Abstract

Die Erfindung betrifft eine Mischvorrichtung mit einer Mischtrommel (22) und einer an den Enden der Mischtrommel gelagerten Mischerwelle (23), wobei die Mischerwelle (23) sich radial nach außen erstreckende Schaufelarme (24) aufweist, an deren Enden bis nahe zur Mischtrommelwand reichende Schaufelblätter (25) angeordnet sind. Erfindungsgemäß weisen die Schaufelblätter (25) einen Verschleißschutz in Form einer Hartauftragsschweißung aus einem verschleißfesten Material auf.
