Abstract
A method for preparing powder granules by a liquid condensation process comprising preparing a slurry by mixing powders, a binding agent and a binding agent soluble solvent, dropping the slurry to a binding agent insoluble solvent to fix the binding agent so that the binding agent can not be released to a surface of a droplet of the slurry, coagulating the droplet by solvent exchange between the soluble solvent inside the droplet and the insoluble solvent at the surface of the droplets, and separating the coagulated droplet from the insoluble solvent, drying it and completely removing a residual solvent.
