Abstract
Método de granulacion mejorado donde se usa un granulador que tiene un piso inferior de una seccion de granulacion cuyo fondo es una placa perforada, untubo de alimentacion de aire para cargar aire la fluidificacion hacia el piso inferior de lasecci on de granulacion,un tubo de alimentacion de aire ramificadosdesde dicho tubo de alimentacion de aire inferior para inyectar aire en la seccion de granulacion y boquillas inyectoras provistas en los centros de dichassalidas de aire parainyectar una materia prima fundida desde las boquillas inyectoras a nucleos aproximadamente esféricos en la seccion de granulacion,que hansido cargados después de hacer que el diámetro de partícula sea de 0,4 a 3 mm, para formar gránulos y elgranulador mejorado para formar gránulos inyectandouna materia prima fundida en la seccion de granulacion, a cuyos nucleos se ha dado un diámetro de partícula establecido con una direccion de la corriente deaire que pasa a través de los orificioshechos en la placa perf orada que tiene un ángulo de inclinacion con la direccion de la corriente de gránulos conrespecto al eje vertical. Las paredes divisorias son provistas en el piso inferior, con las paredes divisorias paralelas a las paredesdel granulador,de maneraqu e las paredes divisorias formen un pasaje en el cual los nucleos pueden ser movidos contínuamente desde la entrada a la salida del granulador y que lasparedes divisorias estén escalonadas, de manera que al menos una de lasparedes divisorias se extie nda desde una seccion lateral del granulador hacia laseccion lateral opuesta del mismo, y la otra pared divisoria se extienda desde la otra seccion lateral opuesta del granulador hasta la primera seccion lateraldel mismo.Tiene una configuracion alar gada especificada tal que la relacion L/M es de 2 o más pero de 40 o menos, en donde L es la longitud de la seccioninferior del granulador en la direccion de la corriente de gránulos y M es el ancho de la corriente degránulos.
