ABSTRACT:
Reactive metal granules, especially of magnesium and/or magnesium alloys, are produced directly from molten metal. The metal is fed under pressure to a granulation nozzle which forces the metal to acquire a circular motion of increasing velocity before it reaches the outlet of the nozzle and disintegrates successively into small fragments and droplets. These fragments and droplets are formed in an inactive gas atmosphere in an enclosed system and are thereafter solidified and cooled in a nonoxidizing cooling bath. An apparatus includes a granulation chamber made up of two parts which can be fitted to each other at various positions with an air tight locking system.
