Abstract

Oppfinnelsen vedrører en metode for fremstilling av gjødningsmiddelgranulater inneholdende urea og ammoniumsulfat og som har en ammoniumsulfat konsentrasjon på < 60 vekt %. I følge oppfinnelsen blir a) en smeltesuspensjon omfattende ammoniumsulfat med en gjennomsnittlig partikkelstørrelse i området fra 30 til 300 /xm og urea dannet ved en temperatur fra 120 til 155°C, b) deretter blir den i trinn a) dannede smeltesuspensjon ved hjelp av minst en dyse fra undersiden dyseforstøvet på finpartiklede ammoniumsulfat partikler hvorved det fluidiserte lag brytes opp (spres) ved hjelp av en oppbrusningsluftstrøm i området for inndysningsstedet og deretter c) fraskilles og eventuelt opparbeides det i det fluidiserte lag dannede gjødningsmiddelgranulat. På denne måte kan det fremstilles homogene urea- ammoniumsulfat granulater med et ammoniumsulfat innhold på 30 til 60 vekt % uten problemer, i det komstørrelsen av granulatet kan innstilles målrettet og støvutslippene ved granuleringen kan reduseres til et minimum.
