KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
In Kugelmühlen werden die Panzerplatten bisher in der Weise befestigt, daß sie an den beiden Enden durch eine oder mehrere Schrauben mit versenkten Köpfen niedergehalten werden. Die Erfahrung lehrt, daß die Schrauben sehr bald zerreißen oder brechen, was vielfach dem schlechten Stoff der Schrauben zugeschoben wurde. Die Ursache dieser Brüche ist aber die, daß die Kugeln durchIn ball mills, the armor plates are so far attached in such a way that they are attached to the both ends held down by one or more countersunk-head screws will. Experience teaches that the screws tear or break very quickly, which was often attributed to the bad stuff of the screws. The cause of this But breaks is the fact that the balls break through
ίο das fortgesetzte Auffallen auf die Panzerplatten diese namentlich in den Faserschichten der dem Innern der Kugelmühle zugewendeten Fläche verlängern, wodurch gleichzeitig eine Ausbuckelung der Platte vor sich geht. Dadurch werden die Befestigungsschrauben sehr stark in Anspruch genommen und müssen schließlich dieser Inanspruchnahme unterliegen.ίο the continued attracting attention to the armor plates these in particular in the fiber layers facing the inside of the ball mill Extend the surface, which at the same time causes the plate to bulge. Through this the fastening screws are used very heavily and must ultimately be subject to this use.
Nach vorliegender Erfindung werden dieAccording to the present invention, the
Panzerplatten nur an einem Ende mittels Schrauben befestigt, während sie mit dem anderen Ende verschiebbar unter Leisten greifen, zu welchen das Kopfende der nächstfolgenden Panzerplatten benutzt werden kann. Fig. ι zeigt eine Reihe Panzerplatten im Schnitt und die Fig. 2 in oberer Ansicht.Armor plates attached only at one end by means of screws, while with the other end slidably grab under bars, to which the head end of the next following Armor plates can be used. Fig. Ι shows a number of armor plates in Section and Fig. 2 in top view.
Fig. 3 zeigt gleichfalls die obere Ansicht einer Reihe Panzerplatten, die jedoch nur mit je einer Schraube- befestigt werden.Fig. 3 also shows the top view of a number of armor plates, but only with one screw each.
Die Panzerplatten a, welche exzentrisch zur Drehmittellinie der Schleudertrommel gekrümmt sind, also schräg ansteigen, werden an ihrem erhöhten Ende d durch kräftige Schrauben b befestigt. Das andere Ende greift mit seiner ganzen Breite oder, wie dargestellt, mit einer abgesetzten Zunge c unter das. Kopfende d oder in einen Ausschnitt e des Flansches d, derart, daß bei einer Verlängerung der Platte, deren freies Ende sich tiefer unter das Kopfende der nächstfolgenden Platte einschiebt, keine ungünstig wirkende Spannung auftreten kann und die Schraubenbolzen nicht gefährdet sind.The armor plates a, which are curved eccentrically to the rotational center line of the centrifugal drum, that is to say rise at an angle, are fastened at their raised end d by powerful screws b. The other end engages with its entire width or, as shown, with a stepped tongue c under the head end d or in a cutout e of the flange d, in such a way that when the plate is extended, its free end extends deeper under the head end of the inserting the next plate, no unfavorable tension can occur and the screw bolts are not endangered.
Diese Einrichtung gewährt auch noch den Vorteil, daß nur die Hälfte der Schrauben erforderlich ist.This device also grants the advantage that only half of the screws is required.
