Description
Die Erfindung betrifft einen Einwalzenbrecher zum Zerkleinein von Festkörpern mit einer drehbar gelagerten, drehangetriebenen Walze und mit einer ihr zugeordneten Schwinge als Zerkleinerungswerkzeuge, wobei wenigstens die der Schwinge zugekehrte Fläche der Walze profiliert ist, wobei die Profilierung, die durch Rippen und zwischen diesen angeordnete Nuten gebildet ist, wenigstens bereichsweise zur Richtung der Relativbewegung zwischen Walze und Schwinge geneigt ist.The invention relates to a single roller crusher for crushing solids with a rotatable mounted, rotatably driven roller and with a swing arm assigned to it as crushing tools, wherein at least the surface of the roller facing the rocker is profiled, wherein the profile, which is formed by ribs and grooves arranged between them, at least is inclined in regions to the direction of the relative movement between roller and rocker.
Bei den bekannten Zerkleinerungsvorrichtungen ergeben sich oft Probleme, da das zerkleinerte Gut eine langgestreckte Kornform besitzt, die in vielen Anwenwendungsfällen weniger gut geeignet ist als eine angenähert kubische Form des Korns. d.h. eine Form dem Korns, die keine besonders ausgeprägte Längenerstreckung in einer Richtung besitzt.Problems often arise in the known shredding devices, since the shredded material has an elongated grain shape that is less suitable than in many applications an approximately cubic shape of the grain. i.e. a shape of the grain that is not particularly pronounced Has length extension in one direction.
Aus der EP 0 563 564 A2 ist eine Walzenmühle bekannt. Die bekannte Walzenmühle zur Zerkleinerung von sprödem Mahlgut besitzt zwei gegensinnig umlaufende, mit hohem Druck gegeneinander gepreßte Mahlwalzen, die je einen Oberflächenprofilierungen aufweisenden Walzenmantel aus verschleißfestem Hartguß aufweisen. Damit die Walzen ein besonders gutes Einzugsvermögen und eine hohe Verschleißfestigkeit aufweisen, sind auf die Oberfläche des Walzenmantels Profilierungen in Form von Schweißraupen aus verschleißfestem Auftragschweißwerkstoff aufgebracht.A roller mill is known from EP 0 563 564 A2. The well-known roller mill for shredding von brittle regrind has two counter-rotating, high pressure against each other pressed grinding rollers, each with a surface profile roller shell have wear-resistant chilled cast iron. So that the rollers have a particularly good pulling capacity and have a high wear resistance, are profiles on the surface of the roll shell applied in the form of welding beads made of wear-resistant build-up welding material.
Der Erfindung liegt die Aufgabe zugrunde, einen insbsondere zur Feinzerkleinerung geeigneten Einwalzenbrecher der eingangs genannten Gattung anzugeben. mit dem unter guter Ausnutzung der Energie übenwiegend zerkleinertes Gut mit einer Kornform erhalten wird, die angenähert kubisch oder kugelförmig ist, also keine in einer Richtung besonders ausgeprägte Längenerstreckung hat.The invention has for its object a particularly suitable for fine grinding Single-roll crusher of the type mentioned above. with the under good use of the Energy mostly crushed material is obtained with a grain shape that is approximately cubic or is spherical, that is, it does not have a length extension that is particularly pronounced in one direction.
Erfindungsgemäß wird dies dadurch erreicht, daß die Profilierung der Walze und gegebenenfalls die der Schwinge durch in sie eingesetzte Körper aus Hartwerkstoff gebildet ist und daß die Walze aus mehreren in Achsrichtung nebeneinander angeordneten Scheiben besteht, wobei jede Scheibe an ihrem Umfang Rippen und Nuten zur Bildung der Profilierung aufweist.According to the invention this is achieved in that the profiling of the roller and, if necessary, the the rocker arm is formed by a body made of hard material and the roller is made of there are several disks arranged side by side in the axial direction, with each disk on has circumferential ribs and grooves to form the profile.
Mit der erfindungsgemäßen Vorrichtung wird eine besonders günstige Ausnutzung der für das Herbeiführen der Relativbewegung zwischen den Werkzeugßflächen (Schwinge-Walze) aufgewendeten Energie und eine überwiegend spaltende Zerkleinerung unter Ausnützung der geringen Zugfestigkeit der Mineralkörner erreicht und ein gewünschtes Korn mit angenähert "kubischer" Gestalt erzielt.With the device according to the invention a particularly favorable exploitation of the for Inducing the relative movement between the tool surfaces (rocker roller) Energy and a predominantly splitting shredding using the small Tensile strength of the mineral grains is achieved and a desired grain with approximately "cubic" Shaped.
