Abstract

Proceso de granulacion de urea en un granulador que contiene nucleos de urea, al cual se agregan urea fundida y al menos un aditivo de granulacion, donde los nucleos de urea son transportados y la urea fundida se agrega perpendicularmente a la direccion de transporte de los nucleos de urea, donde el aditivo de granulacion se suministra al menos parcialmente a la ultima seccion del granulador.Urea granulation process in a granulator containing urea nuclei, to which molten urea and at least one granulation additive are added, where urea nuclei are transported and molten urea is added perpendicularly to the direction of nucleus transport urea, where the granulation additive is at least partially supplied to the last section of the granulator.
