Das vorliegende Verfahren behandelt die Herstellung eines Gemisches aus Sand und Kalk für die Fabrikation künstlicher Steine. Es wird folgendermafsen ausgeübt:The present method deals with the preparation of a mixture of sand and lime for the manufacture of artificial stones. It is exercised as follows:
In eine geschlossene Mischtrommel wird Sand, der in bekannter Weise vorher getrocknet worden ist, und gebrannter Kalk oder Kalkhydrat eingebracht und erhitzte Prefslufl, die vorher zweckmäfsig von Kohlensäure befreit worden ist, eingeleitet.Sand, which has been previously dried in a known manner, is placed in a closed mixing drum has been, and quick lime or hydrated lime introduced and heated Prefslufl, the has previously been expediently freed from carbonic acid, initiated.
Bei der Anwendung von gebranntem Kalk wird die zur Löschung desselben erforderliche Menge Wasser oder Dampf in die Mischtrommel selbst eingeführt. Die Benutzung der Prefsluft hat gegenüber der Behandlung von Kalksandgemischen mit Wasserdampf den Vortheil, dafs das Gemisch, nachdem die erforderliche Menge Wasser einmal zugebracht ist, keine Aenderung des Feuchtigkeitsgehaltes mehr erleidet, während durch die Einwirkung der heifsen Druckluft die Bildung von Kalksilicat nach Angabe des Erfinders gleichzeitig wesentlich begünstigt wird.When using quick lime, that is necessary to extinguish it Amount of water or steam introduced into the mixing drum itself. The use of the pre-filled air has the advantage over the treatment of sand-lime mixtures with steam that the mixture, once the required amount of water has been added, does not change the moisture content suffers more, while under the action of the hot compressed air According to the inventor, the formation of lime silicate is at the same time significantly favored will.
Der Druck, unter dem die Bereitung des Gemisches vor sich geht, sowie die Dauer des Mischens sind auf Grund praktischer Erfahrungen mit Berücksichtigung der Art der jeweilig verwendeten Stoffe festzustellen.The pressure under which the preparation of the mixture takes place, as well as the duration of the Mixing are based on practical experience, taking into account the nature of the respective determine the substances used.
Das vorliegende Verfahren erstreckt sich aber nur auf die Herstellung des ungeformten Gemisches, nicht auf die Behandlung bereits geformter Kalksandsteine mittelst Druckluft.However, the present process only extends to the production of the unformed mixture, does not apply to the treatment of already formed sand-lime bricks by means of compressed air.
Das Wesen der Erfindung wird nicht geändert, wenn an Stelle von vorher getrocknetem Sand naturfeuchter oder vorher besonders angefeuchteter Sand Verwendung findet. In diesem Fall ist natürlich entsprechend weniger Wasser oder Dampf in die Mischtrommel zum Ablöschen des Kalkes einzuführen. Auch ist es gestattet, Sand und Kalk nach einander in die Mischtrommel einzubringen.The essence of the invention is not changed if in place of previously dried Sand naturally moist or previously specially moistened sand is used. In this Case is of course correspondingly less water or steam in the mixing drum for extinguishing to introduce the lime. It is also permitted to add sand and lime one after the other to the Bring mixing drum.
