Description
Die Erfindung bezieht sich auf Mahlkörper, die zum Zerkleinern und Feinmahlen von Zement, Kalk, Erzen, Klinker, Steinen und Erden in Rohr- und Trommelmühlen aller Art, insbesondere auch in Verbundrohrmühlen, als Zerkleinerungswerkzeuge Verwendung finden und besteht darin, daß die Mahlkörper als dreiseitige Pyramide mit ebenen oder gewölbten Seitenflächen ausgebildet sind.The invention relates to grinding media which are used for crushing and fine grinding of cement, Lime, ores, clinker, stones and earth in tube and drum mills of all kinds, in particular also in composite tube mills, as comminuting tools are used and consists in that the grinding media as a three-sided pyramid with flat or curved Side surfaces are formed.
ίο Diese Mahlkörper haben gegenüber Stahlkugeln den Vorzug, daß sie große, gleichmäßige Auflageflächen besitzen und gegenüber anderen Mahlkörpern den Vorzug, daß die Möglichkeit des Kollems gegeben ist, wodurch die Auflageflächen ständig wechseln, so daß auch noch eine Spaltwirkung erzielt wird und der Mahlprozeß schneller vor sich geht. Bei den Pyramidenmahlkörpern ist sowohl die Punktberührung für die Spaltwirkung wie auch dieίο These grinding media have steel balls opposite the advantage that they have large, even contact surfaces and over others Grinding media have the advantage that the possibility of Kollems is given, whereby the Constantly change contact surfaces so that a splitting effect is also achieved and the Grinding process is faster. With the pyramid grinders there is both point contact for the splitting effect as well as the
ao sich stets gleichbleibende große' Flächenberührung für die Feinmahlung gegeben, so daß die aufgewandte Kraft in viel größerem Maße wie bisher in Zerkleinerungsarbeit umgesetzt wird.ao always constant large 'surface contact given for fine grinding, so that the force applied is converted into grinding work to a much greater extent than before will.
Pyramidenmahlkörper mit geraden Flächen sind auf der Zeichnung in Abb. 1, mit gewölbten Flächen in Abb. 2 dargestellt. Abb. 3, in der die einzelnen Flächen durch Schraffur unterschieden sind, stellt die Ansicht von oben dar. Die Punktberührung ist in Abb. 4 mit «, die Flächenberührung mit b bezeichnet. Abb. S stellt den Durchschnitt einer Mühle dar, .aus dem erkennbar ist, wie beim Drehen der Mühle die Pyramidenmahlkörper mit hochgenommen werden und wie eine ständige und schnelle Zerreibung des Mahlgutes zwischen · den einzelnen Mahlkörpern stattfindet.Pyramid grinders with straight surfaces are shown in the drawing in Fig. 1, with curved surfaces in Fig. 2. Fig. 3, in which the individual surfaces are differentiated by hatching, shows the view from above. The point contact is designated in Fig. 4 with, the surface contact with b . Fig. S shows the cross section of a mill, from which it can be seen how the pyramid grinders are lifted up when the mill is turned and how constant and rapid grinding of the material to be ground takes place between the individual grinders.
