Description

Rollenquetschmühle Zusatz zum Patent 935169 Die Erfindung bezieht sich auf Rollenquetschmühlen, die auch häufig als Ringwalzenmühlen bezeichnet werden, bei denen also die Mahlkörper (Rollen bzw. Walzen) zwischen einem rotierenden Mahlteller und einem im Mahlgehäuse ortsfest gelagerten Druckring abrollen. Mittels Federkraft wird der erforderliche Mahldruck vom Druckring über die Mahlrollen zum Mahlgut geleitet, wobei während des Abrollvorganges die Zerkleinerung des Mahlgutes erfolgt.Roller mill addendum to patent 935169 The invention relates on roller mills, which are also often referred to as ring roller mills, So in which the grinding media (rollers or cylinders) between a rotating grinding table and roll off a pressure ring that is fixedly mounted in the grinder housing. By means of spring force the required grinding pressure is directed from the pressure ring via the grinding rollers to the grist, whereby the grinding material is comminuted during the unrolling process.

Gemäß dem Hauptpatent 935169 sind die Mahlrollen mit seitlichen Ansätzen versehen, die auf dem Druckring ablaufen. Gemäß der Erfindung wird nun eine derart ausgebildete Rollenquetschmühle noch dadurch verbessert, daß die Ansätze der Mahlkörper eine konvexe, rotationssymmetrische Form aufweisen und der Druckring auf seiner Unterseite entsprechend konkav ausgebildet ist.According to the main patent 935169, the grinding rollers are with lateral approaches provided that run on the pressure ring. According to the invention, one is now such trained roller mill improved by the fact that the approaches of the grinding media have a convex, rotationally symmetrical shape and the pressure ring on its Underside is correspondingly concave.

Der Vorteil dieser Formgebung an Druckring und Ansatz besteht darin, daß eine sehr weitgehende pendelnde Bewegung des Mahlrollensystems erfolgen kann, und außerdem können optimale Druckverhältnisse an den Berührungsflächen - abgestimmt auf die Neigung der Mahlrollen - eingestellt werden.The advantage of this design on the pressure ring and attachment is that that a very extensive oscillating movement of the grinding roller system can take place, and in addition, optimal pressure conditions on the contact surfaces can be coordinated to the inclination of the grinding rollers - can be adjusted.

Ein weiterer Vorteil dieser Ausführungsform ist darin zu sehen, daß die nach abwärts gerichtete konkave Form des Druckringes eine Staubansammlung zwischen den Berührungsflächen weitgehend verhindert, was sich günstig auf die Lebensdauer dieser Teile auswirkt.Another advantage of this embodiment can be seen in the fact that the downward concave shape of the pressure ring creates an accumulation of dust between the contact surfaces largely prevented, which has a positive effect on the service life affects these parts.

Es sind zwar auch noch andere Ausführungsformen von Mahlrollenansätzen bekannt, bei denen die pendelnde Beweglichkeit der Mahlrolle um einen Punkt oberhalb der Mahlbahn berücksichtigt ist, damit sich die Mahlrolle zum Mahlgut in der Mahlbahn beliebig einstellen kann. Da diese bekannte Ausführungsform der Rollenansätze eine nahezu konkave Form aufweist, kann zwischen den Rollenansätzen und dem Druckring leicht Staub eindringen, was einen raschen Verschleiß dieser Teile zur Folge hat. Es sind aber auch schon Rollenquetschmühlen bekannt, bei denen der Druckring auf seiner Unterseite mit einer konkaven Ringrille versehen ist, in der jedoch, im Gegensatz zum Erfindungsgegenstand, die Mahlkörper selbst abrollen.There are also other embodiments of grinding roller approaches known, in which the oscillating mobility of the grinding roller to a point above the grinding path is taken into account so that the grinding roller to the ground material in the grinding path can be set at will. Since this known embodiment of the role approaches a has an almost concave shape, can between the roller lugs and the pressure ring dust can easily penetrate, which causes these parts to wear out quickly. But there are already roller mills known in which the pressure ring is on its underside is provided with a concave annular groove, in which, however, in contrast the subject of the invention, roll the grinding media themselves.

PATENTANSPRUCH: Rollenquetschmühle, deren Mahlkörper durch einen unter Federdruck stehenden Ring gegen die Mahlbahn gepreßt werden, wobei an den Mahlkörpern als Rotationskörper ausgebildete Ansätze vorgesehen sind, die auf dem Druckring unter Übernahme des Mahldruckes abrollen, nach Patent 935169, dadurch gekennzeichnet, daß die Ansätze der Mahlkörper eine konvexe, rotationssymmetrische Form aufweisen und der Druckring auf seiner Unterseite entsprechend konkav ausgebildet ist. In Betracht gezogene Druckschriften: Deutsche Patentschrift Nr. 854 457.PATENT CLAIM: Roller squeegee mill, the grinding media of which is controlled by a Spring-loaded ring are pressed against the grinding track, with the grinding media lugs designed as rotational bodies are provided, which are mounted on the pressure ring roll while taking over the grinding pressure, according to patent 935169, characterized that the approaches of the grinding media have a convex, rotationally symmetrical shape and the pressure ring is correspondingly concave on its underside. In Publications considered: German Patent No. 854 457.
