Beschreibung
Zusammenfassung:	FIELD: mineral fertilizers. ^ SUBSTANCE: process is accomplished in drum granulator-drier by spraying of suspension of lime-ammonium nitrate having moisture content 15-25% with air supplied under pressure, removing moisture in flue gas flow followed by cooling and classification of product. Invention is characterized by that, before spraying, inorganic polymers are added to suspension in amount large enough to increase viscosity of suspension by a factor of 2-5, said inorganic polymers being selected from suspensions of bentonite clays, attapulgite clays, liquid glass solution, Aerosil powder, and amorphous silica. ^ EFFECT: reduced dust formation and increased output of commercial product fraction. ^ 2 cl, 1 tbl
