Abstract

The invention relates to a roller mill having a modular design. In order to make possible an increased nominal grinding capacity with a limited roll/oscillating lever mass and with a greater number of rolls, the supports are transferred toward the outside, and the oscillating lever pins, with regard to the transferred stands, are arranged in an off-center and radially inward manner between the grinding plate and the support.

Description

Wälzmühle in ModulbauweiseRoller mill in modular design
Die Erfindung betrifft eine Wälzmühle gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a roller mill according to the preamble of claim 1.
Wälzmühlen in Modulbauweise können beispielsweise nach dem LOESCHE-System aufgebaut sein. Bei diesen Wälzmühlen wird als Baustein eine Krafteinheit eingesetzt, die aus einem Ständer mit einer Schwinghebellagerung für einen Schwinghebel und darin geführter Mahlwalze, einer Schwinghebelabdichtung gegenüber dem Mühlengehäuse und einem hydropneuma- tischen Federungssystem besteht ( DE 196 03 655 Al ) .Roller mills in modular design can be constructed, for example, according to the LOESCHE system. In these Wälzmühlen a power unit is used as a building block, which consists of a stand with a rocker arm bearing for a rocker arm and guided therein grinding roller, a rocker arm seal against the mill housing and a hydropneumatic suspension system (DE 196 03 655 Al).
Ein Vorteil der Modulbauweise ist eine mit einem relativ geringen Aufwand realisierbare Mühlenkonstruktion entsprechend der jeweils geforderten Mahlleistung .An advantage of the modular construction is a mill construction which can be realized with a relatively low outlay in accordance with the required grinding capacity.
Grundsätzlich sind Wälzmühlen mit zwei , drei, vier oder mehr, auf einer rotierenden Mahlschüs'sel abrollenden Mahlwalzen bekannt . Luftstrom-Wälzmühlen in Modulbauweise nach dem Loesche-System wurden bisher in Anordnungen mit zwei, drei und vier Walzen realisiert . Die bisher größte Loe- sche-Wälzmühle für die Zementindustrie verfügt über eine Nenn-Mahlleistung von 840 t/h für Zement-Rohmaterial . Bei dieser Mühle beträgt das Gewicht einer Mahlwalze mit Schwinghebel etwa 90 t . In principle, roller mills with two, three, four or more, rolling on a rotating Mahlschüs'sel grinding rollers are known. Modular air flow roller mills according to the Loesche system have hitherto been implemented in arrangements with two, three and four rollers. The largest Loech roller mill for the cement industry to date has a nominal grinding capacity of 840 t / h for cement raw material. In this mill, the weight of a grinding roller with rocker arm is about 90 t.
Inzwischen besteht der Bedarf, insbesondere in der Zementindustrie, nach noch höheren Nenn-Produktraten. Zur Realisierung besteht grundsätzlich die Möglichkeit, größere Mahlwalzen, zum Beispiel in einer 4-Walzenmühle, anzuordnen.There is now a demand for even higher nominal product rates, especially in the cement industry. To realize basically there is the possibility to arrange larger grinding rolls, for example in a 4-roll mill.
Größere Mahlwalzen weisen jedoch eine wesentlich höhere Walzen-/Schwinghebelmasse auf, welche zu einer Zunahme der Maschinenschwingungen während der Mahlbetriebs sowie zu höheren Kosten der Mahlwalzen und der damit verbundenen Kraftübertragungssysteme führt . Weitere Nachteile sind der relativ große Platzbedarf beim Montieren und Demontieren der Mahlwalzen und die hierfür notwendigen schweren Hebezeuge.However, larger grinding rolls have a significantly higher roll / rocker mass, which results in an increase in machine vibration during the grinding operation as well as higher costs of the grinding rolls and the associated power transmission systems. Other disadvantages are the relatively large footprint in mounting and dismounting of the grinding rollers and the necessary heavy lifting equipment.
Eine Erhöhung der Kapazität einer Wälzmühle kann grundsätzlich auch mit einer größeren Walzenzahl , beispielsweise mit fünf oder sechs Mahlwalzen erreicht werden. Dies bedeutet eine entsprechende Anhebung der Ständeranzahl und einen geringeren Abstand zwischen den Ständern.An increase in the capacity of a roller mill can in principle also be achieved with a larger number of rolls, for example with five or six grinding rolls. This means a corresponding increase in the number of stands and a smaller distance between the stands.
