Abstract (en)
[origin: WO9321300A1] In the process described, the spray-dried material is sprayed either simultaneously or sequentially with a liquid, non-ionic surfactant and an aqueous solution on leaving the mixing unit, the granular material is free-flowing, without any need for a drying operation, and has a significantly increased bulk density.
