Beschreibung
Zusammenfassung:	The invention discloses an adding method for a monoammonium phosphate anti-caking agent produced by a slurry method. The adding method is characterized in that in the process of production of monoammonium phosphate by using the slurry concentration method, an anti-caking crystallization additive is added before the monoammonium phosphate is crystallized, and the crystallization additive is added in phosphoric acid or a slurry neutralized by an ammonia. 本发明公开了种料浆法生成的磷酸铵防结块剂的加入方法，其特征在于：对于料浆浓缩法生产磷酸铵，在生产过程中磷酸铵结晶之前，加入防结块的媒晶剂，媒晶剂的加入位置为磷酸中或者氨中和后的料浆中。