Bei der Erfindung wird der gewünschte Effekt erreicht, weil durch die besonders strukturierte Oberfläche wenigstens der Walze, die eines der beiden die Zerkleinerung bewirkenden Werkzeuge ist, eine solche Wechselwirkung entsteht, daß nicht nur eine Bewegung der zu zerkleinernden Feststoffkörner senkrecht zur bewegten Walze entsteht, sondern auch eine Bewegungskomponente senkrecht zur Bewegungsrichtung der Relativbewegung auftritt. Die Bewegungskomponente wird beim erfindungsgemäßen Einwalzenbrecher durch die Strukturierung (Profilierung) der Oberfläche der Walze und bevorzugt auch eine solche der Schwinge erreicht. Diese Bewegungskomponente quer zur Bewegungsrichtung der Walze führt zur querrollenden Bewegung der Körner im Brechraum und damit zu einer Rundung derselben. Dadurch wird die Kornform im wesentlichen in Richtung Kubizität verbessert und damit der Nachteil der oben erwähnten, bekannten Zerkleinerungsvorrichtung vermieden.In the invention, the desired effect is achieved because of the particularly structured Surface of at least the roller, which is one of the two tools causing the comminution is such an interaction that not only a movement of the shredded Solid grains are created perpendicular to the moving roller, but also a movement component occurs perpendicular to the direction of movement of the relative movement. The movement component is in the single-roll crusher according to the invention by structuring (profiling) the surface the roller and preferably also one of the rocker. This movement component transverse to the direction of movement of the roller leads to the rolling movement of the grains in the crushing chamber and thus to round it off. This essentially turns the grain shape into Direction cubicity improved and thus the disadvantage of the above-mentioned known shredding device avoided.
Bevorzugte und vorteilhafte Ausführungsformen der erfindungsgemäßen Vorrichtung sind Gegenstand der Unteransprüche.Preferred and advantageous embodiments of the device according to the invention are the subject matter of subclaims.
Die Winkel der Profilierung zur Richtung der Relativbewegung zwischen der Walze und der Schwinge können je nach den Eigenschaften des zu zerkleinernden Werkstoffes gewählt und unter Berücksichtigung der übrigen Betriebsbedingungen des Einwalzenbrechers festgelegt werden. Bevorzugt ist dabei im Rahmen der Erfindung, daß die Profilierung der Walze und/oder die der Schwinge in Abschnitte mit entgegengesetzter Ausrichtung zur Richtung der Relativbewegung zwischen Walze und Schwinge unterteilt ist. Dabei kann vorgesehen sein, daß die Profilierung in den verschiedenen Abschnitten mit der Richtung der Relativbewegung zwischen Walze und Schwinge gleich große, jedoch entgegengesetzte Winkel einschließt. In bestimmten Anwendungsfällen bewährt sich eine Ausführungsform, bei der die Profilierung in den verschiedenen Abschnitten mit der Richtung der Relativbewegung zwischen Walze und Schwinge verschieden große und entgegengesetzte Winkel einschließt.The angle of the profiling to the direction of the relative movement between the roller and the Swing arms can be selected depending on the properties of the material to be shredded and under Taking into account the other operating conditions of the single roller crusher. It is preferred in the context of the invention that the profiling of the roller and / or that of Swing into sections opposite to the direction of relative movement is divided between roller and rocker. It can be provided that the profiling in the different sections with the direction of the relative movement between roller and Swing arm encloses equally large, but opposite angles. In certain applications an embodiment in which the profiling in the different sections has proven itself with the direction of the relative movement between roller and swing arm of different sizes and includes opposite angles.
In der Praxis kann die Profilierung der Walze und gegebenenfalls die der Schwinge quer zur Richtung der Relativbewegung zwischen Walze und Schwinge gesehen zickzack-förmig oder schlangenlinienförmig verlaufen.In practice, the profiling of the roller and possibly that of the rocker can be transverse to Direction of the relative movement between roller and rocker seen zigzag or run serpentine.
All diese bevorzugten Ausgestaltungsmöglichkeiten verbessern die Wirkung des erfindungsgemäßen Einwalzenbrechers, weil das Zerkleinern von Mineralstoffen oder anderen Feststoffen mit einem sehr engen Produktkornband verbessert, der Feinstkornanteil weiter minimiert, und eine günstigere Energieverwertung und ein besseres Ausbringen gewährleistet wird. Es versteht sich, daß die gute Kornform der Produkte auch über eine mehrstufige Ausführung oder eine Zwillingsausführung bei geringer Bauhöhe und entsprechender Durchsatzleistung möglich ist. All of these preferred design options improve the effect of the invention Single roller crusher, because the crushing of minerals or other solids with one very narrow product grain belt improved, the fine grain fraction further minimized, and a cheaper one Energy recovery and better output is guaranteed. It is understood that the good Grain shape of the products also in a multi-stage version or a twin version low height and corresponding throughput is possible.

