Abstract

UN GRANULADOR COMPRENDE UN ATOMIZADOR GIRATORIO (1) SOBRE EL QUE SE VIERTE EN UNA CORRIENTE EL MATERIAL FUNDIDO A GRANULAR. EL GIRO DEL ATOMIZADOR (1) PROVOCA QUE EL MATERIAL FUNDIDO SEA EYECTADO DE ALLI EN FORMA DE GLOBULOS. NO SE EMPLEAN CHORROS DE FLUIDO PARA DISOLVER EL MATERIAL FUNDIDO. LOS GLOBULOS PASAN A TRAVES DE UN RECINTO (6) Y SE CONGELAN PARCIALMENTE PARA FORMAR GRANULOS QUE SE RECOGEN EN UNA CUBA ANULAR (10). SE INYECTA UN GAS EN LA CUBA (10) PARA INDUCIR DENTRO DE LA MISMA UN MOVIMIENTO CIRCUNFERENCIAL DE LOS GRANOS DIRIGIDO HACIA AL MENOS UNA SALIDA DE DICHA CUBA.
