Abstract
La présente invention concerne un procédé de production de produits fertilisants de soufre élémentaire-urée, comprenant la préparation durée fondue ; la préparation dune suspension de particules de soufre micronisé avec de leau ; le mélange de lurée fondue avec la suspension de particules de soufre micronisé avec de leau dans lequel les particules de soufre micronisé demeurent sensiblement sous létat solide micronisé ; et la pulvérisation du mélange durée fondue et d'une suspension de particules de soufre micronisé avec de leau dans un granulateur, leau dans le mélange étant purgée, ce qui résulte en la formation de granules de soufre-urée avec une distribution uniforme de lurée et des particules de soufre micronisé. Linvention concerne également une composition de fertilisant de soufre élémentaire-urée selon le procédé.
