Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung eines Hartmetallansatzes aus Hartstoffanteilen, Bindemetallanteilen und wasserlöslichen Presshilfsmittelanteilen durch Trocknen eines die Bestandteile enthaltenden Nasschlammes mit reinem Wasser als Flüssigphase. Erfindungswesentlich dabei ist, dass zuerst die Hartstoff- und Bindemetallanteile mit Wasser unter Bildung eines Nassschlammes vermahlen werden und dass dem Nassschlamm nach dem Mahlen die Presshilfsmittelanteile in Form einer Emulsion zugemischt werden. Die Emulsion wird dabei mit Hilfe eines Emulgators unter Zugabe von Wasser hergestellt.
