Description

Ring- oder ähnliche 1Vlühle mit einer Luftförderung im 1Vlühlenraum und einer mechanischen Fördervorrichtung, welche das vom Feinen geschiedene Grobe den Mahlflächen zur Weitervermahlung wieder zuführt Zusatz zum Patent 4:8o 8o9*) Die Erfindung betrifft eine Verbesserung der an einer durch Patent 4.80 809 geschützten Fördervorrichtung. Auf der Zeichnung ist in Abb. i ein Längsschnitt durch die Mitte dargestellt, aus dem die im Gehäuse angeordnete Fördervorrichtung zu erkennen ist. Abb. 2 ist ein Schnitt durch die Fördervorrichtung nach der Linie A-ß der Abb. i.Ring or similar 1Vlühle with air conveyance in the 1Vlühlenraum and a mechanical conveying device, which feeds the coarse separated from the fines to the grinding surfaces for further grinding Addition to patent 4: 8o 8o9 *) The invention relates to an improvement of the conveying device protected by patent 4.80 809 . In the drawing, Fig. I shows a longitudinal section through the center, from which the conveyor device arranged in the housing can be seen. Fig. 2 is a section through the conveyor device along the line A-ß of Fig. I.

Zur besseren Aufteilung des von den Bechern :2 aufzuschaufelnden Gutes ist die Fördervorrichtung in an sich bekannter Weise mit Räumern 3 versehen worden, die den Zweck haben, das auf dem unteren lichten Gehäuseumfang liegende, noch nicht genü= gend gefeinte Gut umzuschichten und hochzuheben. Das Hochheben des Gutes ist durch den Ausschüttwinkel der Räumer, auf denen das Gut liegt, begrenzt. Für die günstigste Ausschüttung ist die Stellung der Räumer 3 so zu wählen, daß das Gut schleierartig dem auf einen großen Teil des. Mahl.ringumfanges herumgeführten Luftstrom entgegenrieselt und das vom Winde dann nicht abgeschiedene grobe Gut sodann in die Becher fällt.For a better division of the items to be scooped up from the cups: 2 the conveyor device has been provided with scrapers 3 in a manner known per se, the purpose of which is not yet what lies on the lower clear housing circumference To rearrange and lift up enough fine goods. The lifting of the good is limited by the angle of discharge of the scraper on which the property lies. For the cheapest distribution is the position of the scraper 3 to choose so that the good like a veil to the air flow guided around a large part of the circumference of the grinding ring trickles towards and the coarse material not separated by the wind then into the Cup falls.

Durch diese Anordnung ergibt sich fast eine restlose Sichtung des Gutes. Für den j Luftstrom sind im Ringraum noch Jalousien 6 und Führungsbleche 7 angeordnet. Vom Luftstrom mitgerissene gröbere Teilchen stoßen an Flächen B. Infolge der verminderten Luftgeschwindigkeiten an den Stellen 8 werden sie dann ausgeschieden und gleiten an der Wand 9 herunter.This arrangement results in an almost complete sighting of the Good. There are also blinds 6 and guide plates in the annulus for the air flow 7 arranged. Coarser particles carried along by the air flow hit surfaces B. As a result the reduced air velocities at the points 8, they are then excreted and slide down the wall 9.

Des leichteren Auswechselns wegen besteht die Fördervorrichtung aus einem im Querschnitt winklig geformten Ringe i, um den eine Kette i i gelegt ist, die mit dem Ring verbunden ist und mit einem Kettenrad in Eingriff steht.To make it easier to change, the conveying device consists of a ring i with an angular cross-section around which a chain i i is placed, which is connected to the ring and meshes with a sprocket.
