Abstract (en)
A wet particulate mass is converted to a crumbly state by mixing into the mass water absorbent synthetic polymer paricles, for instance cross linked sodium polyacrylate, which are either in the form of aggregates above 50 mu m formed from fines below 50 mu m or are in the form of a dispersion in water immiscible liquid of particles below 50 mu m.
