Description

Die vorliegende Erfindung betrifft eine Zerkleinerungsvorrichtung, bekannt z.B. aus DE-A-196 12 159, zur Zerkleinerung von Schüttgutpartikeln, insbesondere Korn- oder Fascrpartikel, mit zumindest zwei gegensinnig angetriebenen Zerkleinerungswalzen, zwischen denen zumindest eine Eingriffspaarung aus einem Radialsteg der einen Walze und einer Radialnut der anderen Walze gebildet ist, deren Flanken parallel und unter einem Winkel 0 < α < 90° zu Walzenlängsachsen angeordnet sind, derart, dass zwischen zwei benachbarten Flanken ein Parallelspalt ausgebildet ist.The present invention relates to a crushing device known e.g. from DE-A-196 12 159, for the comminution of bulk material particles, in particular grain or Fascrpartikel, with at least two counter-rotating crushing rollers, between which at least one engagement pair of a radial web of a roller and a radial groove of the other roller is formed, whose flanks parallel and are arranged at an angle 0 <α <90 ° to roll longitudinal axes, such that between two adjacent flanks, a parallel gap is formed.

Zerkleinerungsvorrichtungen der eingangs genannten Art werden beispielsweise als so genannte Nachzerkleincrungseinrichtungen zur weiteren Zerkleinerung von Häckselgut eingesetzt. Dabei kann es sich beispielsweise um Erntegut oder auch um fein zerteiltes faseriges organisches Gut handeln, das zur Komposticrung in Biokompostanlagen oder zur Beschickung von Biogasanlagen dient.Crushing devices of the type mentioned are used for example as so-called Nachzerkleincrungseinrichtungen for further crushing shredded material. This may, for example, be harvested material or finely divided fibrous organic material used for composting in biocomposting plants or for charging biogas plants.

Ein weiterer Einsatzbereich für Zerkleinerungsvorrichtungen der eingangs genannten Art ist deren Verwendung als Mahleinrichtung, um Körnerfrüchte zu zerkleinern bzw. entsprechende kornförmige Partikel aufzuschließen, um die Qualität von körnigem Tierfutter zu erhöhen. So ist es beispielsweise bekannt, Hafer vor der Verfütterung in einer so genannten Haferquetsche, in der das Haferkorn durch Zerquetschen aufgeschlossen wird, zu behandeln.Another application for crushing devices of the type mentioned is their use as a grinder to order To break up grains or to digest corresponding grain-shaped particles in order to increase the quality of granular animal feed. Thus, it is known, for example, to treat oats before being fed in a so-called oat press, in which the oat grain is disrupted by crushing.

Bei den vorgenannten Einsatzarten ergeben sich im Betrieb der bekannten Zerkleinerungsvorrichtungen, je nachdem, ob es sich bei dem zu zerkleinernden Gut um Korn- oder Faserpartikel handelt, besondere Probleme. Bei kornförmigen Partikeln ergibt sich häufig eine ungleichförmige Quetschwirkung, so dass manche Körner nur leicht angequetscht werden, andere durch den Druck im Walzenspalt völlig zerstört werden. Je nach Feuchtegehalt des verwendeten Korns kann es auch zu Verklebungen im Walzenspalt kommen, die den Durchsatz behindern. Die Gefahr der Zusetzung des Walzenspalts infolge einer ungleichmäßigen Zerkleinerung und eines relativ hohen Restfeuchtegehalts besteht insbesondere auch beim Zerkleinern von nicht ausreichend dehydriertem Fasergut.In the aforementioned types of use arise in the operation of the known crushing devices, depending on whether it is to be shredded Good to grain or fiber particles, special problems. In granular particles often results in a non-uniform squeezing, so that some grains are only slightly squeezed, others are completely destroyed by the pressure in the nip. Depending on the moisture content of the grain used, it can also lead to gluing in the nip, which hinder the throughput. The risk of clogging of the nip as a result of uneven comminution and a relatively high residual moisture content in particular also exists in the comminution of insufficiently dehydrated fiber material.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Zerkleinerungsvorrichtung vorzuschlagen, die Abhilfe bei den vorgenannten Problemen schafft und insbesondre als Folge eines gleichmäßigen Zerkleinerungseffekts einen hohen Durchsatz ermöglicht.The present invention has for its object to provide a crushing device, which provides relief in the aforementioned problems and in particular allows high throughput as a result of a uniform crushing effect.

