摘要： A method for producing powder mixtures capable of inducing an even more intimate, microhomogeneous intermixing in a heterogeneous powder composed of at least two types of powders. The method is effective even for the mixing of an aggregable powder and a nonaggregable powder. According to the method, a heterogeneous powder composed of at least two type of powders that have been preliminarily mixed by stirring is introduced into an inlet while a rotating axle is turning and is axially transported within a cylinder by a screw. As the heterogeneous powder passes between rotating disks and fixed disks, it is subjected to a highly efficient mixing by compression and shear forces due to a sliding-shear action exerted between depressions and elevations installed on the opposing surfaces of the rotating disks and fixed disks. The mixture passes in sequence through multiple stages of the rotating and fixed disks. A powder mixture, which has been microhomogeneously interdispersed, is discharged from the outlet.
