Beschreibung
Zusammenfassung:	The invention relates to a method for producing a homogeneous mixture of hard material powders and binder metal powders without using grinding bodies, liquid grinding auxiliary agents and suspending media. According to the invention, the mixture components are mixed at close range while generating a high shearing collision velocity of the powder particles and are remotely mixed by rotating the mixing bed without resulting in a particle size reduction of the hard material powders.