Diese Aufgabe wird durch eine Zerkleinerungsvorrichtung mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a crushing device having the features of claim 1.

Bei der erfindungsgemäßen Zerkleinerungsvorrichtung sind die den parallelen Walzenspalt begrenzenden Flanken mit einem Gewindeprofil versehen.In the comminution device according to the invention, the flanks delimiting the parallel nip are provided with a thread profile.

Bereits durch die Profilierung der Flanken als solche wird eine Verlängerung der effektiven Spaltlänge zwischen den Flanken erreicht, was sich bereits vorteilhaft auf den möglichen Durchsatz auswirkt. Darüber hinaus sorgt die Ausbildung der Profilierung als Gewindeprofil bei gegensinniger Rotation der Flanken für einen erhöhten Schereffekt zwischen den Flanken, da die Gewindegänge Abscherkanten definieren.Already by the profiling of the flanks as such, an extension of the effective gap length between the flanks is achieved, which already has an advantageous effect on the possible throughput. Furthermore the formation of the profiling as a thread profile with opposite rotation of the flanks ensures an increased shear effect between the flanks, since the threads define shearing edges.

Ein besonders hoher Schereffekt lässt sich erzielen, wenn die Gewindeprofile der den Parallelspalt begrenzten Flanken gegenläufig ausgebildet sind, so dass das Gewindeprofil der einen Flanke ein Rechtsgewinde definiert und das Gewindeprofil der gegenüberliegenden Flanke ein Linksgewinde.A particularly high shear effect can be achieved if the thread profiles of the flanks delimited by the parallel gap are formed in opposite directions, so that the thread profile of one flank defines a right-hand thread and the thread profile of the opposite flank a left-hand thread.

Wenn der Radialsteg ein Doppelkeilprofil aufweist, das in eine komplementär ausgebildete, im Profil V-förmige Radialnut eingreift, lässt sich eine Verdopplung der Länge des Parallelspalts auf kleiner Länge der Zerkleinerungswalzen erzielen.If the radial web has a double wedge profile, which engages in a complementarily formed, in profile V-shaped radial groove, a doubling of the length of the parallel nip on a small length of the crushing rollers can be achieved.

Wenn eine Vielzahl von Eingriffspaarungen ausgebildet ist, derart, dass beide Walzen in alternierender Reihenfolge und in gleichmäßiger Teilung eine Vielzahl von Radialstegen und Radialnuten aufweisen, die sich wechselweise im Eingriff miteinander befinden, so dass die Radialstege der einen Walze in die Radialnuten der anderen Walze eingreifen und umgekehrt, lässt sich die gesamte zur Verfügung stehende Länge der Zerkleinerungswalze in besonders effektiver Weise nutzen.When a plurality of mating pairings are formed, such that both of the rolls have a plurality of radial lands and radial grooves in alternating order and pitch, which are mutually engaged, so that the radial lands of one roll engage the radial grooves of the other roll and vice versa, the entire available length of the crushing roller can be used in a particularly effective manner.

Um sicherzustellen, dass die gesamte für die Zerkleinerung vorgesehene Schüttgutmenge durch den Walzenspalt gefördert wird, können die Walzen jeweils mit einer komplementär zum Längsprofil der Walzen ausgebildeten, einen Einzugsspalt begrenzenden Abstreifvorrichtung versehen sein.In order to ensure that the entire quantity of bulk material intended for comminution is conveyed through the nip, the rolls can each be provided with a stripping device designed to be complementary to the longitudinal profile of the rolls and defining a draw-in gap.

Um eine definierte Zerkleinerung des zur Zerkleinerung vorgesehenen Schüttguts zu ermöglichen, kann zumindest eine der Zerkleinerungswalzen mit einer senkrecht zur Längsachse der anderen Zerkleinerungswalze wirkenden Zustelleinrichtung versehen sein.In order to enable a defined comminution of the bulk material intended for comminution, at least one of the comminuting rollers can be provided with an advancing device acting perpendicular to the longitudinal axis of the other comminution roller.