Eine höhere Nenn-/Mahlleistung erfordert jedoch auch die Zuführung höherer Gasströme und somit einen größeren Ringkanal bzw. Gaskanäle mit einem größeren Durchmesser. Für eine höhere Ständerzahl und ausreichend dimensionierte Gaskanäle ist am Mühlenumfang nicht genügend Platz . Auch der Ausbauraum für eine Montage und Demontage des Mühlengetriebes und der Mahlschüssellagerung wäre nicht realisierbar.However, a higher nominal / grinding power also requires the supply of higher gas flows and thus a larger annular channel or gas channels with a larger diameter. For a higher number of stands and adequately sized gas ducts there is not enough room at the circumference of the mill. Also, the installation space for assembly and disassembly of the mill gear and the grinding bowl storage would not be feasible.
Der Erfindung liegt die A u f g a b e zugrunde, eine Wälzmühle in Modulbauweise zu schaffen, bei welcher unter Beibehaltung der Vorteile der Modulbauweise einer 4-Walzen- mühle mit einer größeren Anzahl Mahlwalzen eine erhebliche Steigerung der Mahl-Nennleistung bei gleichzeitig ausreichendem Platzangebot für Montage- und Wartungsarbeiten gewährleistet ist . Erfindungsgemäß wird die Aufgabe durch die Merkmale des Anspruchs 1 gelöst . Zweckmäßige und vorteilhafte Ausgestaltungen sind in den Unteransprüchen und in der Figurenbeschreibung enthalten.The invention has for its object to provide a roller mill in modular design, in which while maintaining the advantages of the modular design of a 4-roll mill with a larger number of grinding rollers a significant increase in grinding nominal power while sufficient space for installation and maintenance is guaranteed . According to the invention the object is achieved by the features of claim 1. Advantageous and advantageous embodiments are contained in the subclaims and in the description of the figures.
Ein Grundgedanke der Erfindung kann darin gesehen werden, die Position der Schwinghebelachsen in Bezug auf den jeweils zugehörigen Ständer derart zu gestalten, dass die Ständer- und Mahlwalzen-Schwinghebelkonstruktion sowie der Mahlteller beibehalten werden können und gleichzeitig ein ausreichender Ausbauraum für das Mühlengetriebe bzw. für die Mahlschüssellagerung und auch für den Ringkanal und die Gaskanäle unterhalb der Mahlschüssel vorhanden sind.A basic idea of the invention can be seen in designing the position of the oscillating lever axes with respect to the respectively associated stand in such a way that the stator and grinding roller oscillating lever construction as well as the grinding table can be maintained and, at the same time, sufficient installation space for the mill gear or for the mill gear Mahlschüssellagerung and also for the annular channel and the gas channels below the grinding bowl are present.
Für eine erfindungsgemäße Wälzmühle, beispielsweise eine 6-Walzenmühle, werden Mahlwalzen mit einer begrenzten Mahl- walzen-/Schwinghebelmasse und ein Mahlteller eingesetzt, welche beispielsweise von 4-Walzmühlen bekannt sind . Die Ständer können vorteilhafterweise ebenfalls den bekannten Ständern entsprechen. Ausgenommen ist die Anordnung der Schwinghebelachsen in oder an den Ständern.For a roller mill according to the invention, for example a 6-roller mill, grinding rollers with a limited grinding roller / oscillating lever mass and a grinding plate are used, which are known, for example, from 4-roller mills. The stands can advantageously also correspond to the known stands. Excluded is the arrangement of the rocker arm axes in or on the uprights.
Gemäß der Erfindung werden die Ständer zur Realisierung eines ausreichend großen Ausbauraumes für das Getriebe und eines ausreichenden Raumes für den Ringkanal und die Gas- kanäle der Gasströme in einem größeren radialen Abstand zur Mahlschüssel bzw. zum Mühlenzentrum angeordnet, die Lage der Schwinghebelachsen zur Mahlschüssel bzw. zum Mühlenzentrum wird jedoch nicht verändert .According to the invention, the stands are arranged to realize a sufficiently large installation space for the transmission and a sufficient space for the annular channel and the gas channels of the gas streams at a greater radial distance from the grinding bowl or to the mill center, the position of the rocker axes to the grinding bowl or but the mill center is not changed.
