Bei den bekannten Systemen von Steinbrechern bilden die beiden Brechbacken einen bestimmten Winkel miteinander, der einerseits bedingt ist durch die Spaltweite, andererseits durch die Anforderung, möglichst große Stücke fassen zu können. In vielen Fällen ist dieser Winkel so groß, daß Materialien mit schlüpfriger Oberfläche, wie Bisulfat und ähnliche Salze usw., der Brechwirkung ganz ausweichenIn the known systems of stone crushers, the two crushing jaws form one certain angle with each other, which on the one hand is due to the gap width, on the other hand due to the requirement to be able to hold pieces as large as possible. In many cases this is Angle so large that materials with a slippery surface such as bisulphate and the like Salts, etc., to avoid the emetic effect entirely

ίο und im Brechmaul auf und nieder gehen, anstatt zertrümmert zu werden. Um überhaupt eine Brechwirkung zu erzielen, d. h. um den fraglichen Winkel klein genug zu machen, müßte man Brechbacken von sehr großer Länge herstellen, was praktisch meist nicht durchführbar ist.ίο and go up and down in the jaw instead of to be smashed In order to achieve a refractive effect at all, i. H. to make the angle in question small enough you would have to make crusher jaws of very great length, which is usually not practical is feasible.

Zweck der vorliegenden Erfindung ist, mit jedem Steinbrecher von normaler Backenlänge, bei enger Spaltweite und großer Maulweite, Materialien mit oben erwähnten Eigenschaften verarbeiten zu können. Es wird dies erreicht dadurch, daß eine oder beide Brechbacken in bekannter Weise Abstufungen erhalten, jedoch in der Art, daß die Oberflächen der einzelnen miteinander arbeitenden Abstufungen parallel oder möglichst parallel zueinander stehen, wobei die Höhe jeder einzelnen Abstufung geringer ist als der die Bruchwirkung erzeugende Hub der Brechbacken an den betreffenden Stellen.The purpose of the present invention is, with every stone crusher of normal jaw length, with narrow gap widths and large mouth widths, materials with the properties mentioned above to be able to process. This is achieved by having one or both jaws in is known to receive gradations, but in such a way that the surfaces of the individual working together gradations are parallel or as parallel as possible to each other, wherein the height of each individual gradation is less than that producing the fracture effect Stroke of the crushing jaws at the relevant points.

In der beiliegenden Zeichnung stellen Fig. 1 und 2 ein Paar Brechbacken dar, von welchen eine Backe, und zwar einmal die bewegliche und,einmal die stillstehende Backe, in der erwähnten Weise ausgeführt ist. In Fig. 3 sind beide Backen als Stufenbacken gedacht. Die Höhen der Abstufungen A1, A2, A3 ... sind geringer als der Hub der Brechbacke an der betreffenden Stelle, so daß das zu brechende Stück bei engster Stellung der Backen an jeder Stelle so weit zusammengedrückt ist, daß es anstandslos bei weitester Stellung der Backen in die nächste Abteilung des Brechmauls fallen kann. Die Längen der einzelnen Abstufungen I1, I2, I3 . . . werden der Reduktion der Stückgröße entsprechend nach unten hin ebenfalls kleiner gewählt.In the accompanying drawing, FIGS. 1 and 2 show a pair of crushing jaws, one jaw, namely the movable jaw and the stationary jaw, is designed in the manner mentioned. In Fig. 3, both jaws are intended as step jaws. The heights of the gradations A 1 , A 2 , A 3 ... are less than the stroke of the breaking jaw at the point concerned, so that the piece to be broken is compressed so far with the narrowest position of the jaws at each point that it is without objection furthest position of the jaws can fall into the next division of the crushing mouth. The lengths of the individual gradations I 1 , I 2 , I 3 . . . are also chosen to be smaller in accordance with the reduction in the piece size.

Die vorliegende Erfindung bietet also den Vorteil, Steinbrecher auch zum Brechen solcher Materialien verwenden zu können, die bisher auf Steinbrechern überhaupt nicht verarbeitet werden konnten.The present invention thus offers the advantage of stone crusher also for breaking such To be able to use materials that were previously not processed at all on stone crushers could become.