Bei einer weiteren Ausführungsform der Zerkleinerungsvorrichtung ist das Gewindeprofil mit zumindest einer quer zu einem Gewindegang verlaufenden Mitnehmerkante versehen, so dass insbesondere der Einzug von relativ grobkörnigen Partikeln bzw. Schüttgutpartikeln, die insbesondere aufgrund ihres dehydrierten Zustands eine besondere Härte aufweisen, in den Parallelspalt bzw. die Zerkleinerung im Parallelspalt verbessert wird. Der Mitnehmerkante kommt daher eine Doppelfunktion zu, nämlich zum einen eine verbesserte Mitnahme der zugeführten Partikel in den Parallelspalt als auch zum anderen eine Schneidenwirkung zur Erzielung eines verbesserten Zerkleinerungseffekts. Bei den vorstehend erwähnten Partikeln kann es sich beispielsweise um Maiskörner, Sojabohnen oder auch Erbsen handeln. Eine verbesserte Zerkleinerungswirkung ist jedoch grundsätzlich auch bei kleinkörnigem Getreide, wie beispielsweise Weizen, Hafer oder Gerste feststellbar.In a further embodiment of the comminution device, the thread profile is provided with at least one entrainment edge running transversely to a thread, so that in particular the entry of relatively coarse-grained particles or bulk material particles, which have a particular hardness due to their dehydrated state, into the parallel gap or the Shredding in the parallel gap is improved. The driving edge therefore has a double function, namely, on the one hand, improved entrainment of the supplied particles into the parallel gap and, on the other hand, a cutting action for achieving an improved comminution effect. The particles mentioned above may be corn kernels, soybeans or peas, for example. However, an improved comminuting effect is generally detectable even with small grain crops such as wheat, oats or barley.

Ein besonders guter Mitnahmeeffekt als auch ein besonders guter Schneideffekt lässt sich erzielen, wenn die Mitnehmerkante durch eine unter einem Winkel β zur Eingriffsflanke geneigt angeordnete Schnittfläche gebildet ist.A particularly good entrainment effect as well as a particularly good cutting effect can be achieved if the driving edge is formed by an inclined surface arranged at an angle β to the engaging edge.

Wenn darüber hinaus eine Vielzahl von Mitnehmerkanten eine lineare Mitnehmeranordnung bildet, die sich über die Eingriffsflanke erstreckt, wird im gesamten Parallelspalt die Erzielung der vorgeschilderten Effekte ermöglicht.In addition, if a plurality of entrainment edges forms a linear cam arrangement which extends over the engaging edge, the achievement of the pre-recorded effects is made possible in the entire parallel gap.

Als vorteilhaft für die Wirkung der Mitnehmerkanten hat sich auch herausgestellt, die Mitnehmeranordnung radial auszurichten.As advantageous for the effect of Mitnehmerkanten has also been found to align the driver assembly radially.

Wenn auf der Eingriffsflanke verteilt eine Vielzahl von Mitnehmeranordnungen ausgebildet ist, die in besonders vorteilhafter Weise darüber hinaus noch äquidistant angeordnet sind, ist sowohl hinsichtlich der Einzugsbedingungen in den Parallelspalt als auch hinsichtlich der Zerkleinerungsleistung eine besonders vorteilhafte Ausführung realisiert.If distributed on the engaging edge a plurality of Mitnehmeranordnungen is formed, which are arranged in a particularly advantageous manner beyond even equidistant, a particularly advantageous embodiment is realized both in terms of the Einzugsbedingungen in the parallel gap and in terms of crushing performance.

Nachfolgend wird anhand der Zeichnungen eine bevorzugte Ausführungsform der Zerkleinerungsvorrichtung näher erläutert.Hereinafter, a preferred embodiment of the crushing device will be explained in more detail with reference to the drawings.

