Description
Die Erfindung bezweckt die Beseitigung von Nachteilen bei bisher bekannten Schleudermühlenbauarten durch Verringerung des Verschleißes und des Kraftverbrauches bei gleichzeitiger Erhöhung einer fehlkornfreien Mahlfeinheit.The invention aims to eliminate disadvantages in previously known types of centrifugal mills by reducing wear and tear and power consumption while increasing a grain-free Fineness of grind.
Fig. ι zeigt einen Querschnitt durch Haube und Schlagwerkzeuge einer bisher bekanntgewordenen Bauart einer gehäuselosen Mühle, ίο Hierbei ist zwar der Verschleiß und Leistungsaufwand durch Fortfall äußerer Widerstände verringert, aber durch den offenen Querschnitt d gelangt noch eine erhebliche Menge Mahlgut unvermahlen zum Austrag, was einen schlechten Feinheitsgrad und einen erheblichen Fehlkornanfall zur Folge hat.Fig. Ι shows a cross-section through the hood and striking tools of a previously known type of housing-less mill, ίο Here, although the wear and tear and power expenditure is reduced by the omission of external resistances, but through the open cross-section d , a considerable amount of grist is still unmilled to the discharge, which is a results in a poor degree of fineness and a considerable amount of incorrect grain.
Fig. 2 zeigt eine bisher bekanntgewordene Bauart einer Mühle, deren Mahlquerschnitt infolge Versenkung der Schlagstiftringe in Nuten der Mahlscheiben voll ausgenutzt wird, welche zur Erhöhung des Feinheitsgrades. außerdem noch Sicht- und Nachzerkleinerungseinrichtungen vorsieht. Ein sich leicht zusetzendes Gehäuse ist hierbei erforderlich. Die Erhöhung der fehlkornfreien Mahlfeinheit steht bei dieser Konstruktion in keinem Verhältnis zum Leistungsaufwand, zum Verschleiß und zu ihrer Betriebsunsicherheit, weil sich das feinste, durch den Luftstrom in die Nuten α gesaugte Mahlgut festsetzen kann.Fig. 2 shows a previously known type of mill whose grinding cross-section is fully utilized as a result of the sinking of the striking pin rings in grooves of the grinding disks, which is used to increase the degree of fineness. also provides for sifting and re-shredding facilities. A housing that clogs easily is required here. With this construction, the increase in the fineness of grinding free of faulty grains bears no relation to the performance expenditure, the wear and tear and its operational uncertainty, because the finest ground material sucked into the grooves α by the air flow can become stuck.
Durch die Erfindung, dargestellt in Fig. 3, werden die Vorteile der bisher bekanntgewordenen Bauarten mit offenen Läufern nach Fig. ι und der Mühle mit yoll ausnutzbarem Mahlquerschnitt nach Fig. 2 dadurch vereinigt, daß die ,äußere Kante b der Nuten a, in denen die die Schlagstiftkreise zusammenhaltenden Ringe c umlaufen, abgeschrägt werden, so daß das Mahlgut sich nicht ansetzen kann, sondern infolge der Fliehkraft abgeschleudert wird.By the invention, shown in Fig. 3, the advantages of the hitherto known designs with open runners of Figure ι., And the mill combined with yoll ausnutzbarem Mahlquerschnitt of FIG. 2, characterized in that the outer edge b of the grooves a, in which the rings c that hold the striker circles together are beveled so that the grist cannot settle, but is thrown off as a result of the centrifugal force.
