Bei den bisher bekanntgewordenen Schlägermühlen für Mühlenfeuerungen fällt Mahlgut im Sinne der Drehrichtung des Schlägersystems in die Mühle ein. d. h. es erhält durch die Schläger eine Beschleunigung, während auf der dem Einfall entgegengesetzten Seite die Abführung des Mahlstaubes nach oben in den Sichter oder in die Brennkammer erfolgt. In the previously known beater mills for mill firing, grist falls into the mill in the sense of the direction of rotation of the beater system. d. H. it gets through the bat an acceleration while on the opposite side of the incidence the grinding dust is discharged upwards into the classifier or into the combustion chamber. to Die Erfindung besteht darin3 daß das Mahlgut in an sich bekannter Weise entgegen der Drehrichtung des Schlägersystems eingeführt wird, d. h. bei der es auf die aufsteigenden Schläger fällt und hierbei durch Prallwirkung zerkleinert wird. Grobstücke werden infolge der Fliehkraft an die Gehäusewand b ausgeschleudert, fallen von dort weiter zerkleinert wieder auf die Schläger und werden wiederum an die Wand c geschleudert. Durch diese laufend wechselnde Übernahme der Zerkleinerungsarbeit zwischen Schlägern und Prallwänden wird eine intensive Zerkleinerung des Mahlgutes erreicht. Bei den bisher bekanntgewordenen Prallschlägermühlen λνΐι-d der Mahlstaub durch ein am Boden der Schlägermühle befindliches Sieb nach unten ausgetragen.The invention consists in 3 that the ground material is introduced in a manner known per se against the direction of rotation of the racket system, ie in which it falls on the rising racket and is crushed by the impact effect. Coarse pieces are thrown against the housing wall b as a result of the centrifugal force, from there fall further on the racket and are again thrown against the wall c. This constantly changing takeover of the comminution work between the beater and the baffle walls results in an intensive comminution of the material to be ground. In the previously known impact beater mills λνΐι-d, the grinding dust is discharged downwards through a sieve located at the bottom of the beater mill. Erfindungsgemäß wird die beschriebene Zuführung des Mahlgutes durch den Schacht a entgegen der Schlägerbewegung bei Mühlen mit aufgesetztem Windsichter d angewendet, wobei die Abführung für den brennfertigen, in den Sichter zu führenden Staub auf der gleichen Mühlenseite wie die Zuführung angeordnet ist.According to the invention, the described feeding of the ground material through the shaft a is used against the hammer movement in mills with an attached air classifier d , the discharge for the ready-to-burn dust to be fed into the classifier being arranged on the same side of the mill as the feeder. Der Schieber e im Sichter dient der Regelung der Sichtung.The slide e in the classifier is used to regulate the classification. PΛ T E N T Λ K S P R U C II :PΛ T E N T Λ K S P R U C II: Sieblose Schlägermühle für Brennstaubfeuerungen, die dem Feuerraum unmittelbar vorgebaut ist, mit aufgesetzter Sichtkammer, dadurch gekennzeichnet, daß auf der Seite der Mühle, auf der die Bewegung der Schläger aufwärts gerichtet ist, der Zulauf für das entgegen der Schlägerumlaufrichtung aufzugebende Mahlgut und die Abführung für den brennfertigen, nach oben in den Sichter zu leitenden Staub angeordnet sind.Screenless beater mill for pulverized fuel combustion, which is directly connected to the combustion chamber is built in front, with attached viewing chamber, characterized in that on the side of the mill on which the movement of the hammer is directed upwards, the inlet for the counter to the direction of rotation of the hammer to be fed regrind and the discharge for the ready-to-burn, after are arranged at the top of the classifier to be conductive dust.
