Description
Verfahren zur Herstellung eines Düngemittels. Zusatz zum Patent 391758*). Von dem gemäß dem Verfahren des Hauptpatents zu verwendenden Kalk bzw. der Magnesia kann ein Teil mit Vorteil durch solche wasserfreie Salze ersetzt werden, die Wasser als Kristallwasser zu binden vermögen. Dabei ist es nicht immer erforderlich, an Stelle des ersetzten Kalkes oder der Magnesia die gleiche bzw. äquivalente Menge an entwässertem Salz anzuwenden; vielmehr läßt sich in der Regel eine bestimmte Menge von Kalk oder Magnesia durch eine etwas geringere Menge entwässerten Salzes ersetzen.Process for the production of a fertilizer. Addition to patent 391758 *). Of the lime or magnesia to be used according to the method of the main patent a part can be replaced with advantage by such anhydrous salts, the water able to bind as crystal water. It is not always necessary to do this Place the replaced lime or magnesia the same or equivalent amount apply to dehydrated salt; rather, as a rule, a specific Amount of lime or magnesia from a slightly smaller amount of dehydrated salt substitute.
So wurden beispielsweise 330 kg Ablauge (3.4° B6) schon durch 25 kg gebrannten Kalk und 25 kg entwässertes Magnesiumsulfat in trockenes, mahl- und streufähiges Düngemittel verwandelt. Die Kristallwasserverbindung geht genügend langsam vor sich, um die Mischung der Masse an sich sowie die eventuelle Zumischung von Torfmull und anderen Stoffen, die jedoch nicht unbedingt erforderlich ist, bequem durchführen zu können. Die Masse nimmt z. B. wesentlich langsamer die als Zwischenstadium des Trockenprozesses eintretende zähe Beschaffenheit an, wie z. B. Ablauge mit Kalk allein im Gemisch mit Torfmull. Das erwähnte entwässerte Magnesiumsulfat hat sich besonders gut für den vorliegenden Zweck geeignet erwiesen. Doch läßt sich eine ähnliche Wirkung auch mit anderen entwässerten Salzen für sich oder in Gemischen, z. B. Kalium-Magnesiumchlorid, Natriumsulfat, Calciumsulfat, Calcium-Natriumsulfat, Calciumphosphat, Magnesiumphosphat u. dgl., erzielen. Doch bietet die Verwendung von Magnesiumsulfat noch den Vorteil, daß leicht ein auch für den Boden besonders günstiges Verhältnis von 3 Ca0 zu z Mg0 erzielt wird, was bei der zunehmenden Bedeutung der Magnesiadüngung für bestimmte Landeserzeugnisse (z. B. Rüben, Kartoffeln usw.) von besonderer Wichtigkeit ist.For example, 330 kg of waste liquor (3.4 ° B6) were converted into dry, grindable and spreadable fertilizer with 25 kg of quicklime and 25 kg of dehydrated magnesium sulphate. The water of crystallization is sufficiently slow that the mixture itself and the possible addition of peat waste and other substances, which, however, is not absolutely necessary, can be carried out comfortably. The mass takes z. B. much slower the occurring as an intermediate stage of the drying process toughness, such. B. Waste liquor with lime alone in a mixture with peat litter. The dehydrated magnesium sulfate mentioned has proven particularly suitable for the present purpose. However, a similar effect can also be achieved with other dehydrated salts alone or in mixtures, e.g. B. potassium magnesium chloride, sodium sulfate, calcium sulfate, calcium sodium sulfate, calcium phosphate, magnesium phosphate and the like., Achieve. However, the use of magnesium sulphate also offers the advantage that a ratio of 3 Ca0 to z Mg0, which is particularly favorable for the soil, is easily achieved, which, given the increasing importance of magnesia fertilization for certain national products (e.g. beets, potatoes, etc.) is of particular importance.
