Description
Die Erfindung betrifft eine Trommelsiebmaschine mit wenigstens einer rotierenden Siebtrommel, einem Einlauftrichter, einem Antrieb und wenigstens einer Sammel- bzw. Abtransportvorrichtung zum Abtransport des gesiebten Gutes.The invention relates to a drum screening machine with at least one rotating screen drum, an inlet funnel, a drive and at least one collecting or removal device for the removal of the screened material.
Trommelsiebmaschinen sind bekannt. Sie werden beispielsweise in Aufbereitungs- und Sortieranlagen zur Trennung von Materialien unterschiedlicher Größe bzw. Körnung eingesetzt. Sie bieten insgesamt ein breites Anwendungsspektrum, beispielsweise bei der Absiebung und Klassifizierung von Kompost, in der Restmüllaufbereitung, zum Deponierückbau, Absieben von Rindenmulch, geshreddertem Material, Altholzschnitt, Baumschnitt, Baumischabfällen, Bauschutt, Schlacken, Kies, Erden oder dergleichen.Drum screening machines are known. They are used for example in processing and sorting plants for the separation of materials of different sizes or grain size. Overall, they offer a wide range of applications, for example in the screening and classification of compost, in the processing of residual waste, for landfill dismantling, screening of bark mulch, shredded material, waste wood cut, pruning, tree waste, construction waste, slags, gravel, soils or the like.
Bei den bisher bekannten Trommelsiebanlagen ist es als Nachteil zu bewerten, dass als gesiebtes Gut nur das durch die Größe der Öffnungen in der Siebtrommel bestimmte Gut in seiner Körnung definiert ist. Das gesiebte Gut, welches in Transportrichtung des zu siebenden Gutes am Ende der Siebtrommel aus dieser ausgefördert wird, weist im Durchschnitt noch größere Mengen an Überkom auf, so dass dieses Gut noch einmal gesiebt werden oder insgesamt nochmals in eine Zerkleinerungsanlage gegeben werden muss, um es in einer bestimmten definierten Körnung zu erhalten.In the previously known Trommelsiebanlagen it is to be assessed as a disadvantage that is defined as sieved Good only determined by the size of the openings in the sieve drum Good in its grain size. The sieved material, which is conveyed in the transport direction of the material to be screened at the end of the screen drum from this, has on average even larger amounts of Überkom, so that this Good are sieved again or must be given in total again in a crushing plant to it to get in a certain defined grain size.
So haben die am Ende aus der Siebtrommel austretenden Materialien Körnungen, die zu etwa 90 Prozent einer bestimmten definierten Größe zuzuordnen sind. Etwa 10 Prozent dieses Gutes fallen jedoch als Überkorn dazu an, so dass ein nochmaliges Sieben oder das Zuführen des gesamten Gutes dieser Fraktion in eine Zerkleinerungsanlage notwendig ist. Dieses Problem tritt auch auf, wenn Steingitter am Einlauftrichter das Eintreten von bestimmten Übergrößen verhindern. Dabei entstehen höhere Aufwendungen an Arbeitszeit und Energie, die auch dazu führen können, das die bekannten Trommelsiebmaschinen lediglich in der Vorsortierung Einsatz finden oder nur beim Sieben solchen Gutes eingesetzt werden, bei dem die zuvor beschriebenen Abweichungen in der Körnung prozentual vernachlässigbar klein sind.For example, the materials leaving the screening drum at the end have grains that can be assigned to about 90 percent of a certain defined size. However, about 10 percent of this good as an oversize grain to, so that a repeated sieving or supplying the entire good of this faction in a crushing plant is necessary. This problem also occurs when stone meshes at the inlet funnel prevent the occurrence of certain sizes. This results in higher labor costs and energy, which can also cause the known Trommelsiebmaschinen be used only in the pre-sorting or only be used in the screening of such good, in which the previously described deviations in grain size are negligible percentage.