Bezogen auf den jeweils zugehörigen Ständer befindet sich die Schwinghebelachse in einer neuen Position. Die Schwinghebelachse ist nicht mehr wie bei den bekannten Wälzmühlen innerhalb des Ständerprofils, zum Beispiel auf der Längsachse der Ständer, angeordnet . Gemäß der Erfindung ist jede Schwinghebelachse außerhalb des Ständers ausgebildet und befindet sich, bezogen auf einen von den Ständern gebildeten Kreisring, radial innen in Richtung Mahlteller bzw. Mühlenzentrum.Based on the respectively associated stand, the oscillating lever axis is in a new position. The oscillating lever axis is no longer arranged as in the known roller mill within the stator profile, for example on the longitudinal axis of the stator. According to the invention, each oscillating lever axis is formed outside of the stator and is located, relative to a circular ring formed by the uprights, radially inward in the direction of the grinding table or mill center.
Die Anordnung der Schwinghebelachsen für die Mahlwalzen außerhalb der Ständer bedeutet gleichzeitig, dass die Schwinghebelachsen nicht mehr innerhalb der Grundrisse der Ständer vorgesehen sind .The arrangement of the rocker axles for the grinding rollers outside the stand means at the same time that the rocker axes are no longer provided within the floor plans of the stand.
Gemäß der Erfindung befindet sich somit die Schwinghebelachse nicht mehr auf der vertikalen Ständerachse, und die Ständer sind nicht mehr im Wesentlichen zylindrische Konstruktionen mit einem meist rechteckigen Querschnitt, sondern weisen einen oberen Bereich mit einem Lagerteil für die Schwinghebelachse auf, welches beispielsweise ein "abgeknickter" und in Richtung Mühlenzentrum weisender Bereich ist.According to the invention, therefore, the rocker shaft is no longer on the vertical column axis, and the stands are no longer substantially cylindrical structures with a generally rectangular cross-section, but have an upper portion with a bearing part for the rocker shaft, which for example, a "bent" and pointing towards the mill center area.
Gemäß der Erfindung kann das Lagerteil für die Schwinghebelachse in die Ständer integriert sein und mit diesen gefertigt werden, was beispielsweise bei Stahlständern vorteilhaft sein kann. Das Lagerteil ist dann ein in Richtung Mühlenzentrum auskragendes Teil , welches die Schwinghebelachse aufnimmt .According to the invention, the bearing part for the rocker arm axis can be integrated into the uprights and manufactured with them, which can be advantageous, for example, in the case of steel uprights. The bearing part is then a projecting towards the mill center part which receives the rocker arm axis.
Die Ständer können auch als Betonständer ausgebildet sein. Es empfiehlt sich dann, am oberen Bereich der Ständer einen Lagerbock als Gussteil anzuordnen und den Lagerbock mit einem nach radial innen in Richtung Mahlteller auskragenden Lagerteil zu versehen.The stand can also be designed as a concrete stand. It is then advisable to arrange a bearing block at the top of the stand as a casting and to provide the bearing block with a radially inwardly projecting towards grinding plate bearing part.
Die wesentlichen Vorteile der erfindungsgemäßen Wälzmühle bestehen darin, dass eine Steigerung der Nenn-Mahlleistung durch Anordnung von mehreren Mahlwalzen um einen Mahlteller erreicht werden kann, wobei die bekannte und bewährte Walzen-/Schwinghebelkonstruktion eingesetzt werden kann und auch der Mahlteller im Wesentlichen beibehalten werden kann. Indem nur die Ständer nach radial außen verlagert werden und die Anordnung bzw. Positionierung der Lagerung für die Schwinghebelachse der Ständer in Bezug auf das Mühlenzentrum bzw. den Mahlteller nicht verändert wird, sind relativ geringe Konstruktions- und Investitionskosten für Mühlen unterschiedlicher Mahlleistungen erforderlich.The main advantages of the roller mill according to the invention are that an increase in the nominal grinding capacity by arranging several grinding rollers around a grinding table can be achieved, the known and proven roller / rocker arm construction can be used and also the grinding table can be substantially maintained. By only the stands are displaced radially outward and the arrangement or positioning of the bearing for the oscillating lever axis of the stator with respect to the mill center or the grinding table is not changed, relatively low construction and investment costs for mills different grinding performance required.
Bei Verwendung eines Lagerbocks ist es zweckmäßig, ein Befestigungsteil vorzusehen, mit welchem der Lagerbock an dem Ständer befestigt werden kann, und daran das Lagerteil für die Schwinghebelachse anzuordnen. Beispielsweise kann das Lagerteil in Form von zwei voneinander beabstandeten Wangen ausgebildet sein.When using a bearing block, it is expedient to provide a fastening part, with which the bearing block can be attached to the stand, and to arrange the bearing part for the swing lever axis. For example, the bearing part may be in the form of two cheeks spaced apart from each other.
