Description

Das Absaugen des feinen Staubes macht bei den bis jetzt bekannten schnellaufenden Schlägermühlen besondere Schwierigkeiten, da die Sichtungsluft nicht so geführt wird, daß sie sofort nach der Entstehung des feinen Staubes denselben von den gröberen Teilen abtrennt und weiterfördert. Die gemäß der Erfindung ausgebildete Schlägermühle soll diesen Übelstand beseitigen.The suction of the fine dust makes the high-speed ones known up to now Beater mills have particular difficulties, as the sifting air is not guided in such a way that they immediately after the formation of the fine dust the same from the coarser parts separates and further promotes. The beater mill designed according to the invention is intended to eliminate this drawback.

ίο Wie die Zeichnung erkennen läßt, ist gemäß der Erfindung der Mahlmantel einer schnellaufenden Schlagkreuzmühle mit Schlitzen h versehen. Durch diese Schlitze h strömt Luft in das Innere der Mühle. Bei dem Durchtritt der Luft durch das infolge der Zentrifugalkraft nach außen geschleuderte Mahlgut werden die leichteren Teilchen mitgerissen und durch den Ventilator / weiter^ befördert. Durch Änderung der Luftaustrittsgeschwindigkeit aus den Schlitzen h hat man es in der Hand, das Mahlgut bis zu einer bestimmten Korngröße abzusaugen, was besonders beim Vermählen von Kohle für Staubfeuerung von großer Wichtigkeit ist.As the drawing shows, according to the invention, the grinding jacket of a high-speed cross beater mill is provided with slots h. Air flows into the interior of the mill through these slots h. When the air passes through the grist, which is thrown outwards by the centrifugal force, the lighter particles are carried away and transported by the fan. By changing the air outlet speed from the slots h you have the ability to suck off the ground material up to a certain grain size, which is of great importance especially when grinding coal for dust firing.

as Das Mahlgut ist bei α in die Mühle gegeben und wird zunächst dem Verteilkegel b zugeführt. Infolge der schnellen Umdrehung dieses mit der Mühlenwelle sich drehenden Kegels wird das Gut durch die Öffnungen c in der Kegelwandung nach außen, also zwisehen die Schläger geschleudert. Das abgesichtete Gut wird durch Auslaß g nach einem Vorratsbehälter oder nach der Feuerungsstelle geführt, diejenigen Gutteilchen; die etwa durch die Luftschlitze h hindurchgefallen sind, werden in einer die Mühle umgebenden beweglichen Trommel /, die auch' die Ansaugöffnung d für die Luft enthält, gesammelt und mit Hilfe eingebauter Rückführvorrichtungen k wieder in die Mühle zu-< rückgeleitet.The ground material is put into the mill at α and is first fed to the distribution cone b. As a result of the rapid rotation of this cone, which rotates with the mill shaft, the material is thrown outwards through the openings c in the cone wall, i.e. between the beater. The separated material is passed through outlet g to a storage container or to the furnace, those material particles; Anything that has fallen through the air slots h is collected in a movable drum surrounding the mill, which also contains the intake opening d for the air, and is returned to the mill with the aid of built-in return devices k.

Außer den oben schon genannten weist die neue Bauart noch den Vorteil auf, daß infolge des sofort nach dem Entstehen bewirkten Fortschaffens des Feinstaubes der Kraftverbrauch für die Mühle geringer ist. als wenn der feine Staub, sofern er nicht frühzeitig ausgeschieden wird, die Mahlgutmasse vermehrt und dabei hemmend wirkt.In addition to the ones already mentioned above, the new design also has the advantage that as a result of the removal of fine dust from the Power consumption for the mill is lower. as if the fine dust, if it was not is excreted early, the grist increases and has an inhibiting effect.
