Auf den Anthrazitkohle fördernden Gruben fallen in vergleichsweise großen anteiligen Mengen — auf die Gesamtförderung bezogen — Anthrazitschlärnme und Anthrazitstäube an, die nicht für sich verbrannt werden können und deshalb ein verhältnismäßig geringwertiges Brennmaterial darstellen, das lediglich in verhältnismäßig geringen anteiligen Mengen der Kesselkohle beigemischt werden kann.On the pits producing anthracite coal there are comparatively large proportions related to the total funding - anthracite slurpings and anthracite dusts that did not burn for themselves can be and therefore represent a relatively low-quality fuel that is only can be added to the steam coal in relatively small proportions.
Die wirtschaftliche Verwertung der insgesamt anfallenden Mengen dieses Feinmaterials stößt deshalb auf erhebliche Schwierigkeiten. Es fehlte daher nicht an Versuchen, andere Verwendungsmöglichkeiten für dieses sonst Abfall darstellende Material zu finden. Eine der vorteilhaftesten Möglichkeiten hierfür, die mit gutem Erfolg in die Praxis umgesetzt werden konnte, ist die Verarbeitung der Anthrazitstaub- und -schlammkohle nach besonderen Verfahren zu hochwertigem Brennstaub für Kohlenstaubfeuerungen.The economic recovery of the total amount of this fine material is therefore a problem to significant difficulties. There was therefore no lack of attempts to find other possible uses for to find this otherwise garbage material. One of the most beneficial ways to do this is the The processing of the anthracite dust and -sludge coal using a special process to produce high-quality fuel dust for pulverized coal firing.
Eine weitere wesentliche der bekannten Verwengungsmöglichkeiten von Anthrazitstaub, die erst in neuerer Zeit erkannt wurde, ist die als Füllstoff für Kautschukmischungen an Stelle der üblichen inerten Füllstoffe, wie Kaolin, Betonit, Quarz- oder Kalkstaub u. dgl.Another essential of the known contraction possibilities of anthracite dust, which only appeared in It has recently been recognized that it is used as a filler for rubber mixtures instead of the usual inert ones Fillers such as kaolin, bentonite, quartz or lime dust and the like.
Für diesen Zweck eignet sich Anthrazitstaub an sich vorzüglich, jedoch sind bisher seiner Verwendungsmöglichkeit hierfür Grenzen durch die Forderungen, die an die Eigenschaften der herzustellenden Hart- oder Weichkautschukkörper vom Gesichtspunkt ihrer verschiedenen Verwendungszwecke zu stellen sind, wie insbesondere deren Dichte, Homogenität, Dielektrizitätskonstante, Porosität und allgemeinen Festigkeitseigenschaften, gezogen.Anthracite dust is ideally suited for this purpose, but it has been possible to use it so far this is limited by the demands placed on the properties of the products to be manufactured Hard or soft rubber bodies from the point of view of their various uses are, in particular their density, homogeneity, dielectric constant, porosity and general Strength properties, drawn.
Es liegt nahe, die Forderung nach Homogenität der Fertigerzeugnisse dadurch zu erfüllen, daß der Anthrazitstaub in einer besonders feinen Korngröße verwendet wird.It makes sense to meet the requirement for the homogeneity of the finished products in that the Anthracite dust is used in a particularly fine grain size.
Diese Möglichkeit scheitert aber daran, daß die Klassierung des Feinguts in die Korngrößenbereiche von 0 bis etwa 30 μ und über 30 μ. zwangläufig eine von 0 bis etwa 30 μ und über 30 μ zwangläufig eine vorherige Trocknung des Ausgangsmaterials (Schlämme und Staub) bedingt.This possibility fails, however, because the classification of the fine material into the grain size ranges from 0 to about 30 μ and over 30 μ. inevitably one from 0 to about 30 μ and over 30 μ inevitably The raw material (sludge and dust) must be dried beforehand.