Bei der erfindungsgemäßen Ständer-Schwinghebelachsenkonstruktion können vorteilhaft Maßnahmen zur Versteifung vorgesehen werden. Beispielsweise können im oberen Bereich der Ständer und der radial nach innen versetzt angeordneten Schwinghebelachsen Zwischenelemente angeordnet werden, welche den Abstand zwischen den Ständern und Schwinghebelachsen ausfüllen und einen torsionssteifen Kranz oder Ring bilden.In the stator rocker arm axle construction according to the invention advantageous measures for stiffening can be provided. For example, in the upper region of the uprights and the radially inwardly staggered oscillating lever axes, intermediate elements can be arranged which fill the space between the uprights and oscillating lever axes and form a torsion-resistant rim or ring.
Die Zwischenelemente können von den radial außen liegendem Rand der Ständer oder auch der Lagerböcke bis zum Mühlengehäuse bzw. bis zum radial innen liegenden Ende des Lagerteils reichen und nahezu kreisringsegmentartig ausgebildet sein.The intermediate elements may extend from the radially outer edge of the stand or the bearing blocks to the mill housing or to the radially inner end of the bearing part and be formed almost circular ring segment-like.
Die Erfindung wird nachstehend anhand einer Zeichnung weiter erläutert; in dieser zeigen in einer stark schematisierten Weise Fig. 1 eine erfindungsgemäße Wälzmühle in Modulbauweise, jedoch ohne Mühlengehäuse und Sichter;The invention will be further explained below with reference to a drawing; in this show in a highly schematized way 1 shows a rolling mill according to the invention in modular design, but without mill housing and classifier.

In Fig . 1 ist eine perspektivische Ansicht einer Wälzmühle gezeigt, von der jedoch nur die im Rahmen der vorliegenden Erfindung wesentlichen Bauteile dargestellt sind . So wurde zur besseren Übersicht darauf verzichtet, das gesamte Mühlengehäuse mit integriertem Sichter darzustellen.In Fig. 1 is a perspective view of a roller mill, but only the components essential to the present invention are shown. For better clarity, it was decided not to display the entire mill housing with integrated sifter.
Bei der Wälzmühle gemäß Fig . 1 und 2 handelt es sich um eine 6-Walzenmühle in Modulbauweise . Es sind sechs Mahlwalzen 2 um einen rotierenden Mahlteller 3 angeordnet . Jede Mahlwalze 2 ist in einem Schwinghebel 4 geführt und um eine Schwinghebelachse 5 schwenkbar gelagert und über die Schwinghebelachse 5 auf einem Ständer 7 abgestützt .In the roller mill according to FIG. 1 and 2 is a modular 6-roller mill. There are six grinding rollers 2 arranged around a rotating grinding table 3. Each grinding roller 2 is guided in a rocking lever 4 and mounted pivotably about a rocking lever axis 5 and supported on a stand 7 via the rocking lever axis 5.
Zum Ausschwenken der Mahlwalzen 2 und des Schwinghebels 4 von der in Fig . 1 gezeigten Mahlstellung in eine aus dem Mühlengehäuse 16 herausgeschwenkten Stellung ( nicht dargestellt ) sind Öffnungen 17 in dem Mühlengehäuse 16 vorgesehen. Die Öffnungen 17 sind zur Ausbildung eines gasdichten Mühlengehäuses 16 mit entsprechenden Abdeckungen ( nicht dargestellt ) versehen. Jede Mahlwalze 2 mit Schwinghebel 4 und horizontaler Schwinghebelachse 5 weist eine hydropneumatische Federung 18 auf, welche mit dem Ständer 7 in einem Mühlenfundament ( nicht dargestellt ) verankert ist .For swinging the grinding rollers 2 and the rocker arm 4 of the in Fig. 1 shown in Fig. 1 in a swung out of the mill housing 16 position (not shown) openings 17 are provided in the mill housing 16. The openings 17 are provided to form a gas-tight mill housing 16 with corresponding covers (not shown). Each grinding roller 2 with rocker arm 4 and horizontal rocker shaft 5 has a hydropneumatic suspension 18, which is anchored to the stator 7 in a mill foundation (not shown).
