Description

Verfahren zum Stückigmachen von Feinkohle Da die Verwendung von Feinkohle, insbesondere von Feinbraunkohle, beschränkt ist, wird sie vielfach unter Zusatz von Bindemitteln, oft auch bei erhöhter Temperatur, brikettiert. Die aufzuwendenden Produktionsmittel sind beträchtlich, so daß eine solche Anlage nur auf Stellen beschränkt bleibt, wo günstige Voraussetzungen, wie Größe -des Vorkommens, Nähe eines großen Absatzgebietes und wenn möglich der Anschluß an ein größeres Werk gegeben sind.Method of making fine coal lump Since the use of fine coal, in particular by fine lignite, it is often added of binding agents, often also at elevated temperature, briquetted. The to be expended Means of production are considerable, so that such a plant is limited to places remains where favorable conditions, such as size -of occurrence, proximity of a large one Sales area and, if possible, a connection to a larger plant.

Es wurde gefunden, daß man Feinkohle auch mit einfachen Hilfsmitteln zu größeren Stücken formen kann, so daß auch Feinkohle aus kleinen, ungünstig gelegenen Vorkommen aufgearbeitet werden kann.It has been found that fine coal can also be produced with simple tools Can shape into larger pieces, so that even fine coal from small, unfavorably located Occurrence can be worked up.

Wird nämlich feinste Kohle mit einigen Prozenten eines flüssigen Bindemittels versetzt, so kann sie in einer Trommel granuliert werden. Von besonderer Bedeutung ist die Wahl des Bindemittels, das zweckmäßig bei erhöhter Temperatur flüssig ist (Hartteer), bei welcher Temperatur dann das Granulieren erfolgt, während nachdem Abkühlen die einzelnen Eier hart sind. Selbstverständlich können auch andere organische Substanzen gewählt werden, die, wie konzentrierte Sulfitlauge, mit der Zeit oder besonders bei erhöhter Temperatur, z. B. beim Durchgang der Granalien durch einen Trockner, ähnlich wie Kunstharzsorten erhärten.It is made from the finest coal with a few percent of a liquid binder added, it can be granulated in a drum. Really important is the choice of the binder, which is expediently liquid at an elevated temperature (Hard tar), at which temperature the granulation then takes place, during after Cool down the individual eggs are hard. Of course, other organic ones can also be used Substances are chosen that, like concentrated sulphite liquor, with time or especially at elevated temperature, e.g. B. when the granules pass through one Dryer harden in a similar way to synthetic resin types.

Auch Emulsionen, wie sie für die Herstellung von Teer-Macadam-Straßen Verwendung finden, kommen in Betracht.Also emulsions like those used for making tar macadam roads Are used.

Die so hergestellten Granalien aus Feinkohle und Bindemitteln haben zumeist, in Anbetracht der geringen Reichweite der entsprechenden Vorkommen, genügende Festigkeit. Selbstverständlich ist es zweckmäßig, beim Granulieren alle Maßnahmen zu ergreifen, die die Festigkeit der hergestellten Granalien erhöhen; aus diesem Grunde wird man zweckmäßig die Trommel eine zusätzliche exzentrische Bewegung ausführen lassen.The granules made in this way from fine coal and binders have mostly, considering the small amount Range of the appropriate Occurrence, sufficient strength. Of course, it is useful when granulating to take all measures that increase the strength of the granules produced; For this reason, the drum is expediently an additional eccentric one Let movement be carried out.
