Abstract

To produce granular, free-flowing detergents containing sodium metasilicate, pentasodium triphosphate or zeolite NaA or a triphosphate/zeolite mixture, at least two of the components are first agglomerated and mixed as a granular preagglomertate with other components present in powder form and compacted by means of rolls, the pressure limit beyond which no further compaction is obtained not being significantly exceeded. The compactate is then size-reduced to the desired particle size.
