Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung eines Hartmetallgranulates durch Nassmahlen und Sprühtrocknen in einem Sprühturm -1- unter Verwendung von reinem Wasser als Flüssigphase. Erfindungswesentlich dabei ist, dass der Sprühturm -1- so ausgelegt und betrieben wird, dass das Verhältnis der über den Nassschlamm zugeführten Wassermenge in Litern pro Stunde, bezogen auf das Turmvolumen in m3 im Bereich zwischen 0,5 und 1,8 liegt und dass maximal 0,17 kg Nassschlamm pro m3 Trocknungsgas zugeführt werden, wobei der Nassschlamm einen Feststoffgehalt im Bereich von 65 bis 85 Gew.% aufweist. Unter diesen Voraussetzungten kann die üblicherweise notwendige Zugabe eines wasserlöslichen, langkettigen Polyglykols zum Nassschlamm vor dem Versprühen, zur Verhinderung der Oxidation der Hartmetallgranulates, entfallen.
