KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bekanntermaßen ist der Stoffumlauf beim Holländer an der Außenwand des Troges langsamer als an der Scheidewand des Troges. Der an der Außenwand fließende Stoff ge-. 5 langt naturgemäß weniger oft zum Mahlwerk, wodurch eine ungleichmäßige Mahlung des Stoffes resultiert. Es ist daher notwendig, den um die Mittelwand fließenden Stoff gegen die Außwand des Troges zu drängen. NachIt is known that the material circulation in the Dutchman is on the outer wall of the trough slower than at the dividing wall of the trough. The fabric flowing on the outer wall. 5 naturally reaches the grinder less often, which results in uneven grinding of the substance results. It is therefore necessary to counter the fabric flowing around the central wall to push the outer wall of the trough. To
ίο vorliegender Erfindung wird dies dadurch erreicht, daß man dem Boden des Troges außer seinem bekannten Gefälle in der Richtung des Stofflaufes durchgehend ein Gefälle von der Mittelwand gegen die Außenwand des Troges gibt.ίο the present invention this is achieved by that you can reach the bottom of the trough except for its known slope in the direction of the head run continuously a gradient from the center wall against the outer wall of the Troges there.
Fig. ι stellt einen Längsschnitt eines solchen Holländers dar. Fig. 2 ist ein Schnitt nach Linie A-B und Fig. 3 ein Schnitt nach Linie C-D der Fig. 1.FIG. 1 shows a longitudinal section of such a Dutchman. FIG. 2 is a section along line AB and FIG. 3 is a section along line CD in FIG. 1.
Wie aus Fig. 2 und 3 ersichtlich, fällt der Boden des Troges von der Mittelwand d aus stets gegen die Trogwand e ab. Da außerdem der Holländerboden in bekannter Weise in seiner Längsrichtung von der Messerwalze um die Scheidewand d herum bis zur Rührwelle /2 abfällt, so wird ein Stauen des Mahl- ' gutes vor der Rührwelle verhütet und dieses ganz regelmäßig gemischt. Der seitliche Abfall des Trogbodens zieht sich bis ganz durch die beiden Trogbetten α und b. Bei einem solchen Holländer wird die Verschiedenheit in der Länge des inneren und äußeren Stoffweges ausgeglichen und der Stoff auf der ganzen Breite stets gleichmäßig und gleich oft dem Mahlwerk zugeführt, also gleichmäßig gemahlen.As can be seen from FIGS. 2 and 3, the bottom of the trough always drops from the central wall d against the trough wall e . In addition, since the Holländerboden falls in a known manner in its longitudinal direction from the knife roller around the partition d around to the agitator shaft / 2, the grist is prevented from jamming in front of the agitator shaft and this is mixed very regularly. The lateral drop of the trough bottom extends all the way through the two trough beds α and b. With such a Dutchman, the difference in the length of the inner and outer material path is evened out and the material is always fed to the grinder evenly and with the same number of times over the entire width, i.e. it is ground evenly.
