Beschreibung
Zusammenfassung:	Blends of crystalline zeolites and sodium triphosphate are made. To this end, a zeolite suspension is spray-dried jointly with an aqueous sodium orthophosphate solution or suspension, in which the molar ratio of Na to P necessary to produce zeolite-free sodium triphosphate containing Na and P in a theoretical ratio of 1.66 is reduced by decrements of 0.01% per each 10% by weight proportion of zeolite in the blend. The zeolite suspension is sprayed separately from the orthophosphate solution or suspension at a separation necessary for the resulting zeolite particles to dry superficially and for the resulting phosphate particles to undergo at least partial condensation, and the superficially dry particles are contacted with the at least partially condensed particles.