1) entgegengesetzt gerichtete Winkel einschließen. Diese Winkel sind im gezeigten Ausführungsbeispiel
gleich groß und schließen bei Blickrichtung gemäß Fig. 2 mit der Achse 3 einen Winkel

verlaufen. 2, the
Auch die in die Schwinge 2 eingesetzten Werkzeugkörper 11 tragen auf ihrer der Walze 1 zugekehrten
Wirkfläche eine Strukturierung, die sich aus Rippen oder Schneiden 13 und dazwischen

(Pfeil 10) zwischen Walze 1 und Schwinge 2 gesehen die gleiche Breite wie die Abschnitte 7 und
8 der Rippen 5 an der Walze 1 haben.The
Im gezeigten Ausführungsbeispiel sind die Rippen 5 und die Nuten 6 der Walze 1 breiter als die

Relativbewegung zwischen Walze 1 und Schwinge 2 parallel verlaufen.The
In bestimmten Anwendungsfällen sind auch gebogene Rippen 5 bzw. 13 vorteilhaft. In bestimmten
Anwendungsfällen kann eine ungleichmäßige Verteilung der Rippen 5 und Nuten 6 auf der Walze
1 und/oder der Rippen 13 und der Nuten 14 an der Schwinge 2 bessere Ergebnisse bringen.In certain applications,

Die Rippen 5 und die Rippen 13 sind dadurch gebildet, daß in die Scheiben 4 der Walze 1 und in
die Schwinge 2 bzw. deren Werkzeugkörper 11 Leisten aus Hartstoff eingesetzt sind. Dabei besteht
die Möglichkeit, die verschiedenen Strukturelemente (also die Rippen 5 bzw. 13 einerseits und den
Trägerwerkstoff anderseits) aus unterschiedlichen Materialien zu bilden, so daß sich ein selbst
nachschärfender Effekt ergibt.The
Die Größe der Winkel α und β wird in Abhängigkeit von den Eigenschaften des zu zerkleinernden
Materials gewählt. So bewähren sich bei einen, Durchmesser der Walze 1 von 300 bis 800 mm und
