Description

Maschinen zum Zerkleinern von anorganischen und organischen Stoffen sind in verschiedener Form und Wirkungsweise bekannt. In den Schlagkreuzmühlen geschieht beispielsweise die Zerkleinerung des eingebrachten Gutes durch hammerschkgar,tige Einwirkung, während bei den Reibmaschinen das zu zerkleinernde Gut zwischen zusammengepreßten Walzen, die mit verschiedenen Geschwindigkeiten umlaufen, zerrieben wird.Machines for crushing inorganic and organic materials are of various shapes and sizes Known mode of action. In the cross beater mills, for example, what is introduced is crushed Good things through hammered action, while in the case of graters, that which is to be crushed Well rubbed between compressed rollers rotating at different speeds.

Es sind weiterhin Schrotwalzen bzw. Walzenbrecher bekannt, bei denen als Zerkleinerungswerkzeuge wellen- oder kurvenförmige Sägeblätter oder ein Grobwalzenpaar mit großen Zähnen und anschließend ein Feinwalzenpaar mit kürzeren Zähnen angeordnet sind. In diesen Fällen sind aber jeweils nur zwei verzahnte Walzen oder Wellen mit kurvenförmigen Sägeblättern angebracht, die ineinandergreifen, um vermittels dieses Eingriffes die eingebrachten Stoffe durch schneidende und mahlende Wirkung zu zerkleinern. Infolge dieser Wirkungsweise erfordert die Verarbeitung langfaseriger Stoffe, insbesondere diejenige von Holzspänen und Holzabfällen zu Mehl, eine verhältnismäßig lange Zeitdauer mit beträchtlichem Energieaufwand, so daß die Herstellung von Mehl aus solchen Stoffen in diesen Einrichtungen unwirtschaftlich wird.There are also known shot rolls or roll crushers in which wave-shaped or curved saw blades or a pair of coarse rolls with large teeth and then a pair of fine rolls with shorter teeth are arranged as comminuting tools. In these cases, however, only two toothed rollers or shafts with curved saw blades are attached, which mesh with one another in order to crush the introduced substances by cutting and grinding action by means of this engagement. As a result of this mode of action, the processing of long-fiber materials, in particular that of wood chips and wood waste into flour, requires a relatively long period of time with considerable expenditure of energy, so that the production of flour from such materials in these facilities is uneconomical.

Dieser Nachteil wird gemäß der Erfindung dadurch vermieden, daß die auf Lücke angeordneten Zerkleinerungsrotoren derart unter- und nebeneinander angeordnet sind, daß sämtliche in einer Ebene liegenden Verbindungslinien der einzelnen Rotorachsen gleichseitige Dreiecke bilden.This disadvantage is avoided according to the invention in that the comminuting rotors arranged in a gap are arranged one below the other and next to one another that all lying in one plane Form connecting lines of the individual rotor axes equilateral triangles.

In der Zeichnung ist das Prinzip der Erfindung schematisch dargestellt.The principle of the invention is shown schematically in the drawing.

In einem Gehäuse α mit dem Einfülltrichter b und dem Auslauftrichter c sind Zerkleinerungsrotoren angeordnet, die jeweils aus den Zahnscheiben d und e sowie der Rotorachse/ bestehen. Die Zerkleinerungsrotoren d, e und f sind derart unter- und nebeneinander angeordnet, daß die in einer Ebene liegenden Verbindungslinien zwischen den Mittellinien der einzelnen Rotorachsen f gleichseitige Dreiecke bilden. Die Zahnscheiben e, die gleichzeitig als Distanzringe dienen, weisen einen kleineren Durchmesser als die Zahnscheiben d auf, welche auf einer Teilstrecke ihres Umfanges in Lücken g eingreifen.In a housing α with the filling funnel b and the discharge funnel c , shredding rotors are arranged, each consisting of the toothed disks d and e and the rotor axis /. The shredding rotors d, e and f are arranged one below the other and next to one another in such a way that the connecting lines lying in one plane between the center lines of the individual rotor axes f form equilateral triangles. The toothed disks e, which also serve as spacer rings, have a smaller diameter than the toothed disks d , which engage in gaps g over a section of their circumference.

Als Zahnscheiben d und e kommen gewöhnliche Kreissägeblätter in Frage, die je nach der Art des Zerkleinerungsgutes oder den sonstigen Erfordernissen mit Hartmetall bestückt sein können oder auch aus nichtstählernem Werkstoff bestehen. Je nach Größe des einlaufenden Zerkleinerungsgutes können die Zahnscheiben d und e auf den Rotorachsen f als einzelne Sägeblätter oder in zwei- oder mehrfacher Schichtung angebracht werden.As toothed disks d and e , conventional circular saw blades come into question, which, depending on the type of material to be shredded or the other requirements, can be equipped with hard metal or also consist of non-steel material. Depending on the size of the incoming material to be shredded, the toothed disks d and e can be attached to the rotor axes f as individual saw blades or in two or more layers.

Die Drehrichtung und die Drehzahl der Zerkleinerungsrotoren d, e, f ist untereinander verschieden, und zwar ist die Drehzahl gegenüber bisher bekannten rotierenden Maschinen zur Herstellung von pulverförmigen Gutes so hoch, daß innerhalb des Gehäuses α ein starker Sog entsteht. Hierdurch und durch die gleichzeitig auf das Zerkleinerungsgut einwirkende Zentrifugalkraft wird dasselbe mit großer Wucht auf die Zähne der Zahnscheiben d und e geschleudert, so daß in kurzer Zeit bei geringem Energieaufwand eine Zertrümmerung des Gutes bis zu pulverförmiger Feinheit erfolgt.The direction of rotation and the speed of the comminuting rotors d, e, f are different from each other, namely the speed is so high compared to previously known rotating machines for the production of powdery goods that a strong suction occurs within the housing α. As a result of this and the centrifugal force acting simultaneously on the material to be shredded, it is thrown with great force onto the teeth of toothed disks d and e , so that the material is broken up to powdery fineness in a short time with little energy consumption.