Fig. 1 zeigt eine Zerkleinerungsvorrichtung 10 mit zwei in einem gemeinsamen Maschinengehäuse 11 angeordneten Zerkleinerungswalzen 12, 13, die entsprechend den Drehrichtungspfeilen gegenläufig angetrieben sind, derart, dass im dargestellten Ausführungsbeispiel die in Fig. 1 links dargestellte Zerkleinerungswalze 12 im Uhrzeigersinn und die inFig. 1 rechts dargestellte Zerkleinerungswalze 13 entgegen dem Uhrzeigersinn angetrieben wird. Wie Fig. 1 ferner zeigt, ist oberhalb eines Eingriffsbereichs 14 der Zerkleinerungswalzen 12, 13 am Maschinengehäuse 11 ein Zuführtrichter 15 und unterhalb des Eingriffsbereichs 14 ein Auswurfstutzen 16 ausgebildet. Zur Abdichtung eines Einzugsbereichs 17 oberhalb des Eingriffsbereichs 14 und eines Auswurfsbereichs 18 unterhalb des Eingriffsbereichs 14 gegenüber dem Maschinengehäuse 11 sind bei beiden Zerkleinerungswalzen 12, 13 parallel zu Walzenlängsachsen 19, 20 Abstreifvorrichtungen 21 vorgesehen, die, wie in Fig. 2 dargestellt, mit Abstreifzungen 22 in das Längsprofil der Zerkleinerungswalzen 12, 13 eingreifen. Die Abstreifvorrichtungen 21 verhindern dabei insbesondere, dass in den Zuführtrichter 15 eingebrachtes, hier beispielsweise kornförmig ausgebildetes Schüttgut 23 im Einzugsbereich 17 oder dem Auswurfbereich 18 in das Maschinengehäuse 11 eindringt. Fig. 1 shows a crushing device 10 with two arranged in a common machine housing 11 crushing rollers 12, 13, which are driven in opposite directions according to the direction of rotation arrows, such that in the illustrated embodiment, the left in Fig. 1 illustrated crushing roller 12 in the clockwise direction and in Fig. 1 right crushing roller 13 is driven counterclockwise. 1 further shows, above an engagement region 14 of the comminution rollers 12, 13 on the machine housing 11, a supply funnel 15 and below the engagement region 14, an ejection nozzle 16 is formed. For sealing a catchment area 17 above the engagement area 14 and an ejection area 18 below the engagement area 14 with respect to the machine housing 11 stripping devices 21 are provided at both comminution rollers 12, 13 parallel to roller longitudinal axes 19, 20, which, as shown in Fig. 2 , with Abstreifzungen 22nd in the longitudinal profile of the crushing rollers 12, 13 engage. The stripping devices 21 prevent in particular that introduced into the feed hopper 15, here, for example, grain-shaped bulk material 23 in the catchment area 17 or the ejection area 18 penetrates into the machine housing 11.

Fig. 3 zeigt die im Schnitt dargestellten, in ihrem Eingriffsbereich 14 ineinander greifend angeordneten Zerkleinerungswalzen 12, 13 in Zuführrichtung des Schüttguts 23 gesehen. FIG. 3 shows the comminution rollers 12, 13, which are shown in section and engage in one another in their engagement region 14, viewed in the feed direction of the bulk material 23.

