steinbrüche eine große Last waren, werden so einer nutzbaren Verwendung zugeführt. Als Salzlösung kommen die Endlauge der Kaliwerke, die Abfälle der Salinen usw. in Betracht.The starting material can be found in the so-called Kummerhaufen of the limestone quarries contained limestone residues are used. These are sieved and ground. The piles of rubble which were a great burden for the quarries, thus become a useful use fed. The final liquor from the potash works, the waste from the salt pans, is used as the salt solution etc. into consideration.

Als wasserentziehendes Mittel kann man z. B. gepulverten Bergkieserit, Asche, Magnesia u. dgl. benutzen.As a dehydrating agent you can, for. B. powdered mountain gravel, Use ash, magnesia, and the like.

Das entstehende Erzeugnis ist ein sehr lockeres Pulver.The resulting product is a very loose powder.

Ätzende Wirkungen, welche anorganische Salze, vornehmlich Chloride, bei ihrer Verwendung als Düngemittel häufig zeigen, treten infolge der Anwesenheit des kohlensauren Kalkes nicht auf.Corrosive effects caused by inorganic salts, mainly chlorides, when used as fertilizers often show occur as a result of the presence of carbonate of lime does not arise.

Die beschriebene Behandlung erhöht die Assimilierbarkeit des mineralischen kohlensauren Kalkes wesentlich.The treatment described increases the assimilability of the mineral carbonate of lime is essential.

Man hat bereits den Scheideschlamm von Zuckerfabriken als Düngemittel vorgeschlagen. Auch dieser enthält kohlensauren Kalk in feinverteilter, leicht assimilierbarer Form, doch ist die Menge des Scheideschlammes so beschränkt, daß sie bei weitem nicht ausreicht, den Bedarf an kohlensaurem Kalk zu decken. Außerdem führt er leicht zu Brand- und Schorfbildung.You already have the sludge from sugar factories as fertilizer suggested. This also contains carbonate of lime in finely divided, easily assimilable form Shape, but the amount of sludge is so limited that it is by far not enough to meet the need for carbonate of lime. He also leads easily to burn and scab formation.
