Die Erfindung betrifft eine besonders für Kohlenstaubfeuerungen bestimmte Schlagmühle, die in bekannter Weise mit einem Heizmantel versehen ist. Das Neue besteht darin, daß Zusatzluft in erhitztem Zustande durch die Heizräume und aus diesen in regelbaren Mengen in das Mühleninnere geleitet wird.
Eine Mühle mit dieser neuen EinrichtungThe invention relates to a hammer mill which is particularly intended for pulverized coal combustion and which is provided in a known manner with a heating jacket. The novelty is that additional air in a heated state is passed through the boiler rooms and from these in controllable quantities into the mill interior.
A mill with this new facility

It allows you to do without one with such coal

Insbesondere hat die Zufuhr dieser heißen Luft, die durch die vorherige Benutzung in denis special drying system because the additional heated air it is already enough to remove the excess moisture content. In particular has the supply of this hot air, which by previous use in the

ao Heizräumen bereits so weit abgekühlt ist, daß sie keine Entzündungsgefahr mehr darstellt, den Vorteil, daß sie den zu verfeuernden Staub, der sonst leicht zusammenbackt, trocknet und dadurch in Staubform erhält.ao boiler rooms have already cooled down enough that they no longer pose a risk of ignition, the advantage that they remove the dust to be burned, which otherwise cakes easily, dries and thus retains it in the form of dust.

»5 In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt.»5 In the drawing, the invention is in an embodiment shown.

Auf einer Welle ι sind in bekannter Weise die Schläger 2 angeordnet, die in Schlagkammern 3 laufen. Die Schlagkammern 3 sind derart in dem Gehäuse 4 untergebracht, daß zwischen dem Gehäuse und den Schlagkammern ein ringförmiger Hohlraum 5 bleibt. In diesem wird durch einen Stutzen 6 Heißluft eingeführt, die beispielsweise aus dem den Zündkopf umgebenden Mantel herstammt. Nachdem die Heißluft die Räume 5 durchstrichen hat, gelangt sie durch regelbare öffnungen 7 in das Innere der Trommel, und zwar je nach Bedarf in den verschiedenen Fällen in verschiedenen Mengen. Die Luft entzieht damit der Kohle noch weiterhin Feuchtigkeit und erwärmt sie gleichzeitig, so daß sie bereits in angewärmtem Zustande in den Feuerraum gelangt und demzufolge auch leichter entzündet wird.On a shaft ι the rackets 2 are arranged in a known manner, which are in impact chambers 3 run. The impact chambers 3 are housed in the housing 4 that between the housing and the Impact chambers an annular cavity 5 remains. In this one is Nozzle 6 hot air introduced, for example from the area surrounding the ignition head Coat. After the hot air has passed through the rooms 5, it arrives through adjustable openings 7 in the interior of the drum, depending on requirements in the different cases in different amounts. This removes the air from the coal still continues to moisture and warms them at the same time, so that they are already warmed in State enters the furnace and is therefore more easily ignited.