Wie Fig. 3 zeigt, sind die Zerkleinerungswalzen 12, 13 in ihrem Längsprofil definiert durch eine alternierende Anordnung von Radialstegen 24 und Radialnuten 25, die durch schräg zu den Walzenlängsachsen 19, 20 angeordnete Eingriffsflanken 26, 27 begrenzt sind. Die Eingriffsflanken 26, 27 sind jeweils paarweise schräg zueinander angestellt, so dass die Radialstege 24 im dargestellten Ausführungsbeispiel ein Doppelkeilprofil in der in Fig. 3 gewählten Längsschnittdarstellung der Zerkleinerungswalzen 19, 20 aufweisen mit einem Keilwinkel α gemessen zur Walzenlängsachse 19, 20, der im vorliegenden Fall etwa 60 ° beträgt. Wie Fig. 3 deutlich zeigt, entsteht durch die alternierende, von Radialnuten 25 unterbrochene Anordnung der Radialstege 24 ein sägezahnartiges Längsprofil der Zerkleinerungswalzen 12, 13.As FIG. 3 shows, the comminution rollers 12, 13 are defined in their longitudinal profile by an alternating arrangement of radial webs 24 and radial grooves 25, which are delimited by engagement flanks 26, 27 arranged obliquely to the roller longitudinal axes 19, 20. The engaging flanks 26, 27 are each set in pairs at an angle to each other, so that the radial webs 24 in the illustrated embodiment, a double wedge profile in the selected in Fig. 3 longitudinal sectional view of the crushing rollers 19, 20 with a wedge angle α measured to the roll axis 19, 20, in the present Case is about 60 °. As FIG. 3 clearly shows, a sawtooth-like longitudinal profile of the comminution rollers 12, 13 is produced by the alternating arrangement of the radial webs 24 interrupted by radial grooves 25.

Wie in Fig. 3 dargestellt, ist es möglich, das vorstehend erwähnte sägezahnartige Längsprofil der Zerkleinerungswalzen 12, 13 auf unterschiedliche Weise zu erzeugen. So kann, wie am Beispiel der Zerkleinerungswalze 12 dargestellt, die Zerkleinerungswalze 12 einstückig ausgebildet sein oder, wie am Beispiel der Zerkleinerungswalze 13 dargestellt, die Zerkleinerungswalze 13 durch wechselsinnige Anordnung von Scheiben 27 auf einer Welle 28 erzeugt werden.As shown in Fig. 3 , it is possible to have the above-mentioned sawtooth-like longitudinal profile of the crushing rollers 12, 13 to different Way to produce. Thus, as shown by the example of the crushing roller 12, the crushing roller 12 may be integrally formed or, as shown by the example of the crushing roller 13, the crushing roller 13 are generated by a change-wise arrangement of discs 27 on a shaft 28.

Wie aus der Schnittdarstellung der in Fig. 4 dargestellten Zerkleinerungswalze 13 zu ersehen ist, ist die Eingriffsflanke 27 des Radialstegs 24 mit einem im vorliegenden Fall rechtsgängigen Gewinde 29 versehen, derart, dass sich ein Gewindegang 30 auf der Eingriffsflanke 27 von einem Wellenquerschnitt 31 der Zerkleinerungswalze 13 zu einem Außenumfang 32 des Radialstegs 24 hin erstreckt. Aufgrund des wechselseitigen Eingriffs der Radialstege 24 der einen Zerkleinerungswalze 12 und der Radialnuten 25 der zugeordneten Zerkleinerungswalze 13 im Eingriffsbereich 17 ergibt sich der in Fig. 3 dargestellte zickzackartige Verlauf eines Parallelspalts 33 zwischen den Zerkleinerungswalzen 12, 13. Zur Erläuterung der Verhältnisse in einem Parallelspaltabschnitt 34 ist in Fig. 5 ein vergrößerter Ausschnitt des Parallelspaltabschnitts 34 mit dazwischenliegender Anordnung eines, hier als Getreidekorn ausgebildeten Schüttgutpartikels 35 dargestellt.As can be seen from the sectional view of the crushing roller 13 shown in Fig. 4 , the engaging edge 27 of the radial web 24 is provided with a right-hand thread 29 in the present case, such that a thread 30 on the engaging edge 27 of a shaft cross-section 31 of the crushing roller 13 to an outer periphery 32 of the radial web 24 extends. Due to the mutual engagement of the radial webs 24 of a crushing roller 12 and the radial grooves 25 of the associated crushing roller 13 in the engaging portion 17 results in the shown in Fig. 3 zigzag course of a parallel nip 33 between the crushing rollers 12, 13. To explain the conditions in a parallel nip section 34th FIG. 5 shows an enlarged detail of the parallel gap section 34 with an arrangement therebetween of a bulk particle 35 embodied here as a grain of grain.

