Abstract

Se describe un aparato y un método para la granulacion uniforme. El método involucra el uso de uma materia prima inicial que tiene un tamaño de partícula de malla -150 y 90% o mayor de tamaño de partícula de malla 200. La materia prima se puede poner en contacto en una badeja granuladora que incluye una contidad menor de un material nucleante de aproximadamente malla -35. El material aglutinante se introduce dentro del granulador de bandeja para depositar en capas o estratificar progresivamente el material de la materia prima sobre el material nucleante para formar un producto final que tiene una distribucion de tamaño de mallo -8 a malla +4. El método se designa para ser interumpible y es particularmenteutil para formar gánulos que tienen una pluralidad de capas de materiales diferentes. EL método tiene una mejora marcada sobre los métodos de la técnica anterior puesto que se puede formar un gránulo particularmente fino en un proceso relativamente conveniente para dar por resultdo un gránulo que tiene un alto valor comercial y una alta resistencia a la ruptura. Estos factores se pueden alcazar además del uso del 100% del producto sin desechos.
