Abstract (en)

[origin: EP1038976A1] A melt granulation and comminution process, comprising gas heating of sprayed droplets within a cooling chamber having cooled walls, is new. A melt granulation and comminution process comprises spraying the melt into a cooling chamber using a fluid jet, the sprayed melt droplets being heated in the spray jet by post-combustion of hot gases within the cooling chamber and the cooling chamber walls being cooled to a surface temperature of below 400 (preferably below 300) degrees C.
