Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Maschine besteht aus einejn Walzenpaare α und b (Fig. 1 und 2), von welchen die eine, hier beispielsweise a, durch das Zahnrad c, Vorgelege d und Riemscheibe e in Bewegung gesetzt wird und die zweite Walze b durch die, nachstehend beschriebenen Zähne direct mitbewegt.The machine consists of a pair of rollers α and b (Figs. 1 and 2), one of which, here for example a, is set in motion by the gear wheel c, back gear d and pulley e and the second roller b by those described below Teeth moved directly with it.
Das zu zerkleinernde Material wird auf der ganzen Walzenlänge durch den Trichter g auf die Walzen gebracht. Die Walzen, deren eine α festgelagert ist, werden durch die Federn f, welche auf die beweglichen Lager der Walze b drücken, je nach Bedarf kräftig gegen einander geprefst.The material to be comminuted is brought onto the rollers through the funnel g over the entire length of the roller. The rollers, one of which is fixedly mounted α are f by the springs, which press the movable bearing of the roller b, geprefst firmly against each other as required.
Ueber die ganze Walzenlänge sind nun Zähne angeordnet, deren Form bewirkt, dafs bei der Umdrehung um eine viertel Theilung die bewegliche Walze sich der festen Walze einmal nähert und entfernt, wie aus den Fig. 3, 4 und 5 ersichtlich.Teeth are now arranged over the entire length of the roller, the shape of which means that when turning a quarter of a division, the movable roller joins the fixed roller approaches and removes once, as can be seen from FIGS. 3, 4 and 5.
Fig. 3 zeigt die Zähne in der Stellung, in welcher das Zahnmittel und die beiden Walzenmittel in einer Ebene liegen. Walze α ist fest gelagert, während die Lager der Walze b sich horizontal verschieben können.Fig. 3 shows the teeth in the position in which the tooth means and the two roller means lie in one plane. Roll α is fixed, while the bearings of the roll b can move horizontally.
Man denke sich nun zunächst das Mittel der Walze b ebenfalls fort und beide Walzen um eine viertel Theilung in der Pfeilrichtung gedreht, so wird nach Fig. 4 ersichtlich, dafs zwischen der Kopfflanke h und der Grundflanke i der Zwischenraum h i entsteht, ebenso bei der anderen Kopfflanke k und Grundflanke / der Zwischenraum k I. Imagine now the center of the roller b and both rollers rotated a quarter of a division in the direction of the arrow, so it can be seen from Fig. 4 that the gap hi arises between the top flank h and the base flank i , as is the case with the other Head flank k and base flank / the space k I.
Da aber das Mittel der Walze b durch Kraftwirkung an das Mittel der Walze a herarigeprefst wird und die Zähne gegenseitig kein Hindernifs bilden, so wird die Walze b gegen die Walze α so weit herangeschoben, als es die Lücken gestatten, d. h. bis dieselben durch die gegenseitigen Zähne ausgefüllt sind, wie es Fig. 5 veranschaulicht, indem das Mittel m der Walze b nach η verschoben worden ist. Bei einer weiteren Drehung um eine viertel Theilung rückt das Mittel wieder von η nach m; diese horizontale Bewegung, welche während der Drehung stattfindet, äufsert sich auf den Zahnflanken als Reibung, so dafs das sich zwischen den Zähnen befindende Arbeitsgut nicht nur zerdrückt wird, sondern auch einer Zerreibung unterworfen ist, wobei dieser Procefs bei einer Drehung um eine Theilung vier Mal stattfindet, dadurch, dafs die Walze b sich der Walze α zwei Mal nähert und entfernt.But since the center of the roller b is pressed against the center of the roller a by force and the teeth do not form an obstacle to one another, the roller b is pushed against the roller α as far as the gaps allow, that is, until the same through the mutual Teeth are filled, as Fig. 5 illustrates, in that the center m of the roller b has been shifted to η. With a further rotation by a quarter of a division the mean shifts again from η to m ; This horizontal movement, which takes place during the rotation, manifests itself as friction on the tooth flanks, so that the material to be worked between the teeth is not only crushed, but is also subjected to attrition, this process four times with a rotation of one division takes place, in that the roller b approaches the roller α two times and moves away from it.
