Abstract

UN SISTEMA EN EL QUE SE INTRODUCE AIRE EN DOS CAMARAS (38A,38B) FORMADAS EN UN DEPOSITO CERRADO (30) PARA RECIBIR LOS SOLIDOS SEPARADOS DESDE EL SEPARADOR (18). EL AIRE SE INTRODUCE EN DOS CAMARAS EN EL DEPOSITO CERRADO EN UNA DIRECCION OPUESTA A LA DEL FLUJO DE LOS SOLIDOS SEPARADOS A TRAVES DEL DEPOSITO. UNA DE LAS CAMARAS ESTA SITUADA DEBAJO DEL DIPLEX SEPARADOR (28) Y EN ALINEAMIENTO CON ESTE Y LA OTRA CAMARA RODEA A LA PRIMERA CAMARA. EL FLUJO DE AIRE A TRAVES DE CADA TRAYECTORIA PUEDE AJUSTARSE POR SEPARADO CUANDO ES NECESARIO.
