Beschreibung
Zusammenfassung:	FIELD: fertilizers. SUBSTANCE: peat, urea, and potassium salts are mixed in presence of ammonium phosphates and recycle product, and resulting mixture is then converted into granules, which are dried in heat carrier current. According to invention, ammonium phosphates are added in component mixing stage and process is carried out until homogeneous mass is formed; initial temperature of heat carrier is 450 to 750 C, and it is passed for 1.25-2.5 sec with average velocity 45-60 m/s. EFFECT: simplified process, significantly reduced expenses, reduced or practically prevented ammonia emission into atmosphere, and increased yield of desired product fraction. 1 dwg, 4 ex
