Abstract

La presente invención se refiere a un procedimiento para producir gránulos fertilizantes, que contienen urea y sulfato de amonio, por medio de la granulación de partículas en un lecho fluidizado, caracterizado porque se introducen las partículas de sulfato de amonio dentro de un lecho fluidizado por el urea a dichas partículas, en el lecho fluidizado, por el rociado de un líquido acuoso que contiene urea, con una concentración de la urea del 70 a 99.9 por ciento en peso.