Wie durch die Richtungspfeile 36, 37 im Parallelspaltabschnitt 34 in Fig. 3 angedeutet, weisen die den Parallelspaliabschnitt 34 begrenzenden Eingriffsflanken 26, 27 gegenläufig orientierte Gewinde 29 auf, derart, dass bezogen auf die Drehrichtung der Zcrkleinerungswalze 13 im Uhrzeigersinn das Gewinde auf der Eingriffsflanke 27 der Zerkleinerungswalze 13 rechtsgängig und das Gewinde der im Parallelspaltabschnitt 34 gegenüberliegenden Eingriffsflanke 26 bei Drehung der Zerkleinerungswalze 12 entgegen dem Uhrzeigersinn linksgängig ausgebildet ist. Hierdurch entstehen, wie auch in Fig. 5 dargestellt, durch die gegenläufige Drehrichtung der Gewindegänge 30 in dem Schüttgutpartikel 35 hohe Scherkräfte, die für einen Aufschluss des Schüttgutpartikels 35 sorgen.As indicated by the directional arrows 36, 37 in the parallel-slit section 34 in FIG. 3 , the engagement flanks 26, 27 delimiting the parallel-splitting section 34 have oppositely oriented threads 29, such that the thread on the engagement flank 27 is clockwise relative to the direction of rotation of the reduction roller 13 the crushing roller 13 is right-handed and the thread of the opposite in the parallel nip portion 34 engaging edge 26 is formed counterclockwise on rotation of the crushing roller 12 counterclockwise. As a result, as also shown in FIG. 5 , due to the opposite direction of rotation of the threads 30 in the bulk material particle 35, high shear forces, which provide for disruption of the bulk material particle 35, are produced.

Zur Einstellung der in Fig. 5 dargestellten Spaltbreite Z ist die in Fig. 3 dargestellte Zerkleinerungswalze 13 mit einer Zustelleinrichtung 38 versehen, die eine bezogen auf die Walzenlängsachsen 19, 20 parallele Zustellbewegung der Zerkleinerungswalze 13 auf die Zerkleinerungswalze 12 zu oder von dieser weg ermöglicht. Hierdurch ist es möglich, die für die jeweilige Größe der Schüttgutpartikel 35 optimale Spaltbreite Z einzustellen.To set the gap width Z shown in Fig. 5 , the crushing roller 13 shown in Fig. 3 is provided with a feed device 38 which allows a relative to the roller longitudinal axes 19, 20 parallel feed movement of the crushing roller 13 to the crushing roller 12 to or away. This makes it possible to set the optimum gap width Z for the respective size of the bulk material particles 35.

Wie aus der Schnittdarstellung einer in Fig. 6 dargestellten Zerkleinerungswalze 39 zu ersehen ist, die vorzugsweise mit einer gleichartig ausgebildeten weiteren Zerkleinerungswalze kombiniert entsprechend der in Fig. 1 dargestellten Zerkleinerungswalzenpaarung der Zerkleinerungswalzen 12, 13 verwendbar ist, weist die Zerkleinerungswalze 39 eine Eingriffsflanke 40 auf, die in Übereinstimmung mit der in Fig. 4 dargestellten Zerkleinerungswalze 13 ein rechtsgängiges Gewinde 41 aufweist, derart, dass sich ein Gewindegang 42 auf der Eingriffsflanke 40 von einem Wellenquerschnitt 31 der Zerkleinerungswalze 39 zu einem Außenumfang 32 des Radialstcgs 24 hin erstreckt.As can be seen from the sectional view of a comminution roller 39 shown in FIG. 6 , which is preferably usable in combination with a similar further comminuting roller in accordance with the comminution roller pairing of the comminuting rollers 12, 13 shown in FIG. 1 , the comminuting roller 39 has an engaging flank 40, which in accordance with the crushing roller 13 shown in Fig. 4 has a right-hand thread 41, such that a thread 42 extends on the engaging edge 40 of a shaft cross-section 31 of the crushing roller 39 to an outer periphery 32 of Radialstcgs 24 out.

