Description
Verschleiß des Rades durch die zwischen Buchsen und Rad strömende Aufschlämmung vermieden wird. Da die Buchsen ein Stück in den ringförmigen Innenraum des Rades hineinragen, legt sich bei der Rotation eine Flüssigkeitsschicht an die Innenwand dieses Raumes. In dieser Flüssigkeitsschicht wird so viel aufgeschlämmtes Material auszentrifugiert, daß es die Bereiche um die in den ringförmigen Raum hineinragenden Teile der Buchsen ausfüllt. DieserWear of the wheel due to the between bushings and wheel flowing slurry is avoided. As the sockets are a piece in the annular Protrude into the interior of the wheel, a layer of liquid is deposited on the inner wall as it rotates this room. So much suspended material is centrifuged out in this liquid layer that it fills the areas around the parts of the bushings that protrude into the annular space. This

Das Rad ist für einen Zerstäubungstrockner bestimmt, in dem es an einer rasch rotierenden Welle montiert wird. Der ringförmige Raum des rotierenden Rades wird durch die öffnung 6 mit einer Aufschlämmung beschickt, die in zerstäubter Form durch die Öffnungen in der Außenwand 3 aus dem Rad in eine umgebende Trockenkammer geschleudertThe wheel is intended for a spray dryer in which it is attached to a rapidly rotating shaft is mounted. The annular space of the rotating wheel is charged through the opening 6 with a slurry, which is in atomized form thrown through the openings in the outer wall 3 from the wheel into a surrounding drying chamber

Obwohl die Buchsen aus verschleißfestem, gesintertem Material bestehen, werden sie nach und nach doch verschlissen, sind aber leicht auszuwechseln, da sie nur durch die Zentrifugalkraft festgehalten werden, die nicht wirksam ist, wenn das Rad stillsteht. Ihr Verschleiß ist einseitig, und deshalb läßt sich die Lebensdauer dadurch verlängern, daß sie nach undAlthough the bushings are made of wear-resistant, sintered Material, they are gradually worn out, but are easy to replace because they are only held in place by centrifugal force, which is ineffective when the wheel is stationary. Their wear is one-sided, and therefore the service life can be extended by gradually increasing them
