Description

Verfahren zur Behandlung von ungebrannten und gebrannten Düngekalken mit Torf Die Erfindung betrifft eine weitere Ausbildung des im Hauptpatent 927 994 unter Schutz gestellten Verfahrens zur Behandlung von ungebrannten und gebrannten Düngekalken mit Torf.Process for the treatment of unburned and burnt manure limes with peat The invention relates to a further development of the main patent 927 994 Protected process for the treatment of unfired and burned Lime fertilizer with peat.

Bei dem Verfahren nach dem Hauptpatent wird vorgeschlagen, gebrannte oder ungebrannte Kalke, wie sie üblicherweise für Düngezwecke verwendet werden, mit Torf zu behandeln.In the case of the method according to the main patent, it is proposed to use fired or unburnt limes, as they are usually used for fertilization purposes, treat with peat.

Die weitere Ausbildung dieses Verfahrens besteht darin, daß als Ausgangsstoff die bei :der Verhüttung von Eisenerzen mit Kalkzuschlägen anfallenden Hochofenschlacken (Hüttenkalk) verwendet werden.The further development of this process consists in that as a starting material the blast furnace slag resulting from: the smelting of iron ores with lime aggregates (Hüttenkalk) can be used.

Bei der Durchführung .dieses verbesserten Verfahrens wird die Hochofenschlacke (Hüttenkalk) mit Torf, vorzugsweise mit Weißtorf, in Gewichtsteilen von 3o bis 55 auf je iooo Gewichtsteile Hochofenschlacke behandelt.When this improved process is carried out, the blast furnace slag (Hüttenkalk) with peat, preferably with white peat, in parts by weight from 3o to 55 treated for every thousand parts by weight of blast furnace slag.

Die beiden Bestandteile Hochofenschlacke und Weißtorf können genau so wie bei dem Verfahren nach dem Hauptpatent 927 994 für sich gemahlen und in den vorstehend angegebenen Gewichtsteilen miteinander vermischt werden.The two components blast furnace slag and white peat can be used precisely as in the method according to the main patent 927 994 ground for itself and in the parts by weight given above are mixed together.

Im folgenden wird ein Ausführungsheispiel beschrieben, bei dem Weißtorf mit 48 bis 5o% Wassergehalt verwendet wird.In the following an exemplary embodiment is described in which white peat with 48 to 5o% water content is used.

Zu iooo Gewichtsteilen Hochofenschlacke (Hüttenkalk) werden etwa 55 Gewichtsteile zerfaserter Weißtorf beigegeben und das Gemisch miteinander vermahlen. Der wesentliche Vorteil des Verfahrens der Erfindung besteht in folgendem: Wenn Hochofenschlacke als Düngemittel (Hüttenkalk) verwendet werden soll, so muß sie äußerst fein vermahlen werden, damit ihre .düngenden Eigenschaften im Boden zur Wirkung kommen. Diese feinst vermahlene Hochofenschlacke läßt sich jedoch nur in dichten Säcken; wozu heutzutage Papiersäcke üblich sind, verladen und transportieren. Der Hüttenkalk ist wegen seiner äußerst feinen, Vermahlung noch schwieriger zu verladen und zu verschicken als .die weniger fein vermahlenen, sonst für die Düngung üblichen und bekannten Düngekalke.For 1,000 parts by weight of blast furnace slag (metallurgical lime), about 55 Parts by weight of fiberized white peat are added and the mixture is ground together. Of the The main advantage of the method of the invention consists in the following: When blast furnace slag is to be used as fertilizer (cottage lime), it must be ground extremely finely so that their fertilizing properties can take effect in the soil. This finest However, ground blast furnace slag can only be stored in tight bags; what for now Paper bags are common to be loaded and transported. The Hüttenkalk is because of it extremely fine, grinding even more difficult to load and dispatch than .the less finely ground, otherwise common and well-known fertilizer limes for fertilization.

Durch das Verfahren der Erfindung aber, bei welchem diese äußerst fein vermahlene Hochofenschlacke mit Torf in der vorgeschlagenen Weise behandelt wird, läßt sich dieses Düngemittel nunmehr in Kallcdeckelwagen lose verladen, verschicken und auch leicht aus diesem Wagen durch Ausschaufeln entladen.By the method of the invention, however, in which this extremely finely ground blast furnace slag treated with peat in the manner proposed this fertilizer can now be loosely loaded and shipped in Kallcdeckelwagen and also easily unloaded from this car by shoveling.