Im Unterschied zu dem in Fig. 4 dargestellten Gewindegang 30 ist der Gewindegang 42 der Zerkleinerungswalze 39 mit einer Mitnehmereinrichtung 43 versehen, die eine Mehrzahl von radial verlaufenden Mitnehmeranordnungen 44 aufweist. Die Mitnehmeranordnung 44 weist radialfluchtend miteinander angeordnete Mitnehmerkanten 45 auf, die in sämtlichen Windungen des Gewindegangs 42 ausgebildet sind. Von der Vielzahl von Mitnehmeranordnungen 44 ist in Fig. 6 lediglich eine Mitnehmeranordnung 44 beispielhaft dargestellt, wobei gleichzeitig zur Erläuterung der Ausbildung der Mitnehmeranordnung 44 ein als Sägeblatt 46 ausgebildetes Schneidwerkzeug mit angedeutetem Umriss dargestellt ist. Sowohl in Fig. 6 als auch in der Darstellung der Seitenansicht der Eingriffsflanke 40 in Fig. 7 sind die durch den Einsatz des hier als Sägeblatt 46 ausgebildeten Schneidwerkzeugs bei der Herstellung der Mitnehmeranordnungen 44 entstehenden Schnittflächen 47 dargestellt.In contrast to the thread 30 shown in FIG. 4 , the thread 42 of the comminuting cylinder 39 is provided with a carrier device 43, which has a plurality of radially extending driver arrangements 44. The driver assembly 44 has radially aligned Mitnehmerkanten 45 which are formed in all turns of the thread 42. Of the large number of driver arrangements 44, only one driver arrangement 44 is shown by way of example in FIG. 6 , wherein a cutting tool designed as a saw blade 46 is also shown with an indicated outline in order to explain the design of the driver arrangement 44. Both in FIG. 6 and in the illustration of the side view of the engagement flank 40 in FIG. 7 , the cut surfaces 47 resulting from the use of the cutting tool designed here as a saw blade 46 are shown in the production of the driver arrangements 44.

Wie aus einer Zusammenschau der Fig. 6 und 7 deutlich wird, wird zur Herstellung der Mitnehmeranordnungen 44 das rotierende Sägeblatt 46 längs einer entsprechend dem Keilwinkel α geneigten Radialen 48 geführt, wobei das Sägeblatt 46 um den Winkel β zur Ebene der Eingriffsflanke 40 geneigt ist. Hierdurch entstehen die in den Fig. 6 und 7 schraffiert dargestellten Schnittflächen 47, die unter dem Winkel β geneigt zur Ebene der Eingriffsflanke 40 orientiert sind. Die hierdurch längs der Radialen 48 gebildeten Mitnehmerkanten 45 bilden in linearer Anordnung jeweils eine Mitnehmeranordnung 44.As is clear from a combination of Figs. 6 and 7 , the rotating saw blade 46 is guided along a corresponding to the wedge angle α inclined radials 48, wherein the saw blade 46 is inclined by the angle β to the plane of the engaging edge 40 for producing the Mitnehmeranordnungen 44. This results in the cross-sectional areas 47 shown hatched in FIGS. 6 and 7 , which are oriented at an angle β inclined to the plane of the engaging flank 40. The driver edges 45 formed thereby along the radial 48 form in each case a driver arrangement 44 in a linear arrangement.

Bei Rotation der in Fig. 6 dargestellten Zerkleinerungswalze 39 entsprechend dem Drehrichtungspfeil 49, also entgegen dem Uhrzeigersinn werden jeweils gemäß der Darstellung in Fig. 6 rechts der Mitnehmeranordnungen 44 bzw. der Mitnehmerkanten 45 im Parallelspalt 33 (Fig. 1) angeordnete Partikel erfasst und durch die in Fig. 1 angedeuteten, im Eingriffsbereich 14 gegeneinander rotierenden Mitnehmeranordnungen 44 abgeschert.Upon rotation of the crushing roller 39 shown in Fig. 6 corresponding to the direction of rotation arrow 49, ie counterclockwise as shown in Fig. 6 right of Mitnehmeranordnungen 44 and the Mitnehmerkanten 45 in the parallel gap 33 ( Fig The indicated in Fig. 1 , in the engagement region 14 against each other rotating Mitnehmeranordnungen 44 sheared.
