Description
Den Gegenstand der vorliegenden Erfindung bildet eine Ringmühle.The subject of the present invention is a ring mill.
Der Erfindungsgegenstand unterscheidet sich von den bekanntgewordenen Konstruk-S tionen dadurch, daß das Gehäuse für den Mahlring, in dem eine Mahlwalze exzentrisch gelagert ist, um einen festen Punkt des Mühlengestells verschwenkt werden kann.The subject of the invention differs from the known Konstruk-S functions in that the housing for the grinding ring, in which a grinding roller is eccentric is mounted to be pivoted about a fixed point of the mill frame.
Aus der Zeichnung ist die Wirkungsweise ίο der Mühle zu entnehmen.The operating principle ίο of the mill can be seen in the drawing.
Wird bei g Mahlgut zugeführt, dann wird es durch die sich in der Pfeilrichtung drehende
Mahlwalze α mitgerissen und zwischen Walze α und Mahlring b gequetscht.
Der Mahlring & ist im Ringgehäuse c mit geringer Reibung, etwa auf Kugeln, gelagert
und kann deshalb, durch die Reibung des Mahlgutes an der Innenwand mitgenommen, eine gleiche Umfangsgeschwindigkeit wie die
Walze α annehmen.Is supplied at g ground material, it is α entrained by the rotating grinding roll in the direction of arrow α and between the roller and the grinding ring b squeezed.
The grinding ring & is mounted in the ring housing c with low friction, for example on balls, and can therefore assume the same circumferential speed as the roller α , being carried along by the friction of the grinding material on the inner wall.
Beim Schroten wird eine Bremsvorrichtung/1 benutzt, um die Drehzahl des Mahlringes herabzusetzen, so daß ein Geschwindigkeitsunterschied zwischen den Mahlfiäohen entsteht und das Mahlgut zerrissen wird.When grinding, a braking device / 1 is used to reduce the speed of the grinding ring, so that a difference in speed between the grinding lines is created and the material to be ground is torn.
Beim Mahlen, also bei Erzielung größerer Feinheit, wird der Mahlring b durch die Bremse/ vollständig zum Stillstand gebracht und das Mahlgut zwischen einer feststehenden und einer sich bewegenden Fläche zermahlen. Durch eine Stellvorrichtung h wird das Gehäuse c mit dem Ring b um den Punkt d geschwenkt. Auf diese Weise hat man 'die Möglichkeit, die Entfernung zwischen dem Ring b und der Walze α in der Mahlstelle zu verändern und damit den Feinheitsgrad des Mahlgutes beliebig zu beeinflussen. Damit die Stellvorrichtung elastisch wirkt, ist eine Feder i eingeschaltet.When grinding, i.e. when achieving greater fineness, the grinding ring b is brought to a complete standstill by the brake / and the material to be ground is ground between a stationary and a moving surface. The housing c with the ring b is pivoted about the point d by an adjusting device h. In this way one has the possibility of changing the distance between the ring b and the roller α in the grinding point and thus influencing the degree of fineness of the ground material as desired. A spring i is switched on so that the adjusting device has an elastic effect.
Ein verstellbares Widerlager, etwa in Form einer Stellschraube k, verhindert bei der Schwenkung des Mahlringes b, daß der Mahlring mit der Mahlwalze in Berührung kommt. Dabei legt sich das Gehäuse c gegen den Bolzen k, und da der Ring b im Gehäuse c gelagert ist, so wird auch der Druck der Stellvorrichtung h von der Schraube k aufgefangen. Deshalb ist bei richtiger Einstellung der Stellschraube k eine Berührung der Mahlwalze α mit dem Mahlring b ausgeschlossen.An adjustable abutment, for example in the form of an adjusting screw k, prevents the grinding ring b from coming into contact with the grinding roller when the grinding ring b is pivoted. The housing c rests against the bolt k, and since the ring b is mounted in the housing c , the pressure of the adjusting device h is also absorbed by the screw k. Therefore, if the adjusting screw k is set correctly, contact of the grinding roller α with the grinding ring b is ruled out.