Insbesondere tritt dieses Problem beispielsweise bei mittels Walzen - Zerkleinerer oder Shredder zerkleinerten Bäumen aus Rodungen, Altholz, Eisenbahnschwellen oder dergleichen auf. Aber auch in der Restmüllverwertung ist dieses Problem relevant.In particular, this problem occurs, for example, in trees shredded by means of roller shredders or shredders from deforestation, waste wood, railway sleepers or the like. But also in the residual waste utilization this problem is relevant.
Aus der Druckschrift
Ausgehend von dem oben bekannten Stand der Technik ist es Aufgabe der Erfindung eine Trommelsiebmaschine zur Verfügung zu stellen, welche die oben beschriebenen Nachteile nicht mehr aufweist.Based on the above-known prior art, it is an object of the invention to provide a trommel screen available, which no longer has the disadvantages described above.
Die Aufgabe der Erfindung wird gelöst durch eine Trommelsiebmaschine, bestehend aus wenigstens einer rotierenden Siebtrommel wenigstens einem Antrieb für die Siebtrommel, einem Einlauftrichter, wenigstens einem Scheibensieb sowie wenigstens einer Sammel- bzw. Abtransportvorrichtung zum Sammeln bzw. Abtransport des gesiebten Gutes, die sich dadurch auszeichnet, dass das Scheibensieb auf dem Einlauftrichter der Trommelsiebmaschine angeordnet ist, uns das Scheibensieb ein definiertes Korn, insbesondere ein Überkorn absiebt. Durch die Anordnung eines Scheibensiebes auf dem Einlauftrichter der Trommelsiebmaschine wird das aus der Siebtrommel am Ende der Trommel austretende Gut als gesiebtes Gut in einer definierten Körnung bestimmt. Die Durchlassweite des Scheibensiebes definiert in ausreichender Genauigkeit jetzt die größte Körnung des zu mischenden Gutes.The object of the invention is achieved by a drum screening machine comprising at least one rotating screen drum at least one drive for the screen drum, an inlet funnel, at least one screen screen and at least one collecting or removal device for collecting or removal of the screened material, which is characterized in that the disc screen is arranged on the inlet funnel of the drum screen, the disc screen screens off a defined grain, in particular an oversize grain. By arranging a disc screen on the inlet funnel of Trommelsiebmaschine the emerging from the screen drum at the end of the drum Good is determined as sieved Good in a defined grain size. The passage width of the Scheibensiebes defined in sufficient accuracy now the largest grain size of the material to be mixed.
Bei einer Trommelsiebmaschine erhält man automatisch eine weitere, als definiert zu betrachtende, gesiebte Fraktion, die am Ende der Siebtrommel aus dieser austritt. Das Durchtreten des Überkorns wird durch das Scheibensieb nicht mehr zugelassen, wie dies beispielsweise bei den bisher bekannten Steingittem noch der Fall ist. Die Erfindung stellt danach eine Trommeisiebmaschine zur Verfügung, die eine zusätzliche definierte Fraktionierung gemischten Gutes ermöglicht. Dabei ist es unerheblich, ob bisher eine, zwei, oder drei definierte Fraktionen durch die jeweilige Trommelsiebmaschine zur Verfügung gestellt wurden. Es wird jeweils eine zusätzliche zu den bisher zur Verfügung gestellten Fraktionen, definierte Fraktion erreicht. Der anlagentechnische, aber auch verfahrenstechnische Aufwand wird reduziert, Energie gespart. Insbesondere durch die Anordnung des Scheibensiebes direkt auf dem Einlauftrichter der Trommelsiebmaschine ist dieser Vorteil besonders gegeben. Dadurch, dass das Scheibensieb auf dem Einlauftrichter der Trommelsiebmaschine angeordnet ist, wird in besonderem Maße der Vorteil der Erfindung wie zuvor beschrieben ersichtlich. Mit einer einfachen, jedoch wirksamen technischen Maßnahme erhält man eine Trommelsiebmaschine mit erheblich verbesserten Gebrauchseigenschaften.In a trommel screen automatically receives another, as defined to be considered, sieved fraction that exits at the end of the sieve drum out of this. The passage of the oversize grain is no longer permitted by the disc screen, as is still the case, for example, in the previously known stones. The invention then provides a tumbler which allows additional defined fractionation of blended material. It is irrelevant whether one, two, or three defined fractions have been provided by the respective drum screen. In each case, an additional fraction, which has been made available to date, has been reached. The technical and procedural costs are reduced and energy saved. In particular, by the arrangement of the disc screen directly on the inlet funnel of Trommelsiebmaschine this advantage is particularly given. Characterized in that the disc screen is arranged on the inlet funnel of Trommelsiebmaschine, the advantage of the invention will be particularly apparent as described above. With a simple but effective technical measure to obtain a drum screen with significantly improved performance characteristics.
