Abstract

SE DESCUBRE UN APARATO Y UN METODO PARA GRANULACION UNIFORME. EL METODO IMPLICA EL USO DE UN MATERIAL DE ALIMENTACION INICIAL QUE POSEE UN TAMAÑO DE PARTICULA DE -150 DE MALLA Y EL 90 % O MAS CON UN TAMAÑO DE PARTICULA DE 200. EL MATERIAL DE ALIMENTACION PUEDE CONCENTRARSE EN UN RECIPIENTE GRANULADOR QUE INCLUYE UNA PEQUEÑA CANTIDAD DE UN MATERIAL DE NUCLEACION CON UN TAMAÑO APROXIMADO DE -35 DE MALLA. SE INTRODUCE EL AGLUTINANTE EN EL RECIPIENTE GRANULADOR PARA DEPOSITAR EL MATERIAL DE ALIMENTACION PROGRESIVAMENTE EN CAPAS SOBRE EL MATERIAL DE NUCLEACION PARA FORMAR UN PRODUCTO FINAL QUE POSEE UNA DISTRIBUCION DE TAMAÑO DE -8 A +4 DE MALLA. EL METODO ESTA DISEÑADO PARA SER INTERRUMPIBLE Y ES PARTICULARMENTE UTIL PARA FORMAR GRANULOS QUE POSEEN UNA PLURALIDAD DE CAPAS DE MATERIALES DIFERENTES. EL METODO PRESENTA UNA CLARA MEJORIA SOBRE LOS METODOS ANTERIORES EN EL CAMPO, PUESTO QUE PUEDE FORMARSE UN GRANULO PARTICULARMENTE FINO EN UN PROCESO RELATIVAMENTE RAPIDO PARA OBTENER UN GRANULO QUEPOSEE UN ELEVADO VALOR COMERCIAL Y UNA ELEVADA RESISTENCIA A LA FRACTURA. ESTOS FACTORES SE PUEDEN CONSEGUIR ADEMAS DE UNA UTILIZACION DEL 100 % DEL PRODUCTO SIN RESIDUOS.
