Abstract：Two kinds of stirring blades were used to prepare the spray granulation molybdenum powder. The effect of stirring rate and stirring blades on the homogeneity of the slurry and the microstructure, apparent density and fluidity of the spray granulation molybdenum powder were investigated in this paper. The results show that with the increasing of stirring rate, the homogeneity of slurry increases, the apparent density and fluidity are improved, the sphericity gradually goes better. The structure of stirring blades has an important influence on the spray-dried powders. In the experiment, the stirring blades combined helical blades with impeller blades is better suited for Mo slurry stirring process.