Ein weiterer Aspekt der Erfindung betrifft eine Trommelsiebmaschine, wie zuvor beschrieben, die sich dadurch auszeichnet, dass das Scheibensieb wegklappbar bzw. wegschwenkbar ausgebildet ist. Dabei werden Wartungs- und Reinigungsarbeiten nicht unwesentlich erleichtert. Beispielsweise können Verstopfungen bei der Restmüllaufbereitung sehr leicht nach dem Wegschwenken des Scheibensiebes beseitigt werden.Another aspect of the invention relates to a trommel screen, as described above, which is characterized in that the disc screen is designed to fold away or wegschwenkbar. This maintenance and cleaning work is not insignificantly facilitated. For example, blockages in the processing of residual waste can be eliminated very easily after swinging away the screen screen.
Erfindungsgemäß wurde auch gefunden, dass es von Vorteil ist, wenn die Trommelsiebmaschine durch einen gemeinsamen Antrieb für die Siebtrommel und das Scheibensieb gekennzeichnet ist. Der maschinen- bzw. anlagen-technische Aufwand wird dadurch weiter verringert. Der Antrieb für eine Siebtrommel ist meist so dimensioniert, dass ein Scheibensieb durchaus mittels des Antriebes der Siebtrommel mit angetrieben werden kann. Für den Fall, dass der Antrieb einmal nicht so ausreichend dimensioniert ist, dass er beide Baugruppen antreiben kann, ist der Einsatz eines größer dimensionierten Antriebs meist günstiger als der Einsatz von zwei getrennten Antrieben.According to the invention it has also been found that it is advantageous if the drum screen is characterized by a common drive for the screen drum and the disc screen. The machine or plant technical effort is further reduced. The drive for a screen drum is usually dimensioned so that a disk screen can certainly be driven by means of the drive of the screen drum. In the event that the drive is not sufficiently dimensioned so that it can drive both modules, the use of a larger-sized drive is usually cheaper than the use of two separate drives.
Es ist weiterhin von Vorteil, wenn zumindest der Antrieb für die Siebtrommel der Trommelsiebmaschine als Direktantrieb, vorzugsweise als Direktantrieb mittels Ritzel, ausgebildet ist. Damit werden Aufwendungen für Getriebe eingespart. Die Drehzahlregelung ist bei modernen Antrieben über diesen selbst leicht steuerbar.It is furthermore advantageous if at least the drive for the sieve drum of the drum screening machine is designed as a direct drive, preferably as a direct drive by means of a pinion. This saves expenses for transmissions. The speed control is easily controllable on modern drives on this itself.
Eine Weiterbildung der erfindungsgemäßen zeichnet sich dadurch aus, dass das Scheibensieb in seinen Abmessungen der Größe des Einlauftrichters angepasst ist. Damit sind partielle Anpassungen bzw. Abdeckungen im Einfüllbereich nicht mehr notwendig.A development of the invention is characterized in that the disk screen is adapted in size to the size of the inlet funnel. This means that partial adjustments or covers in the filling area are no longer necessary.
