Beschreibung
Zusammenfassung:	FIELD: mineral fertilizers. ^ SUBSTANCE: invention relates to granulated mineral fertilizers containing ammonium phosphates modified by surfactants and powdering substances, which do not lose their physicochemical properties during transportation and storage. Manufacture process comprises granulation of ammonium phosphate pulp, drying of granules, sorting and selection of commercial fraction, cooling and addition of modifying supplements. The latter are added in the cooling stage into zone with bed temperature by 5-10°C exceeding temperature of cooled product. Conditioning additives utilized can be either only liquid or the same mixed with dry powdering substances. ^ EFFECT: improved quality of surface coverage and simplified process. ^ 2 cl, 3 ex
