ABSTRACT:
A mixture of powdered materials is subjected in an enclosure to a dispersing movement such that the components of the mixture are caused to fall freely in a dispersed form. During the fall, the dispersed components are sprayed with a binder dissolved in a solvent. On completion of the spraying, the dispersing movement is continued and a vacuum is simultaneously drawn in the vessel until the binder is in a solid state. In this way, the solvent is recovered in part. The apparatus includes a closed rotary vessel, inside of which are a suction conduit and a spray conduit, extending into the vessel in alignment with the axis thereof; the conduits are prolonged in respective vertical portions capped with a suction head and a spray head.