Gemäß einer weiteren Ausführungsform der Erfindung ist es vorgesehen, dass das Scheibensieb in einem in Transportrichtung der Siebtrommel gesehen abfallenden Winkel (α) auf dem Einlauftrichter angeordnet ist. Hierdurch wird das Aus- bzw. Absieben des Überkoms und insbesondere sein Abtransport begünstigt. In gleicher Weise wird hierdurch erreicht, dass alle durch das Sieb definierten Körnungen des Siebgutes durch das Scheibensieb dann in die Siebtrommel gelangen.According to a further embodiment of the invention, it is provided that the disc screen is arranged in a direction of transport in the direction of the sieve drum sloping angle (α) on the inlet funnel. As a result, the extraction or removal of the excess and in particular its removal is favored. In the same way, this ensures that all grain sizes of the material to be screened through the screen are then passed through the disk screen into the screen drum.
Als weiterer Vorteil ist es gemäß einer Weiterbildung der erfindungsgemäßen Trommelsiebmaschine gefunden worden, wenn wenigstens eine Verstelleinrichtung vorgesehen ist, mittels derer der Winkel (α) des Scheibensiebes mit Bezug auf den Einlauftrichter veränderbar ist. Damit lässt sich der Winkel entsprechend des jeweils zu siebenden Gutes leicht variieren, wodurch eine weiter erhöhte Universalität der Trommelsiebmaschine erreicht wird.As a further advantage, it has been found according to a development of the trommel screen according to the invention, if at least one adjusting device is provided, by means of which the angle (α) of the disc screen with respect to the inlet funnel is variable. Thus, the angle can be slightly varied according to the respective goods to be screened, whereby a further increased universality of Trommelsiebmaschine is achieved.
Die erfindungsgemäße Trommelsiebmaschine zeichnet sich auch dadurch aus, dass eine Fördervorrichtung, beispielsweise ein Förderband oder eine Schurre, zum Abtransport des definierte Überkoms vorgesehen ist. Damit wird der Abtransport erheblich erleichtert. Beispielsweise kann das Überkom von dem Förderband oder der Schurre ggf. über ein weiteres Förderband dann erneut in eine Zerkleinerungsanlage geführt werden, bevor es dann erneut aber nochmals zerkleinert der Trommelsiebmaschine zugeführt wird.The drum screening machine according to the invention is also distinguished by the fact that a conveying device, for example a conveyor belt or a chute, is provided for the removal of the defined excess. Thus, the removal is greatly facilitated. For example, the Überkom of the conveyor belt or the chute, if necessary, then be passed through another conveyor belt again in a crushing plant, before it is then again but crushed again the Trommelsiebmaschine supplied.
Dabei ist es weiter von Vorteil, wenn die Fördereinrichtung mehrteilig, insbesondere abwinkel- bzw. wegschwenkbar ausgebildet ist. Insbesondere bei mobilen Anlagen ist dies eine Maßnahme, die den Transport der Maschine erleichtert.It is also advantageous if the conveyor is designed in several parts, in particular angled or wegschwenkbar. Especially in mobile systems, this is a measure that facilitates the transport of the machine.
Ein weiterer Vorteil der erfindungsgemäßen Trommelsiebmaschine ist gemäß einer Weiterbildung dadurch angegeben, dass die Förderrichtung der Fördereinrichtung für das abzutransportierende Überkom gegenläufig zu der Förderrichtung des gesiebten Gutes ist. Die Fraktionierung des gemischten Gutes wird dadurch in positiver Weise beeinflusst.A further advantage of the drum screening machine according to the invention is specified according to a development in that the conveying direction of the conveying device for the Überkom transported away is opposite to the conveying direction of the screened material. The fractionation of the mixed material is thereby positively influenced.
