PATENTSCHRIFTPATENT LETTERING
KLASSE 50: Müllerei.CLASS 50: Milling.
Patentirt im Deutschen Reiche vom 16. September 1897 ab.Patented in the German Empire on September 16, 1897.
Zum Zerkleinern von stückigen oder grobkörnigen Materialien, wie Kohlen u. s. w., auf bestimmte Kubikform verwendet man zweckmäfsig rotirende Walzen, wobei das zwischen dieser Walze und einer feststehenden Rückwand liegende Material durch an der rotirenden Walze befindliche Zacken, Vorsprünge u.s.w* mittelst Schneid- und Schlagwirkung zerkleinert wird. Hierbei müssen zweierlei Werkzeuge vorgesehen sein, einmal solche, welche in der Rotationsrichtung der Walze zerkleinern, und dann solche, welche die Zerkleinerung quer zu dieser Richtung vornehmen. Werden solche Walzen aus einzelnen Scheiben zusammengesetzt, so müssen dabei also zweierlei Scheiben oder Scheiben mit zweierlei Werkzeugen verwendet werden, welche beide arbeiten, und von denen die eine nicht nur als Zwischenscheibe zur Herstellung einer Lücke dient. Bei solchen Schneidewalzen werden sich die in radialer Richtung vorspringenden, zweckentsprechend flachen und scharfen Schneidewerkzeuge naturgemä'fs schneller abnutzen als die tiefer liegenden und dabei breiteren, in Richtung der Walzenachse angeordneten Querschneiderippen. For crushing lumpy or coarse-grained materials such as coal and so on In a certain cubic form, rotating rollers are expediently used, with that between This roller and a fixed back wall lying material through on the rotating Prongs located on the roller, protrusions, etc. * by means of cutting and striking effects is crushed. Two types of tools must be provided here, one of them, which crush in the direction of rotation of the roller, and then those which do the crushing across this direction. If such rollers are composed of individual disks, two things must be done Discs or discs are used with two types of tools, which both work, and one of which is not only used as an intermediate disk to create a gap. at such cutting rollers are those protruding in the radial direction, appropriately Flat and sharp cutting tools naturally wear out faster than those deeper and wider cross-cutting ribs arranged in the direction of the roll axis.
Zweck der vorliegenden Construction ist der, die Zerkleinerungswalze derart zu gestalten, dafs beide Schneidewerkzeuge ganz unabhängig von einander und beliebig, je nach Abnutzung, ansgewechselt werden können, und dafs sowohl der Zeit- als Arbeitsaufwand hierfür der denkbar geringste ist.The purpose of the present construction is to design the shredding roller in such a way that both cutting tools completely independent of each other and arbitrarily, depending on wear and tear, can be changed, and that both the time and effort required for this is the least conceivable.
Die Arbeitsweise ist derart, dafs das zu zerkleinernde Material in den Raum R (Fig. 3 a) zwischen der Schneidewalze SW und der feststehenden Rückwand A eingebracht und durch die Längsschneider m, wie durch die Querschneider ν in den entsprechenden Richtungen zerkleinert wird.The mode of operation is such that the material to be shredded is introduced into space R (FIG. 3 a) between the cutting roller SW and the fixed rear wall A and is shredded in the corresponding directions by the longitudinal cutter m, as by the cross cutter ν.
Die Walzenscheiben W bilden, mit ihren Stirnflächen unmittelbar zusammengelegt, eine ohne Zwischenraum durchlaufende Walze, wobei die Knaggen k jeder Scheibe sich in entsprechende Lücken / der folgenden Scheibe legen, so dafs beim Rotiren eine feste Kuppelung vorhanden ist. Die Vorsprünge ν bilden die durchlaufenden Querschneiderippen. Die radial vorspringenden Längsschneidewerkzeugem sind zu dem aus einem Stück hergestellten Messerring M vereinigt, der in {lie seiner Form entsprechend hergestellte Vertiefung α der Walzenscheibe eingelegt wird. Dabei wird der Ring M durch den Nabenring η der Scheibe W centrirt und die Schneidewerkzeuge m legen sich mit ihren entsprechend verstärkten Wurzelenden in die Aussparungen w der Walzenscheiben. Die nächste Walzenscheibe legt sich mit ihrer ebenen Stirnseite χ gegen die freie Stirnseite y des Messerringes, so denselben gegen achsiale Verschiebung sichernd.The roller disks W , with their end faces placed directly together, form a roller that passes through without a gap, the lugs k of each disk being placed in corresponding gaps / of the following disk, so that a firm coupling is present when rotating. The projections ν form the continuous cross-cutting ribs. The radially projecting longitudinal cutting tools are combined to form the knife ring M made from one piece, which is inserted into the recess α of the roller disk, which is made in accordance with its shape. The ring M is centered by the hub ring η of the disk W and the cutting tools m are positioned with their correspondingly reinforced root ends in the recesses w of the roller disks. The next roller disk lies with its flat end face χ against the free end face y of the knife ring, thus securing it against axial displacement.
Die Herstellung bezw. Wiederzusammensetzung einer vollständigen Schneidewalze geschieht also durch einfaches Einlegen des Messerringes M in die Walzenscheibe W und unmittelbares Aneinanderlegen der einzelnen Walzenscheiben W ohne Anwendung von Schrauben u. s. w. Die Zweitheilung zwischen Längs- und Querschneider gestattet, die einzelnen Theile in. verschiedenen Härtegraden entsprechend der stattfindenden Beanspruchung herzustellen.The production respectively. Reassembly of full cutting roller so happens through simple insertion of the knife ring M in the rolling wheel W and immediately abutting the individual rolling disks W without the use of screws, etc. The bipartition between longitudinal and transverse cutter permits to produce the individual parts in. Different degrees of hardness corresponding to the occurring stress.
