Description
Die Erfindung betrifft eine Zerkleinerungsvorrichtung mit einer, iumlaufenden Brechwalze mit rauher Mantelfläche und einem gleichfalls rauhen Widerlager. Sie verfolgt,das Ziel, .eine gleichmäßige und vollständige Zerkleinerung besonders von hartem Mahlgut in wirtschaftlicher Weise, also mit verhältnismäßig einfachen und daher billigen Vorrichtungen durchzuführen, die wenig zu Verschleiß neigende Teile haben. Dies wird gemäß der Erfindung dadurch erreicht, daß die Brechwalze langsam, d. h. mit einer Umfangsgeschwindigkeit- von etwa i m/sec und weniger umläuft und langsam hin und her bewegt wird, während das Widerlager gegen die Walze und von ihr weg schnelle Schwingungen ausführt.The invention relates to a comminuting device with a rotating Crushing roller with a rough outer surface and an equally rough abutment. she pursues the goal of. an even and complete comminution, especially of hard grist in an economical way, so with relatively simple and therefore cheap devices to carry out the little to wear-prone parts to have. This is achieved according to the invention in that the crushing roller slowly, d. H. with a peripheral speed of about 1 m / sec and less revolves and is slowly moved back and forth while the abutment is against the roller and off your way carries out rapid vibrations.
Die Zeichnung stellt schematisch Ausführungsbeispiele,der Erfindung dar und zeigt in den Abb. i, 2 und 3 je eine Zerkleinerungsvorrichtung im Schnitt.The drawing shows schematically exemplary embodiments of the invention and shows in Figs. 1, 2 and 3 each a shredding device in section.
Die mit. einer rauhen Mantelfläche ausgestattete Brechwalze i (Abb. i) läuft im Sinne des Pfeiles langsam um. Ihr gegenüber ist ein zwischen den beiden Teilen sichelförmigen Arbeitsraum 2 bilden-.des Widerlager 3 vorgesehen, dessen wirksame Fläche gleichfalls rauh ausgebildet ist. In nicht dargestellter Weise wird die langsam umlaufende Brechwalze auch hin und her bewegt, was entweder in Richtung auf das Gut, also auch auf das Widerlager hin, und von diesem weg erfolgen kann, aber auch in axialer Richtung sowie gemeinsam in beiden Richtungen. In gleichfalls nicht dargestellter Weise kann ferner dafür gesorgt sein, daß das Widerlager 3 in schnelle Schwingungen versetzt wird.With. crusher roller i equipped with a rough outer surface (Fig. i) runs slowly around in the direction of the arrow. Opposite her is one between the two Share sickle-shaped work space 2 form-.des abutment 3 provided, its effective surface is also rough. In a manner not shown the slowly rotating crushing roller also moves back and forth, which is either in the direction can take place on the property, i.e. also on the abutment, and away from it, but also in the axial direction and together in both directions. In the same way In a manner not shown, it can also be ensured that the abutment 3 in rapid vibrations are caused.
Die Aufrauhung der Walze i und der Widerlagerfläche 3 kann durch darauf vorgesehene Vorsprünge erfolgen. Die Teile können auch höhl ausgebildet sein zur Hindurchleitung von Heiz- oder Kühlgasen zwecks mittelbarer Kühlung oder Trocknung des Gutes.The roughening of the roller i and the abutment surface 3 can by on it provided projections take place. The parts can also be designed to be hollow Passing through heating or cooling gases for the purpose of indirect cooling or drying of the good.
Abb. 2 stellt die Anordnung der Zerkleinerungsteile in einem Gehäuse dar. Öffnungen 4 sind hierbei im Widerlager 5 vorgesehen, um das fertig behandelte Gut hindurchfallen zu lassen. In das Gehäuse 6 könnendurch die Zuleitung 7 Heiz- oder Kühlgase zur unmittelbaren Einwirkung auf das Gut eingeführt werden, welches durch ein am Grunde des Gehäuses 6 vorgesehenes Schleuderwerk 8 zur besseren Erfassung nochmals aufgewirbelt wird.Fig. 2 shows the arrangement of the comminution parts in a housing represent. Openings 4 are here provided in the abutment 5 to the finished treated To let fall through well. In the housing 6 through the feed line 7 heating or cooling gases are introduced to act directly on the good, which by a centrifugal mechanism 8 provided at the bottom of the housing 6 for better detection is whirled up again.
Die große, sehr langsam umlaufende Wälze i zieht das Gut in den sichelförmigen Arbeitsraum 2 hinein, wo es teils durch Druck und teils :durch Reibung in sich und andenrauhenBegrenzungsflächeni und 3 zermalmt wird.The large, very slowly rotating roller i pulls the goods into the sickle-shaped one Workspace 2 into it, where it is partly due to pressure and partly: due to friction in itself and the rough boundary surfaces i and 3 is crushed.
Abb. 3 zeigt, wie stückiges und feineres Gut 9 mit dem hin und her gehenden becherförmig ausgesparten Druckkolben, io zwangsläufig an die sehr langsam umlaufende Walze i i gedrückt wird.Fig. 3 shows how lumpy and finer goods 9 with the back and forth going cup-shaped recessed plunger, io inevitably to the very slowly rotating roller i i is pressed.
Für die praktische Ausführung kommen Durchmesser der Walzen von 2 bis 4 m und Drehzahlen von drei bis fünf Umläufen je Minute in Frage.For the practical implementation, the diameter of the rollers is 2 up to 4 m and speeds of three to five revolutions per minute are possible.