Erfindungsgemäß wurde auch gefunden, dass es von Vorteil ist, wenn die Fördereinrichtung mit Bezug auf die Förderrichtung des zu siebenden Gutes vor dem Einlauftrichter angeordnet ist. Die Vorteile, den Transport einer solchen Maschine betreffend, treten hier in gleicher Weise wie zuvor beschrieben ein.According to the invention it has also been found that it is advantageous if the conveyor is arranged with respect to the conveying direction of the goods to be screened in front of the inlet funnel. The advantages concerning the transport of such a machine occur here in the same way as described above.
Gemäß einer Weiterbildung der Trommelsiebmaschine, wie zuvor beschrieben, ist es vorgesehen, dass das Scheibensieb wechselbar bzw. abnehmbar ausgebildet ist, derart dass wenigstens ein Steingitter, Schwingsieb oder dergleichen anstelle des Scheibensiebes angeordnet werden kann. Dies bietet den Vorteil, dass die Maschine in bekannter Weise einsetzbar ist, wenn entsprechend der Ausbildung des Siebgutes der Einsatz eines Scheibensiebes nicht erforderlich ist.According to a further development of the trommel screen, as described above, it is provided that the screen screen is exchangeable or detachable, so that at least one stone mesh, vibrating screen or the like can be arranged instead of the screen screen. This offers the advantage that the machine can be used in a known manner, if according to the formation of the screenings the use of a screen screen is not required.
Dabei ist es entsprechend eines weiteren Aspektes der Lösung vorgesehen, dass das Steingitter bzw. das Schwingsieb ebenfalls klappbar bzw. wegschwenkbar ausgebildet ist. Auch hierdurch lassen sich Erleichterungen bezüglich der Wartung bzw. der Beseitigung von Störungen erreichen.It is provided according to a further aspect of the solution that the stone mesh or the vibrating screen is also formed foldable or wegschwenkbar. This also makes it easier to achieve maintenance or the elimination of disturbances.
Die Aufgabe der Erfindung wird auch gelöst durch ein Scheibensieb, insbesondere für eine Trommelsiebmaschine wie zuvor beschrieben, bestehend aus wenigstens zwei angetriebenen, mit Scheiben versehenen Wellen, wobei die Scheiben auf den verschiedenen Wellen versetzt bzw. kammartig ineinandergreifend zueinander angeordnet sind, das sich dadurch auszeichnet, dass die Wellen austauschbar ausgebildet sind. Die Austauschbarkeit der Wellen ermöglicht den Einsatz unterschiedlicher Wellen auf bzw. an einem Scheibensieb. Damit ist es auch gegeben, dass unterschiedliche Wellendurchmesser, unterschiedliche Scheibendurchmesser, unterschiedliche Scheibenabstände auf der Welle auf einem einzigen Grundkörper eines Scheibensiebes ermöglicht sind. Verschlissene Wellen lassen sich leicht wechseln. Auch das Umrüsten für unter-schiedliche Aufgaben ist jetzt sehr leicht möglich. Durch das Vorhalten unter-schiedlich bestückter Wellen ist ein universeller Einsatz gegeben.The object of the invention is also achieved by a disk screen, in particular for a drum screen as described above, consisting of at least two driven, provided with discs waves, the discs on the different waves offset or comb-like interdigitated to each other, which is characterized in that the shafts are exchangeable. The interchangeability of the shafts allows the use of different waves on or on a pulley screen. That's it Also given that different shaft diameters, different disc diameters, different disc spacings on the shaft on a single body of a disc screen are possible. Worn waves are easy to change. Also, the conversion for different tasks is now very easy. By providing differently equipped waves a universal use is given.
Eine vorteilhafte Weiterbildung des zuvor beschriebenen Scheibensiebes sieht daher vor, dass die Anzahl, die Größe und der Abstand der Scheiben zueinander auf den Wellen variierbar sind.An advantageous development of the disk screen described above therefore provides that the number, the size and the distance of the disks from one another to the waves are variable.
Ein weiterer Aspekt der Erfindung betrifft ein Scheibensieb, welches sich dadurch auszeichnet, dass wenigstens eine der Scheiben als von der Kreisform abweichendes Vieleck ausgebildet ist.Another aspect of the invention relates to a disk screen, which is characterized in that at least one of the discs is designed as a deviating from the circular polygon.
