Abstract

La presente invenzione si riferisce ad un processo per la granulazione di un fertilizzante denominato nitrato ammonico, avente un tenore di azoto compreso fra il 25% ed il 34%, mediante formazione di impasti di NH4NO3, calcare e/o dolomia, solfato ammonico e/o fosfati ammonici e MgSO4, addizionato in uno qualsiasi dei suoi abiti cristallini e dei suoi differenti gradi d'idratazione, seguito da operazioni di granulazione o prilling e di raffreddamento.
