Abstract

LA INVENCION ESTA RELACIONADA CON UN METODO DE FABRICACION DE FERTILIZANTES DE NK, BASICAMENTE A PARTIR DE FERTILIZANTES DE NITRATO DE CALCIO Y NITRATO POTASICO, Y UNOS PRODUCTOS HOMOGENEOS DE FERTILIZANTE DE NK. SE FUNDE EL FERTILIZANTE DE NITRATO DE CALCIO JUNTO CON EL NITRATO POTASICO PARA FORMAR UN PRODUCTO FUNDIDO O UNA SUSPENSION QUE SE GRANULA PARA OBTENER EL FERTILIZANTE DE NK. EL FERTILIZANTE DE NITRATO CALCICO Y EL NITRATO POTASICO SE FUNDEN A 90 - 120 C Y POSTERIORMENTE SE CALIENTAN HASTA LA TEMPERATURA DE GRANULACION DESEADA, QUE ES DE 160 - 190 C PARA OBTENER UN PRODUCTO FLUIDO, Y DE 90 - 140 C PARA GRANULARLO. SE MEZCLAN LOS COMPONENTES EN UNAS PROPORCIONES QUE PERMITA OBTENER UN PRODUCTO FUNDIDO O UNA SUSPENSION QUE CONTENGA UN 40 - 14 % EN PESO DE NITRATO CALCICO, UN 55 - 85 % EN PESO DE NITRATO POTASICO, UN 0,5 - 6 % EN PESO DE AGUA, UN 0 4 % EN PESO DE NITRATO AMONICO Y UN 0 - 5 % EN PESO DE NITRATO MAGNESICO.
