摘要：
The preparation of dry, stable granular material from water-soluble potassium and ammonium salts and a mixture thereof by subjecting a dispersion of crystals of the salt in an aqueous liquid to the action of a granulating device in the presence of calcium sulphate hemihydrate and a hydrophilic surface active agent to effect agglomeration of said crystals, and thereafter subjecting the agglomerated crystals to a drying operation.
