Description
Verfahren zum künstlichen Reifen von Zement mittels Preßluft, Preßgas o. dgl. Zusatz zum Patent 604 049 Gegenstand der Erfindung ist ein Verfahren zum künstlichen Reifen von Zement mittels Preßluft, Preßgas o. dgl. Das Wesentliche der Erfindung nach dem Hauptpatent 604049 besteht in einem Verfahren zum Auflockern von staubförmigem, in Behältern eingelagertem Gut mittels Preßgas, Preßluft o. dgl. Das Merkmal dieser Erfindung wird darin gesehen, daß das gasförmige Druckmittel in un-.endlich fein verteiltem Zustande in den Gutbehälter, Silo oder Bunker eingeblasen wird. Das Einblasen kann dabei beispielsweise an der Grundfläche des Gutbehälters erfolgen, der zu dem Zweck aus leicht luftdurchlässigem Baustoff, wie Filtersteinen o. dgl., hergestellt wird.Process for the artificial maturation of cement by means of compressed air, compressed gas o. The like. Addendum to patent 604 049 The invention relates to a method for artificial maturation of cement by means of compressed air, compressed gas or the like. The essentials the invention according to the main patent 604049 consists in a method for loosening of dusty goods stored in containers by means of compressed gas, compressed air or the like. The feature of this invention is seen in the fact that the gaseous pressure medium blown into the material container, silo or bunker in an infinitely finely divided state will. The blowing in can be done, for example, on the base of the material container made of slightly air-permeable building material such as filter stones for the purpose o. The like., is produced.
Versuche und Studienarbeiten haben nun ergeben, daß ein derartiges Verfahren mit besonderem Vorteil in der Zern:entindustrie anwendbar ist, um den frisch vermahlenen Zement künstlich zu altern oder zu reifen. Es ist an sich eine bekannte Tatsache, daß fast jeder frisch gemahlene Zement eine geringe Menge freien Kalk enthält und zwecks Ablöschung desselben erst längere Zeit, und zwar mehrere Monate, in geeigneten Silos o. dgl. ablagern muß, bevor er gebrauchsfertig ist. Man mußte den Zement während dieser Zeit der Einwirkung von Luft oder Kohlensäure aussetzen, und es war ein mehrfaches Umschaufeln oder Umfüllen erforderlich, um ihn mit der Luftfeuchtigkeit besser in Berührung zu bringen und zu durchlüften. Es liegt auf der Hand, daß ein derartiges künstliches Altern oder Reifen des Zements außerordentlich kostspielig ist, ganz abgesehen, davon, daß es auch in hohem Maße von der Temperatur der Luft, von der Luftfeuchtigkeit und anderen Momenten abhängt: Demgegenüber besteht die vorliegende Erfindung darin, daß das Gas in unendlich fein verteiltem Zustande durch Filtersteine oder ähnliche Arbeitsmittel in den im Gutbehälter befindlichen Zement eingeblasen wird. Dem im Behälter befindlichen Mehl wird auf der ganzen Bodenfläche dauernd oder periodisch je nach Bedarf das kohlensäurehaltige Gas zugesetzt; das Mehl wird auf diese Weise fließfähig gemacht und nach-vollendeter Reifung zum Ausfließen gebracht.Experiments and studies have now shown that such a thing Process with particular advantage in the Zern: entindustrie is applicable to the to artificially age or mature freshly ground cement. It is one in itself known fact that almost all freshly ground cement releases a small amount Lime contains lime and for the purpose of quenching it only for a long time, and indeed several times Months, in suitable silos or the like. Must be stored before it is ready for use. One had to use the cement during this period of exposure to air or carbonic acid exposing, and multiple shoveling or decanting was required to better bring it into contact with the humidity and to ventilate it. It is obvious that such artificial aging or ripening of the cement is extraordinarily costly, quite apart from the fact that it is also to a large extent depends on the temperature of the air, on the humidity and other moments: In contrast, the present invention is that the gas in infinitely fine distributed state through filter stones or similar work equipment in the material container the cement is blown in. The flour in the container will rise the whole area of the floor continuously or periodically, depending on the needs, the carbonated Gas added; the flour is made flowable and more finished in this way Ripened maturation brought to flow.
