Description
Federung von Federrollenmühlen Federrollenmühlen mit um senkrechte Welle umlaufender Mahlbahn und federnd dagegengepreßten und darauf abrollenden Walzen zeigen übereinstimmend das Merkmal, daß die Federkraft über einen meistens nach außerhalb des Mahlraumes reichenden Hebel, der auf die Achse der Mahlwalzen wirkt, ausgeübt wird. Bei den oft sehr großen Federdrücken, die solche Mühlen benötigen (bis zu 5o t je Walze), werden diese Hebelkonstruktionen sehr schwer und kostspielig; das um so mehr, als es sich bei solcher Bauart nicht nur um den Hebel selbst handelt, sondern um das ganze Schwingsystem, welches auf diese Weise auch einbezogen ist. Es handelt sich aber nicht nur darum, daß diese Teile schwer und kostspielig werden, sondern ein noch größerer Nachteil liegt darin, daß sie viel Platz beanspruchen" die Luftquerschnitte zum großen Teil abdecken u. dgl.Suspension of spring roller mills Spring roller mills with around vertical Shaft revolving grinding track and resiliently pressed against it and rolling on it show consistently the feature that the spring force mostly after outside of the grinding chamber reaching lever that acts on the axis of the grinding rollers, is exercised. With the often very large spring pressures that such mills need (up to 50 t per roller), these lever constructions are very heavy and expensive; all the more so as this type of construction is not just about the lever itself, but about the whole oscillation system, which is also included in this way. It is not just a matter of making these parts heavy and expensive, but an even bigger disadvantage is that they take up a lot of space " cover most of the air cross-sections and the like.
Nach der Erfindung werden alle diese Nachteile dadurch behoben, daß .die Anpreßvorrichtung der Mahlwalze, ein Druckbolzen oder eine Feder ohne Zwischenschaltung eines Hebels unmittelbar neben dem Scheitelpunkt der Walze an deren Lagerkörper von oben her angreift.According to the invention, all these disadvantages are eliminated in that .The pressing device of the grinding roller, a pressure pin or a spring without interconnection a lever immediately next to the apex of the roller on its bearing body attacks from above.
Durch diese Maßnahme findet .eine wesentliche Entlastung des ganzen Schwingsystems statt, die im Sinne der Erfindung noch dadurch gesteigert werden kann, daß die Druckwicklung der Anpreßvorrichtung möglichst senkrecht über der Stelle, .an welcher die H,auptmahlarbeit stattfindet, angeordnet wird.Through this measure there is a substantial relief of the whole Oscillating system instead, which are increased in the context of the invention can that the pressure winding of the pressure device as vertically as possible over the point . at which the main meal work takes place, is arranged.
Auf diese Weise bedarf es nur verhältnismäßig leichter und raumsparender Mittel, um' die Walze an ihrer Stelle zu halten.In this way, it only needs to be relatively lighter and more space-saving Means to keep the roller in place.
Die Abb. i bis q. zeigen zur Klarstellung des Standes der Technik Beispiele bisher gebräuchlicher Federungen bei solchen Mühlen; demgegenüber tritt in Abb.5 und der dazugehörenden Ansicht Abb.6 der Unterschied der Erfindung gegenüber dem Bekannten klar zutage.Figs. I to q. show to clarify the state of the art Examples of suspension systems in use up to now in such mills; on the other hand occurs in Fig.5 and the associated view Fig.6 the difference between the invention clearly evident to the known.
Der drehende Teil a der Walze ist in dem Lagerkörper b gelagert; hierauf drückt unmittelbar über der mit dem Pfeil P bezeichneten Hauptmahlstelle der Druckbolzen c, der bei diesem Beispiel durch die Blattfeder d angepreßt wird.The rotating part a of the roller is mounted in the bearing body b; on this presses the pressure bolt directly above the main grinding point indicated by the arrow P. c, which in this example is pressed by the leaf spring d.
Es wirkt somit nur eine aus der Drehbewegung der Mahlbahn entstehende geringe Zugkraft Z, die ohne weiteres von dem kleinen Querschnitte des in dem Schwingpunkt/ gelagerten Schwinghebels aufgenommen werden kann; weitere Beanspruchungen, insbesondere Biegebeanspruchungen, treten im Gegensatz zu den bisherigen Anordnungen nicht auf. Besonders vorteilhaft ist die Ausbildung, wenn in bekannter Weise die Schwingachse i parallel zur Mahlbahn bzw. Mahllinie 'a angeordnet ist, weil in diesem Fall besonders wenig Platz für eine starke Ausführung der Schwingachse besteht.There is therefore only one effect resulting from the rotary movement of the grinding path low tensile force Z, which is easily influenced by the small cross-section of the mounted rocker arm can be added; further stresses, in particular In contrast to the previous arrangements, bending stresses do not occur. The training is particularly advantageous if the oscillating axis is in a known manner i is arranged parallel to the grinding path or grinding line 'a, because in this case special there is little space for a strong design of the oscillating axis.
Der Druckkörper kann auch als Kolben einer hydraulischen oder pneumatischen Anpreßvorrichtungausgebildet sein, es kannaber auf ihn auch jedes Federsystem, wie es benutzt wurde, einwirken.The pressure body can also be used as a hydraulic or pneumatic piston Be formed pressing device, but it can also have any spring system, such as it was used to act.
