Description

Bei Schlägermühlen ist es bekannt, die gesamte durch einen Kanal zugeführte Luft an einer Stelle von oben an die Schlägermühle heranzuführen. Da die große Drehzahl der Schlägermühle die Luft von innen nach außen schleudert, so· wird der seitlich zugeführten Luft ein gewisser Widerstand 'entgegengesetzt, der durch, erhöhte Windpressung überwunden werden muß. Um nun die zugeführte Luft leichter in -die Mühle hineinzubringen, wird nach der Erfindung der Luftstrom in zwei oder mehrere Teilströme geteilt, die je für sich an hintereinanderliegenden Stellen des Mühlenumfanges tangential zugeführt werden.In the case of beater mills, it is known to supply all of the air supplied through a duct at one point from above to the beater mill. Since the high speed of the The beater mill flings the air from the inside outwards, so · the side fed Air a certain resistance 'opposed to that overcome by increased wind pressure must become. In order to bring the supplied air into the mill more easily, is According to the invention, the air flow is divided into two or more partial flows, each for are fed tangentially at successive points on the mill circumference.

Dadurch ist es möglich, die Teilströme entsprechend klein zu haltern und die Zuführung durch düsenartige Mündungen so zu gestalten, daß die Luft in der Bewegungsrichtung der Schläger zugeführt, also von diesen mitgerissen wird.This makes it possible to keep the partial flows correspondingly small and the feed by nozzle-like mouths so that the air in the direction of movement the bat is fed, so it is carried away by them.

In der Zeichnung ist eine Mühle nach der Erfindung mit einer in zwei Ströme unterteilten Luftzuführung in senkrechtem Querschnitt dargestellt. Der durch den Luftkanal c zugeführte Luftstrom wird durch ieine von. außen verstellbare Klappe e in zwei Luftströme c' und c" geteilt, von denen der obere Luftstrom c' unmittelbar und tangential der Schlägermühle« zugeführt wird, während der untere Luftstrom c" durch einen Kanal / dem unteren Teil der Mühle zugeleitet wird.In the drawing, a mill according to the invention with an air supply divided into two streams is shown in vertical cross section. The air flow supplied through the air duct c is passed through one of. externally adjustable flap e divided into two air streams c ' and c " , of which the upper air stream c' is fed directly and tangentially to the beater mill«, while the lower air stream c " is fed through a duct / the lower part of the mill.

Man kann auch mehrere Teilströme vorsehen, denen Mündungen dann nacheinander am Umfang des abwärts laufenden Teiles der Schlägermühle liegen.You can also provide several partial flows, which then open out one after the other lie on the circumference of the downward running part of the beater mill.

Dadurch, daß der Luftstrom c" dem Boden der Mühle zugeführt wird, kann !man auch noch erreichen, daß der sich dort ansammelnde Kohlenstaub dauernd entfernt wird, dort also nicht durch Anhäufung störend wirkt.Because the air stream c "is fed to the bottom of the mill, it is also possible to ensure that the coal dust that collects there is permanently removed, so that it does not have a disruptive effect there by accumulation.
