Description

Verfahren zur Herstellung eines Düngemittels. Der sogenannte Endlaugenkalk zeigt eine ungleichmäßige Beschafenheit, die einerseits durch die Verschiedenartigkeit des Rohralkes (je nach dem Gefüge der verwendeten Kalksteinarten, Marmorkalk bzw. Muschelkalk), anderseits .durch das Verfahren selbst bedingt sind:. Die bei dem genannten Verfahren in Erscheinung tretenden Übelstände sind hauptsächlich: r: nicht vermeidbares Vorkommen ungelöschter Kalksteine, 2. mehr oder weniger siarke Klumpenbildung, . 3. die Tatsache, :daß nachträgliches Vermahlen oder mechanisches Zerkleinern we. gen seiner .hygroskopischen Eigenschaft praktisch nicht durchführbar ist, weshalb die Herstellung einer en-,vandfrei masahinenstreufähibgen Ware in einem einzigen zusammenhängenden Arbeitsgang nicht zu erzielen ist. Entgegen dein bisherigen Verfahren, wo ein Rühren und Bewegen der Masse vor gänzlicher Abkühlung, d. h. vor Ablauf der beendeten Umsetzung von Kalk und Lauge, nicht erfolgen durfte, sieht die vorliegende Erfindung diese Umsetzung während eines Rührprozesses vor, wobei ein sofort verwendbares, maschinenstreufähiges Erzeugnis erzielt wird. Alus gemahlenem, frisch gebramltern Stückenkalk und der erforderlichen Menge Lauge entsteht bei inniger Vermischung und ständügem Rühren ein derartiges Erzeugnis im I@alufe von etwa r bis 2 Stunden.Process for the production of a fertilizer. The so-called end-lye lime shows an uneven texture, which is caused on the one hand by the diversity of the pipe limestone (depending on the structure of the types of limestone, marble limestone or shell limestone) and on the other hand by the process itself :. The evils that appear in the process mentioned are mainly: r: unavoidable occurrence of unquenched limestone, 2. more or less strong lump formation,. 3. the fact that: subsequent grinding or mechanical comminution we. Due to its .hygroscopic property is practically not feasible, which is why the production of an en-, vand-free masahinenstreufähibgen product in a single coherent operation cannot be achieved. Contrary to your previous method, where stirring and moving of the mass before complete cooling, ie before the end of the conversion of lime and lye, was not allowed, the present invention provides for this conversion during a stirring process, whereby an immediately usable, machine-spreadable product is achieved will. Alus ground, freshly baked lump of lime and the required amount of lye, when thoroughly mixed and constantly stirred, produces such a product in the course of about r to 2 hours.