Im Mühlenzentrum sind auf einem Getriebe-Fundament 19 das Getriebe 6 sowie der Mühlenantrieb angeordnet ( siehe auch Fig. 2 ) . Des Weiteren sind kastenförmige Gaskanäle 20 zwischen den Ständern 7 angeordnet, durch welche die erforderlichen Gasströme der Mühle zugeführt werden, um durch den Schaufelkranz ( nicht dargestellt ) am Umfang des Mahltellers 3 in den Mahlraum zu gelangen und das genügend zerkleinerte Mahlgut zum Sichter ( nicht dargestellt ) zu tragen.In the mill center, the transmission 6 and the mill drive are arranged on a transmission foundation 19 (see also FIG. 2). Furthermore, box-shaped gas channels 20 are arranged between the uprights 7, through which the required gas flows are fed to the mill (not shown) on the circumference of the grinding table 3 in the grinding chamber and the sufficiently comminuted millbase for classifier (not shown ) to wear.
Bei dem in Fig. 1 gezeigten Ausführungsbeispiel sind die Schwinghebelachsen 5 der Mahlwalzen 2 in einem Lagerbock 10 gelagert . Aus den vergrößerten Darstellungen eines Ständers 7 in den Fig. 3 bis 5 gehen Anordnung und Ausbildung des Lagerbocks 10 hervor . Gemäß der Erfindung liegt die Schwinghebelachse 5 nicht mehr oberhalb des Ständers 7 bzw. auf der Längsachse 14 des Ständers, sondern neben bzw. in einer radial nach innen in Richtung Mahlteller 3 versetzten Stellung.In the embodiment shown in Fig. 1, the rocker axes 5 of the grinding rollers 2 are mounted in a bearing block 10. From the enlarged representations of a stator 7 in FIGS. 3 to 5, arrangement and design of the bearing block 10 are apparent. According to the invention, the oscillating lever axis 5 is no longer above the stator 7 or on the longitudinal axis 14 of the stator, but next to or in a radially inwardly offset in the direction of the grinding table 3 position.
Am oberen Bereich der Ständer 7 ist der Lagerbock 10 mit einem Befestigungsteil 11 befestigt . Zu diesem Zweck weist das Befestigungsteil 11 eine komplementäre Ausbildung zum oberen Bereich der Ständer 7 auf . Seitlich am Befestigungsteil 11 und von diesem weggerichtet und schräg nach oben auskragend ist ein Lagerteil 12 in Form von zwei Wangen 13 vorgesehen, welche der Lagerung der Schwinghebelachse 5 dienen.At the upper region of the stator 7, the bearing block 10 is fastened with a fastening part 11. For this purpose, the fastening part 11 has a complementary design to the upper region of the uprights 7. Laterally on the fastening part 11 and directed away from this and projecting obliquely upwards, a bearing part 12 in the form of two cheeks 13 is provided, which serve for the mounting of the oscillating lever axis 5.
Indem die Schwinghebelachse 5 nicht mehr im Bereich der Ständer 7 , nämlich innerhalb des Grundrisses der Ständer 7 , sondern außerhalb und, in Betriebsstellung gemäß Fig. 1 gesehen, radial innen zwischen Ständer 7 und Mahlteller 3 angeordnet ist, wird eine Anordnung von mehr als vier Mahlwalzen-Ständer-Einheiten um einen Mahlteller 3 mit einem relativ geringem Aufwand möglich. Dabei können vorteilhaft Mahlwalzen 2 und Schwinghebel 4 mit begrenzten Walzen-/ Schwinghebelmassen und Mahlteller 3 von einer Mahlwalze mit weniger Mahlwalzen, insbesondere von einer 4-Walzenmühle, eingesetzt werden.By the swing lever axis 5 is no longer in the area of the stator 7, namely within the outline of the stator 7, but outside, and, seen in the operating position shown in FIG. 1, radially inwardly between the stator 7 and grinding plate 3 is arranged, an arrangement of more than four grinding roller stand units is possible around a grinding table 3 with a relatively low effort. In this case, grinding rollers 2 and rocker arm 4 with limited roller / rocker arm masses and grinding table 3 can advantageously be used by a grinding roller with fewer grinding rollers, in particular by a 4-roller mill.
