Abstract

UNA CENTRIFUGA INCLUYE UN TRANSPORTADOR PARA DESPLAZAR EL MATERIAL AGLUTINADO A LO LARGO DE UN RECORRIDO DE FLUJO DEL MISMO EN DIRECCION A UNA ABERTURA DE DESCARGA DEL MATERIAL AGLUTINADO, E INCLUYE ADEMAS UN DEFLECTOR MONTADO EN EL TRANSPORTADOR Y DISPUESTO A LO LARGO DEL RECORRIDO DEL FLUJO DEL MATERIAL AGLUTINADO. EL DEFLECTOR SE DISPONE EN POSICION AGUAS ARRIBA, ORIENTADO PRACTICAMENTE EN DIRECCION OPUESTA A LA ABERTURA DE DESCARGA, CON PERFIL O SUPERFICIE CONCAVA. ESTE PERFIL O SUPERFICIE CONCAVA SIRVE PARA DIRIGIR UNA PARTE DEL MATERIAL AGLUTINADO QUE SE DIRIGE AGUAS ABAJO, SIGUIENDO EL RECORRIDO DEL FLUJO DEL MATERIAL, HASTA UN RECORRIDO DE RECIRCULACION O AGITACION DIRIGIDO PARCIALMENTE HACIA ATRAS, EN DIRECCION A UN DEPOSITO. LA RECIRCULACION O AGITACION DEL MATERIAL PARTICULADO FACILITA UN MEJOR LAVADO DEL MISMO Y MEJORA LA RETIRADA DE SOLUTOS O IMPUREZAS INDESEABLES DEL MATERIAL AGLUTINADO.