Es ist weiterhin vorgesehen, dass die Scheiben entsprechend einer Weiterbildung des zuvor beschriebenen Scheibensiebes austauschbar, insbesondere auf die Welle aufsteck- bzw. aufschiebbar ausgebildet sind. Damit können verschlissene Scheiben sehr bequem gewechselt werden. Auch lassen sich Scheiben unterschiedlicher Form und Größe auf einer Welle positionieren.It is further contemplated that the discs are interchangeable, in particular aufsteck- or pushed pushed on the shaft according to a development of the previously described Scheibensiebes. This allows worn discs to be changed very easily. Also discs of different shape and size can be positioned on a shaft.
Eine weitere erfindungsgemäße Variante des Scheibensiebes, wie zuvor beschrieben, zeichnet sich dadurch aus, dass Distanzstücke vorgesehen sind, die zwischen den Scheiben auf die Welle aufsteck- bzw. aufschiebbar sind und die mittels einer Spannvorrichtung auf der Welle gehalten sind. Damit ist der Austausch noch effizienter möglich.A further variant of the disc screen according to the invention, as described above, is characterized in that spacers are provided which can be pushed or pushed onto the shaft between the discs and which are held on the shaft by means of a tensioning device. This makes exchanges even more efficient.
Von Vorteil ist es weiterhin, wenigstens eine der Scheiben mit wenigstens einer Noppe zu versehen. Die Anordnung von Noppen führt zu einer weiteren Verbesserung des Siebergebnisses. Insbesondere wird verhindert, dass lange Stücke durch das Sieb treten können, die in ihren Abmessungen beispielsweise so dimensioniert sind, dass sie hochkant durch das Sieb gelangen könnten. Damit wird insgesamt die Einhaltung einer einmal vorgegebenen Korngröße noch besser gesichert.It is also advantageous to provide at least one of the discs with at least one nub. The arrangement of nubs leads to a further improvement of the sieving result. In particular, prevents long pieces can pass through the sieve, which are dimensioned, for example, in dimensions so that they could reach edgewise through the sieve. Overall, compliance with a given grain size is even better ensured.
Vorteilhafterweise ist die Noppe dabei am Umfang der Scheiben befestigt.Advantageously, the nub is attached to the circumference of the discs.
Dabei wurde gefunden, das es günstig ist, wenn die Scheiben mehrere am Umfang angeordnete Bohrungen besitzen, in welchen jeweils eine Noppe lösbar fest befestigbar bzw. anbringbar ist.It has been found that it is advantageous if the discs have a plurality of holes arranged on the circumference, in each of which a knob is releasably firmly fastened or attachable.
Entsprechend des Konzeptes der Erfindung, höchste Universalität der Trommelsiebmaschine zu gewährleisten, ist es weiterhin vorgesehen, dass die Noppen in ihrer Anzahl, Größe und Form variierbar, insbesondere wechselbar bzw. austauschbar ausgebildet sind.According to the concept of the invention, to ensure highest universality of the trommel screen, it is further provided that the knobs are variable in their number, size and shape, in particular changeable or interchangeable.
Die Noppen besitzen beispielsweise einen rechteckigen, quadratischen, runden bzw. ovalen Querschnitt. Die Form der Noppen, wie zuvor erwähnt, ist dabei keineswegs einschränkend zu verstehen. Sie richtet sich nach der jeweiligen Siebaufgabe.The knobs have, for example, a rectangular, square, round or oval cross-section. The shape of the pimples, as mentioned above, is by no means to be understood as limiting. It depends on the respective screening task.
Die Erfindung betrifft auch eine Trommelsiebmaschine mit einem Scheibensieb wie zuvor beschrieben.The invention also relates to a trommel screen having a screen screen as previously described.
