摘要： There is disclosed a process from producing granular sodium tripolyphosphate of predetermined particle size by means of calcining sodium orthophosphate dried from water solution and milled to a predetermined particle size. The tripolyphosphate is produced having approximately the same particle size distribution as the orthophosphate feed. Moisturizing the feed prior to calcining increases the assay of the product.
