Abstract
Inventia se refera la un procedeu pentru obtinerea unor granule mari de uree, conform caruia se efectueaza într-un bazin rotitor si înclinat a unei solutii de uree calda sau a unei topiturii de uree, împreuna cu particule nucleu solide, lichidul sau topitura calda solidificîndu-se pe particule nucleu, dupa care granulele formate se racesc si se siteaza, granulele mai mici decît marimea ceruta fiind recirculate ca particule nucleu, raportul între diametrul mediu al granulelor ce parasec bazinul si diametrul granulelor ce parasesc bazinul si diametrul granulelor nucleu fiind mentinut sub 3.