Um den notwendigen Abstand zwischen den Ständern 7 für die erforderliche Anordnung von ausreichend dimensionierten Gaskanälen 20 und auch für die Montage und Demontage des im Zentrum der Mühle positionierten Getriebes 6 zu gewährleisten, sind die Ständer 7 im Vergleich zu einer 4-Walzenmüh- Ie nach außen verlagert . Um die Schwinghebelachse 5 in Bezug auf den Schwinghebel 4 und die Mahlwalze 2 sowie in Richtung Mühlenzentrum bzw. Mühlenachse nicht zu verändern, wurde die Position der Schwinghebelachse 5 in Bezug auf die Ständer 7 geändert . Bei den in den Figuren gezeigten Beispielen wird eine außermittige Anordnung der Schwinghebel- achse 5 bezogen auf die Ständer 7 durch eine entsprechende Ausbildung des separaten Lagerbocks 10 erreicht .In order to ensure the necessary distance between the uprights 7 for the required arrangement of sufficiently sized gas ducts 20 and also for the assembly and disassembly of the gear 6 positioned in the center of the mill, the uprights 7 are outwardly compared to a 4-roll mill relocated. In order not to change the rocking lever axis 5 with respect to the rocking lever 4 and the grinding roller 2 and towards the mill center or mill axis, the position of the rocking lever axis 5 with respect to the uprights 7 has been changed. In the examples shown in the figures, an eccentric arrangement of the oscillating lever axis 5 relative to the uprights 7 is achieved by a corresponding design of the separate bearing block 10.
Grundsätzlich besteht auch die Möglichkeit, das nach radial innen auskragende Lagerteil 12 mit der außerhalb der Ständer 7 anzuordnenden Schwinghebelachse 5 in die Ständer 7 zu integrieren. Beispielsweise kann dies bei Stahlständern durch einen entsprechend abgewinkelten oder abgebogenen oberen Bereich erreicht werden.In principle, it is also possible to integrate the radially outwardly projecting bearing part 12 with the outside of the stand 7 to be arranged rocking lever axis 5 in the stator 7. For example, this can be achieved in steel stands by a corresponding angled or bent upper portion.
Im oberen Bereich der Ständer 7 und zumindest an die Befestigungsteile 11 der Lagerböcke 10 angrenzend sind zur Versteifung und Ausbildung eines torsionssteifen Kranzes Zwischenelemente 15 angeordnet . In Fig . 2 ist in einer stark schematisierten Darstellung die Anordnung der Ständer 7 der Mühle gemäß Fig. 1 in ihrem unteren Bereich gezeigt . Indem das Getriebe 6 im Zentrum der Mühle mit einem Getriebefundament 19 dargestellt ist, wird deutlich, dass der erforderliche Ausbauraum 21 zwischen zwei benachbarten Ständern 7 vorhanden ist .In the upper region of the uprights 7 and at least adjacent to the fastening parts 11 of the bearing blocks 10, intermediate elements 15 are arranged to stiffen and form a torsionally rigid ring. In Fig. 2 is a highly schematic representation of the arrangement of the stator 7 of the mill shown in FIG. 1 in its lower region. By the gear 6 is shown in the center of the mill with a geared foundation 19, it is clear that the required expansion space 21 between two adjacent uprights 7 is present.
In den Fig . 3 bis 5 sind die in Fig . 1 gezeigten Ständer 7 vergrößert gezeigt . Sie verdeutlichen die außermittige bzw. außerhalb des Grundrisses der Ständer 7 positionierte Schwinghebelachse 5. Durch diese Ausbildung bzw. Positionierung der Schwinghebelachse 5 zwischen dem Mahlteller 3 bzw. dem Mühlengehäuse 16 und dem jeweiligen Ständer 7 wird ohne wesentliche Änderung des Mahltellers 3 , der Mahlwalzen 2 mit Schwinghebel 4 und der unteren Bereiche der Ständer 7 erreicht, dass mehr Mahlwalzen 2, insbesondere sechs Mahlwalzen 2 angeordnet werden können und eine erhöhte Mühlenleistung erreicht werden kann. In the Figs. 3 to 5 are the in Fig. 1 shown stand 7 shown enlarged. They illustrate the eccentric or outside the outline of the stator 7 positioned oscillating lever axis 5. This training or positioning of the oscillating lever axis 5 between the grinding table 3 and the mill housing 16 and the respective stator 7 is without substantial change of the grinding table 3, the grinding rollers. 2 achieved with rocker arm 4 and the lower portions of the stator 7 that more grinding rollers 2, in particular six grinding rollers 2 can be arranged and increased mill performance can be achieved.
