Description

Zerkleinerungs- und Feinmahlvorrichtung. Zusatz zum Patent 426752. Die den Gegenstand des Patentes 426752 bildende Zerkleinerungs- und Mahlvorrichtung besteht aus zwei gegeneinanderlaufenden, flachhohlkegelartigen Gehäuseteilen, die auf ihrer Innnenseite mit radial verlaufenden Festhalte- und Führungsrippen versehen sind. Diese Rippen sind im Querschnitt kantig und nehmen in Tiefe und Breite nach dem Umfang hin allmählich ab; sie verhindern eine mit Zerkleinerung verbundene Kreisbewegung des Gutes auf den Gehäusewandungen, fördern dagegen das Gut radial nach dem Umfang hin, wobei die Gutteilchen sich lediglich durch gegenseitigen Druck selbst zerreiben.Crushing and fine grinding device. Addition to patent 426752. The comminuting and grinding device forming the subject of patent 426752 consists of two opposing, flat hollow cone-like housing parts which are provided on their inside with radially extending retaining and guide ribs. These ribs are angular in cross section and gradually decrease in depth and width towards the circumference; they prevent a circular movement of the material on the housing walls associated with comminution, but convey the material radially towards the circumference, with the material particles merely grinding themselves through mutual pressure.

Die vorliegende Erfindung ist eine weitere Ausgestaltung dieser Zerkleinerungs- und Mahlvorrichtung und besteht darin, daß auf den Innenflächen der Gehäuseteile ring- oder kreisförmige Rippen- aufgesetzt sind.The present invention is a further embodiment of this comminution and grinding device and consists in that on the inner surfaces of the housing parts ring or circular ribs are attached.

Diese ring- oder kreisförmigen Rippen erweitern die Wirkungsweise der Vorrichtung nach dem Hauptpatent nach zwei Seiten: Zunächst wirken sie als Gleitwiderstände gegenüber dem eingebrachten Mahlgut. Das-. selbe wird infolgedessen langsamer nach dem Umfang hingeführt und verbleibt längere Zeit in der Vorrichtung. - Die Folge ist verlängerte Mahldauer, was also insbesondere für härteres Gut in Frage kommt.These ring or circular ribs expand the functionality of the device according to the main patent on two sides: First, they act as sliding resistances compared to the introduced grist. That-. the same becomes slower as a result the scope and remains in the device for a long time. - The consequence is longer grinding time, which is particularly useful for harder goods.

Die kreisrunden Rippen bedeuten aber weiterhin einen verbesserten Schutz der Gehäuseteile. Sie wirken ähnlich wie Widerstandsrippen in einer Rinne, wo sie verhüten, daß das zugeführte Gut auf den Gleitflächen schleift, dagegen bewirken, aß die Zerkleinerung sich auf dem zugeführten Gut selbst abspielt, das sich vor diesen Gleitwiderständen ansammelt und dabei eine schiefe Arbeitsebene bildet.The circular ribs still mean an improved one Protection of the housing parts. They act like resistance ribs in a gutter, where they prevent the material fed in from dragging on the sliding surfaces, the comminution takes place on the supplied good itself, which is in front of itself accumulates these sliding resistances and thereby forms an inclined working plane.
