ABSTRACT:
The addition of calcium sulfate to an alkali metal aluminum phosphate slurry prior to drying provides an improved process which results in a cleaner reactor, easier drying and granulation, increased production rates, a decreased mill heat requirement and a product having an increased density which is less dusty allowing for easier handling, and substantially non-hygroscopic which avoids caking and blinding of classifier screens.
