Die vorliegende Erfindung bezieht sich auf Schleudermühlen zum Zerkleinern bezw. Mahlen von Schlacken, Steinen oder anderen harten Stoffen, und besteht darin, dafs bei ihnen alle arbeitenden Geha'usetheile, um sie zu schonen, nachgiebig gelagert sind.The present invention relates to centrifugal mills for crushing BEZW. Grind of slag, stones, or other hard matter, and consists in that of them all working parts of the housing are flexibly stored in order to protect them.

In der Zeichnung ist die Erfindung zur Darstellung gebracht, und zwar zeigtIn the drawing the invention is shown, namely shows

Auf einem Schwellenpaar 1,1 ist das Gehäuse 2, welches die gesammte Vorrichtung umschliefst, angeordnet.The housing is on a pair of thresholds 1.1 2, which encloses the entire device, arranged.

Die Schlagwelle 3 ruht in beweglichen Lagern 4, deren Lagerschalen 6 die Bügel 8 umgeben.The impact shaft 3 rests in movable bearings 4, the bearing shells 6 of which support the bracket 8 surround.

Der Mahlkörper 12 besteht aus der Nabe 13, welche auf der Welle 3 aufgekeilt ist, und aus den Schlag- oder Brecharmen 14, die mit dem Radius einen spitzen Winkel bilden, und der Mahlkörper dreht sich in der Pfeilrichtung.The grinding media 12 consists of the hub 13, which is keyed on the shaft 3, and from the impact or breaker arms 14, which with make an acute angle with the radius, and the grinding media rotates in the direction of the arrow.

Das Mahlgut wird durch seitliche Oeffnungen 15 und 16 zugeführt, welche durch Schieber 17 oder dergl. verschlossen gehalten werden. Die Zuführung geschieht von Hand, wobei man das Mahlgut abwechselnd durch die eine oder durch die andere Oeffnung 15 einführen kann, je nachdem man beabsichtigt, das Gut von der einen oder anderen Seite der Bahn den Schlagarmen zuzuführen. Wird die Beschickung maschinell eingerichtet, so ist die Benutzung einer oberen Klappe 17 vorzuziehen, wobei man vermittelst einer umlegbaren Scheidewand 18 bestimmen kann, nach welcher Seite des Mahlkörpers das Mahlgut ablaufen soll.The ground material is fed through lateral openings 15 and 16, which through Slide 17 or the like. Are kept closed. The feeding is done by hand, whereby the grist is alternately passed through one or the other opening 15 can import the good from one side or the other, depending on what one intends to do Feed path to the hitting arms. If the loading is set up automatically, the It is preferable to use an upper flap 17, whereby one can be folded back by means of a flap Partition 18 can determine the side of the grinding body towards which the grist is running target.

Schwingend aufgehängte Platten 19, deren Obertheile einander zugeneigt sind, führen das Mahlgut in den Bereich der Schlagarme.Swinging suspended plates 19, whose Upper parts are inclined towards one another, lead the grist into the area of the striking arms.

Die Platten 19 haben die Form eines Kreisausschnittes und sind an ihrer Unterkante mit einem Flantsch 20 versehen. Sie tragen Einlagen 21 mit Leisten 22, die, wie die Fig. 3 zeigt, so verlaufen, dafs sie mit den von der Welle 3 gezogenen Radien und mit den Schlagarmen 14 spitze Winkel bilden.The plates 19 have the shape of a section of a circle and are provided with a flange 20 on their lower edge. They wear insoles 21 with strips 22 which, as shown in FIG Wave 3 drawn radii and form acute angles with the flapping arms 14.

Zwischen den von beiden Seiten hervorstehenden Leisten 22 kreisen die Schlagarme 14 und zerdrücken und zermahlen das Mahlgut, welches sie infolge ihrer eigenen Neigung und der Neigung der Leisten 22 gut erfassen können.The striking arms 14 circle between the strips 22 protruding from both sides and crush and grind the grist which they use as a result of their own inclination and the inclination of the bars 22 can grasp well.

Die mit Rippen besetzten geneigten Leitplatten 23 überdecken die'Gelenke der Platten 19.The inclined guide plates 23 covered with ribs cover the joints of the plates 19th

Die Platten 19 sind vermittelst Federn 28 und Bolzen 24 nachgiebig gelagert, so dafs unzerbrechliche Stücke keine Beschädigung der Mahlvorrichtung herbeiführen, sondern unzerkleinert die Mühle verlassen können.The plates 19 are resiliently mounted by means of springs 28 and bolts 24, so that Unbreakable pieces do not damage the grinding device, but rather do not crush them leave the mill.

Zu jeder Seite des Gehäuses 2 ist ein gebogener Arm 25 befestigt, in dessen Bohrung der Bolzen 24 gleitet. Vermittelst einer Hülse 26, die gegen den Bolzen 24 verstellt werden kann, wird der Ausschlag der Platten 19 eingestellt. Je weiter entfernt von dem Bolzen die Hülse 16 eingestellt wird, um so früherA curved arm 25 is attached to each side of the housing 2, in the bore of which the bolt 24 slides. By means of a sleeve 26, which can be adjusted against the bolt 24, the deflection of the plates 19 is adjusted. The further away from the bolt the sleeve 16 is adjusted, the earlier

it strikes when the spring 28 is compressed against the arm 25.

The grinding passage is closed on the lower side by an elbow (Fig. 4). This bow piece consists of a bow rail 30, on the transverse ribs 31 with acute-angled Edges 29 are attached. At the edges, the ground material that slides down within the channels formed by the ribs 22, processed again from the outer edges of the arms 14.

The bend is also resiliently mounted. The bolt 32 is at its upper end 33 articulated, which by means of a spring 35, which between the head 36 of the bolt 32 and a counter disk 37 is mounted on the support 34, the curved piece in the normal position holds on.

The flexible mounting of the lower end of the bend is illustrated in FIG. The axis 38 passed through the curved piece slides by means of the sleeves 40 in side slots 39 which are mounted in the housing wall. Is held the axle is suspended on both sides by a spring between the guide 42 and a collar 43 Rods 41.

If unbreakable pieces get on the bow piece, the spring 35 respectively. the springs of the rods 41 are compressed and the arms 14 gradually convey the pieces down out.

The grinding passage is covered by a guide 45 after the introduction openings.

At the grinding, the laterally enclosing the path of the beater arms 14 take after the above, resiliently suspended ribbed panels and the ribbed bow section part; the outermost edges of the flapping arms cooperate with the latter.

If the impact arms are attached as shown, the material is already being crushed before it has even reached the bend, because it is at an acute angle to the ribs 22 standing arms 14 capture the grist. But if the arms 14 are attached in such a way that if they show the same or a lesser inclination than the ribs 22, the material becomes longer grind between the outer ends and the ribs of the bow piece.

In both cases the speed of the grinding process is different from one another.

In any case, the invention consists in the fact that the plates 21 and the curved pieces after- ■ are generously stored.