Gegenstand der Erfindung ist ein Aufbereitungsverfahren, welches es ermöglicht, aus dem auf einer Zeche anfallenden Anthrazitfeingut, und zwar auch den feinsten Fraktionen derselben, ein den bisher daraus gewonnenen Füllstoffen für Hart- oder Weichkautschuk überlegenes Füllstoffmaterial von immer gleichbleibenden Eigenschaften herzustellen, das in hohen prozentualen Anteilen zugesetzt werden kann und dessen Verwendung sich insbesondere wegen Verfahren zur AufbereitungThe invention relates to a processing method which makes it possible from the on a Colliery anthracite fine goods, including the finest fractions of the same, one of the ones so far The fillers obtained from it for hard or soft rubber have always been superior filler materials produce consistent properties, which can be added in high percentages and its use in particular because of processing methods

seines im Vergleich zu den bisher verwendeten Füllstoffen außerordentlich niedrigen spezifischen Gewichts, der günstigen Beeinflussung der Elektrizitätskonstante, ferner der mechanischen Eigenschaften, wie der Schlag- und Kerbfähigkeit der Endprodukte, in einer erheblichen Verbesserung des Fertigproduktes auswirkt, wobei die bei diesem Verfahren außer dem für diese Zwecke verwendeten Feinstgutanteil anfallende Fraktion von über 30 μ Korngröße ein Material von derart gesteigerter Qualität darstellt. Hierdurch werden die Mehrkosten, die durch die Behandlungsmaßnahmen des Ausgangsgutes verursacht werden, bei weitem ausgeglichen.its extremely low specific weight compared to the previously used fillers, the favorable influence of the electricity constant, furthermore the mechanical properties, like the impact and notch ability of the end products, in a considerable improvement of the finished product affects, with this process except for the fine material used for these purposes The resulting fraction of over 30 μ grain size represents a material of such increased quality. This eliminates the additional costs caused by the treatment measures for the original material be balanced by far.
Das erfindungsgemäße Verfahren besteht darin, daß der sein Ausgangsmaterial bildende Anthrazitkohlenstaub oder -schlamm von maximal 2 mm Korngröße einer Trocknung bei Temperaturen von höchstens 300° C und einer nachfolgenden Prallzerkleinerung auf eine Korngröße von etwa 70 μ unter Aufrechterhaltung bzw. Freilegung der Strukturflächen der Teilchen unterworfen und anschließend durch eine Klassierung bei einer Kornscheide von etwa 30 μ in eine aschereichere Feinstgutfraktion und eine gegenüber dem Ausgangsmaterial hochwertigere ascheärmere gröbere Fraktion zerlegt wird.The method according to the invention consists in that the anthracite coal dust forming its starting material or sludge with a maximum grain size of 2 mm drying at temperatures of at most 300 ° C and a subsequent impact crushing to a grain size of about 70 μ while maintaining or exposure of the structural surfaces of the particles subjected and then through a classification with a grain size of about 30 μ into an ash-rich fine material fraction and a Compared to the starting material, a higher quality, lower-ash, coarser fraction is broken down.
Durch diese Art der Trocknungsbehandlung bei Temperaturen von höchstens 300° C, zweckmäßig noch darunter von unterhalb 250° C, wird sichergestellt, daß auf keinen Fall Verkokungserscheinungen beginnen und auch die leichtflüchtigen Bestandteile, die in dem Ausgangsmaterial erhalten sind, insbesondere der Wasserstoff, erhalten bleiben. Diese Trocknung wird unter Bedingungen durchgeführt, die es ausschließen, daß das Material irgendwie mit Rauchgasen bzw. Koksbestandteilen in Kon-This type of drying treatment at temperatures of at most 300 ° C. makes it expedient even below 250.degree. C., it is ensured that there is no coking phenomenon begin and also the volatile components that get in the starting material are, in particular the hydrogen, are retained. This drying is carried out under conditions which rule out that the material somehow comes into contact with flue gases or coke constituents.
