Description
Gegenstand der Erfindung ist eine kombinierte Schleuderkugelmühle, bei der zwei Mahlkammern hintereinandergeschaltet sind. In der ersten Kammer wird das Mahlgut durch eine Schleudermühle feingeschrotet, während in der zweiten Kammer das dieser zugeleitete Gut durch kleine Mahlkörper feingemahlen wird. Gemäß der Erfindung ist der Mantel der den schnell laufenden Schlagrotor umgebenden Mahltrommel siebartig durchbrochen und mit Abstand von einer geschlossenen Trommel konzentrisch umgeben, in .der kleine Mahlkörper zur Feinmahlung vorgesehen sind. Durch diese Bauart wird gegenüber bekannten Mühlen, bei denen die Trommelmühle axial hinter der Schlägermühle angeordnet ist, der Vorteil eines günstigeren Wirkungsgrades. und einer größeren Raumersparnis erzielt.The invention relates to a combined centrifugal ball mill, in which two grinding chambers are connected in series. In the first chamber will the grist is finely ground through a centrifugal mill while in the second chamber that this supplied material is finely ground by small grinding media. According to the The invention is the jacket of the grinding drum surrounding the high-speed beater rotor perforated like a sieve and concentric at a distance from a closed drum surrounded, in .the small grinding media are provided for fine grinding. Through this The design is opposite to known mills in which the drum mill is axially behind the beater mill is arranged, the advantage of a more favorable efficiency. and a greater space saving achieved.
Die Zeichnung veranschaulicht ,die Erfindung in einigen Ausführungsbeispielen in schematischer Darstellung.The drawing illustrates the invention in some exemplary embodiments in a schematic representation.
Durch das Einfüllrohr i wird das Mahlgut von der Stirnseite der langsam rotierenden Trommel :2 aus in diese eingeführt. Der Mantel der Trommel ist siebartig durchbrochen und gegebenenfalls mit nach innen vorstehenden Hubleisten 3 besetzt, durch welche das Mahlgut fortlaufend auf den mit seiner Welle io konzentrisch zur Trommel in :den Lagern i i gelagerten, schnell umlaufenden, mit Schlagleisten 5 besetzten Rotor 4 ,geworfen wird, wodurch eine entsprechende Zerkleinerung stattfindet. Das genügend zerkleinerte Gut fällt durch die Öffnungen des durchbrochenen Mantels der Drehtrommel 2 in die :damit verbundene, mit Ab- stand konzentrisch um die Trommel 2 angeordnete Trommel 6, in welcher die Feinzerkleinerung durch Mahlkörper 7 erfolgt. Aus der Trommel 6 gelangt das fertige Gut bei der in den Abb. i und :2 gezeigten Bauart durch Schlitze 8 in das feststehende Austraggehäuse 9. Die Trommel 6 kann in bekannter Weise auf Rollen gelagert sein und beliebigen Antrieb erhalten.The ground material is introduced into the slowly rotating drum: 2 through the filling pipe i. The shell of the drum is perforated like a sieve and optionally occupied with inwardly protruding lifting strips 3, through which the ground material is continuously thrown onto the rapidly rotating rotor 4 fitted with blow bars 5 with its shaft concentrically to the drum in: the bearings ii whereby a corresponding comminution takes place. The sufficiently comminuted material falls through the openings of the perforated shell of the rotary drum 2 in the: associated stood with waste concentrically around the drum 2 arranged drum 6, in which the comminution is carried out by grinding media. 7 In the design shown in FIGS. 1 and 2, the finished product passes from the drum 6 through slots 8 into the stationary discharge housing 9. The drum 6 can be mounted on rollers in a known manner and can be provided with any drive.
Der Raum zwischen den Trommeln 2 und 6 kann, wie die Abb. 3 erkennen läßt, durch Wände 15 in einzelne Kammern 16 unterteilt sein, in denen Mahlkörper 7 .die Feinmahlarbeit leisten: In Abb. 4 ist die Trommel 6 von Bandagen 19 umgebene und mit .diesen auf einer angetriebenen Laufrolle 2o gelagert. Die Trommel ist an ihrem rechten Ende 2,1, eingezogen und mit dem Flansch 22 gegen das feststehende Austraggehäuse 9 abgedichtet. Eine mit ,der Welle %io umlaufende Siebsche-ibe 23 hält das gröbere Gut zurück, während das feine in das Austraggehäuse 9 übertritt. In dem konischen Teil-2i sammeln sich vorzugsweise die kleineren Mahlkörper; welche die zusätzliche Feinzerkleinerung bewirken. Das .genügend gefeinte Gut wird aus dem Austraggehäuse abgesaugt und gelangt durch ein Rohr 26 in den S.ichter 27, aus dem das grobe Gut durch die Rohrleitung 28 im Kreislauf in die Mühle zurückgeführt und das genügend gefeinte durch die Schnecke 29 abgeleitet wird.The space between the drums 2 and 6 can be seen in Fig. 3 can be divided by walls 15 into individual chambers 16 in which grinding media 7. Do the fine grinding work: In Fig. 4 the drum 6 is surrounded by bandages 19 and with .these mounted on a driven roller 2o. The drum is on its right end 2.1, retracted and with the flange 22 against the stationary Discharge housing 9 sealed. A sieve disk 23 rotating with the shaft% io holds back the coarser material, while the fine material passes into the discharge housing 9. The smaller grinding media are preferably collected in the conical part-2i; Which cause additional fine grinding. The .sufficiently refined good becomes out the discharge housing and passes through a pipe 26 into the sifter 27 which the coarse material is returned to the mill through the pipeline 28 in a circuit and that which is sufficiently fine is diverted by the screw 29.
