Description

Gebrauchsmuster A n a e lder : B-z-ichnun ! Mühlstein* und Mahlscheien für Mahlänse und ScheibeüQühl. Es sind bereits Mühlsteine und Mahlscheiben bekannt, die mit einer um die Achse sich spiralförmig windenden Luftfurche versehen sind.Utility model A nae lder: Bz-me well! Millstone * and grinding wheels for Mahlänse and DisküQühl. There are already millstones and grinding disks known that are provided with an air groove spiraling around the axis.

Die bisher verwendeten Mahlscheiben haben den Nachteil, dass sie eine zu geringe Scherkraft und Leistung haben. Infolge der ungleichmässigen Verteilung des Mahlgutes auf der Mahlbahn konnte auch keine gleichmässige Feinheit erzielt werden. The previously used grinding disks have the disadvantage that they have insufficient shear force and performance. As a result of the uneven distribution of the ground material on the grinding track could also not achieve a uniform fineness will.

Zweck dieses Schutzes ist die geschilderten Nachteile zu beseitigen. Diese bestehen darin, dass die Zahl der um die Achse sich spiralförmig windenden Furchen von O@er - und Untersteing unterschiedlich ist. Zweckmässig werden die zahnartig in die Mahl@ahn verlaufendenn Einschnitte mit Kanten senkrecht und schräg zur Schmeidrichtung versehen. The purpose of this protection is to eliminate the disadvantages described. These consist in the number of spirals around the axis Furrows of O @ er - and Untersteing is different. Appropriately, they become tooth-like Cuts running into the milling teeth with edges perpendicular and at an angle to the cutting direction Mistake.

Der Schutzanspruch ist in der Zeichnung beispielsweise dargestellt. The claim to protection is shown in the drawing, for example.

Abb. 1 zeigt zwei aufeinanderliegende Scheibe im Querschnitt, Abb. 2 eine umlaufende Mahlscheibe mit zwei Spiralen und Zufuhrungs-und Schneidzähnen zur eigentlichen Mahlbahn. l> Abb. 3 eine stillstehende Scheibe mit einer Spirale und Zuführungszähnen. Fach den Schutzanspruch werden doppelseitige Mahlscheiben h, i it mehreren dreieckigen Spiralfurchen a und b, in unterschiedlicher Zahl an Ober-un Unterstein versehen. Von den Furchen führen zahnartige Einschnitte zur Mahlbahn e.Fig. 1 shows two discs lying on top of one another in cross section, Fig. 2 shows a rotating grinding disc with two spirals and Feed and cutting teeth to the actual grinding track. l> Fig. 3 a stationary disc with a spiral and feed teeth. Subject to protection are double-sided grinding disks h, i with several triangular spiral furrows a and b, in different numbers of upper and lower stones. from the furrows lead to tooth-like incisions to the grinding path e.

Durch die Öffnung der stillstehenden Scheibe wird das Mahlgut mittels der Schläger d, in die Spiralfurchen a der umlaufenden, und b, der stillstehenden Scheibe eingeführt. Infolge der auf das Gut einwirkenden Schleuderkraft wird das Uahlut in die Zuführunszähe c, und von diesen zur Mahlbahn e geschleudert. Die senkrecht, zur Schneidrichtun- verlaufenden Spiralfurchen a uben ausserde, eine scheerende Wirun gegenüber der aten der Zähne c der stillstehenden Scheibe aus. Die Mahlbahn e kann mit Riffeln f zur weiteren Vermahlung versehen werden.Through the opening of the stationary disc, the ground material is fed into the spiral grooves a of the rotating, and b, inserted the stationary disk. As a result of the centrifugal force acting on the material the Uahlut in the Zuführunszäne c, and from these to Grinding track e thrown. The perpendicular to the cutting direction running spiral furrows also have a shear end Wirun opposite the ate of the teeth c of the stationary Washer off. The grinding track e can be provided with corrugations f for further grinding.
