Abstract
PARA UN PROCESO DE SUPRESION DE POLVO Y PARTICULAS FINAS DURANTE LA GRANULACION DE NITRATO DE AMONIO CON UN CONTENIDO DE NITROGENO DE 28-34,5% N DEBE ENCONTRARSE UNA SOLUCION CON LA QUE SE PUEDA OBTENER EN UN GRANULADOR UN NITRATO DE AMONIO CON UN ESPECTRO DE GROSOR DE GRANO DE 1 A 4 MM (VACIO). HAY QUE SUPRIMIR LA FORMACION DE GRANULOS FALLIDOS, EN ESPECIAL, LOS MUY PEQUEÑOS. ESTO SE CONSIGUE FORMANDO EN UNA PRIMERA ZONA DE GRANULACION, CON METODOS DE GRANULACION CONOCIDOS, EN GRANULADORES DE CARACOL, TAMBOR, ESFERODICOS Y/O SEPARADORES, EL GRANULADO CRUDO, FIJANDO ENTONCES AL GRANULADO CRUDO, EN UNA SEGUNDA ZONA DE GRANULACION A 100-125 (GRADOS) C, MEDIANTE ADICION EN CANTIDADES ADECUADAS DE UN SULFATO DE HIERRO BI- O TRIVALENTE CON AGUA DE CRISTALIZACION EL POLVO O LOS GRANULOS MAS FINOS OBTENIDOS EN LA PRIMERA ZONA DE GRANULACION.
