Abstract
Procedimiento para producir gránulos de urea, caracterizado por rociar una disolución acuosa de urea que tiene una concentración de urea de 70-99,9% en peso en núcleos fluidizados de urea en forma de gotas que tienen un diámetro medio de 20-120 a una temperatura a la que el agua se evapora de la disolución rociada en los núcleos y la urea cristaliza sobre los núcleos, para formar gránulos que tienen el tamaño deseado.
