Abstract: 569,236. Granulating metal and alloys. LUX, E. Nov. 6, 1943, Nos. 18455/43 and 21525/44. [Class 82 (ii)] In a process for granulating metals and alloys, the molten metal in the form of fine jets meets a quickly-moving continuous wet surface at such an angle that the dispersed metal particles are thrown into water by the shortest possible path. The moving surface may be that of a non-metallic roller 5, the lower part of which is immersed in water in a tank 7. Above the roller is situated a container 1 for the molten metal, having apertures 3 for producing fine jets of the molten metal or alloy, which meet the roller near its edge, almost like vertical tangents. The grade of the produced granules is determined by controlling the temperature of the molten jet as it meets the moving wet surface, the finest grade being produced by cooling the jet so that the metal or alloy is near its solidification point as it meets the moving surface.