Die Erfindung stellt auch eine Aufbereitung- bzw. Sortierungsanlage mit wenigstens einer Trommelsiebmaschine, wie zuvor beschrieben und/oder wenigstens einem Scheibensieb, wie zuvor beschrieben zur Verfügung.The invention also provides a treatment plant with at least one drum screening machine as described above and / or at least one disc screen as described above.

Am Ende der Siebtrommel 2 ist eine weitere Sammel- und Abtransportvorrichtung 6/2 angeordnet. Beim Siebvorgang ist diese heruntergelassen bzw. heruntergeklappt, so dass das innerhalb der Siebtrommel 2 nach hinten geführte Gut dort austreten kann und mittels der Vorrichtung, beispielsweise einem Transportband ebenfalls wegtransportiert werden kann. Das gesiebte Gut, welches in Transportrichtung A des zu siebenden Gutes am Ende der Siebtrommel 2 aus dieser ausgefördert wird, weist nach dem Stand der Technik im Durchschnitt noch größere Mengen an Überkorn auf, so dass dieses Gut noch einmal gesiebt werden oder insgesamt nochmals in eine Zerkleinerungsanlage gegeben werden muss, um es in einer bestimmten definierten Körnung zu erhalten.At the end of the screening drum 2, a further collecting and removal device 6/2 is arranged. During the sieving process, this is lowered or folded down so that the goods guided backwards within the screening drum 2 can exit there and can also be transported away by means of the device, for example a conveyor belt. The sieved Good, which is discharged in the transport direction A of the goods to be screened at the end of the screen drum 2, has according to the prior art, on average, even larger amounts of oversize, so that this Good be screened again or once again in a total Crushing plant must be given in order to obtain it in a certain defined grain size.
Dieses Problem wird nach der Erfindung durch die Anordnung eines zusätzlichen Scheibensiebes 5 auf bzw. vor der Trommelsiebmaschine 1 behoben. In der dargestellten Ausführungsform ist dabei das Scheibensieb 5 auf dem Einlauftrichter 4 angeordnet. Das Scheiben sieb 5 ist dabei in einem bezüglich zur Transportrichtung abfallendem Winkel α auf dem Einlauftrichter 4 angeordnet. Der Winkel α ist dabei entsprechend der jeweiligen Siebaufgabe unterschiedlich gestaltbar bzw. anpassbar. 'This problem is solved according to the invention by the arrangement of an
Das zu siebende Gut wird nach der Erfindung zunächst über das Scheibensieb 5 geführt, von dem die durch die Einstellung des Scheibensiebes 5 bestimmte Körnung in den Einlauftrichter 4 und dann in die Siebtrommel 2 gelangt. Die Siebtrommel 2 besitzt Öffnungen, die beispielsweise nach dem Unterkorn für das Siebgut definiert sein können. Dieses Unterkorn wird dann von der Sammel- und Abtransportvorrichtung 6/1 aufgefangen und abtransportiert. Das jetzt durch die Einstellung des Scheibensiebes 5 und die Größe der Öffnungen der Siebtrommel 2 bestimmte Gut gelangt zum Ende der Siebtrommel 2 und tritt dort dann aus dieser auf die Sammel- und Abtransportvorrichtung 6/2 aus.The material to be screened is first passed, according to the invention, over the
Das Überkorn, welches nicht durch die Siebtrommel gelangt, wird von dem Scheibensieb 5 auf eine Fördereinrichtung 6/3 gefördert, die in einer Förderrichtung B fördert, die gegenläufig zur Förderrichtung A des zu siebenden Gutes in der Siebtrommel 2 ist. Die Fördereinrichtung 6/3 ist in der Darstellung gemäß der
Somit erhält man mit einer Trommelsiebmaschine 1 nach dem zuvor beschriebenen Ausführungsbeispiel zwei definierte Fraktionen des Mischgutes zur sofortigen Verwendung bzw. Weiterverarbeitung und das Überkorn, welches ggf. nochmals einer Zerkleinerungsvorrichtung zuzuführen ist.
