Abstract

SE PRESENTA UN PROCESO Y UN SISTEMA PARA CLASIFICAR ASTILLAS DE MADERA SEGUN SU TAMAÑO PARA SUMINISTRAR UN FLUJO DE ASTILLAS DE MADERA QUE SEAN ACEPTABLES PARA SER ALIMENTADAS A UN PROCESADOR DE UN SISTEMA DE PREPARACION DE PULPA. SE SUMINISTRA UNA ESTACION TAMIZADORA DEL FLUJO QUE DIVIDE UN FLUJO DE ENTRADA NO ACEPTABLE (FO) EN DOS FLUJOS FRACCIONALES (F1, F2) NINGUNO DE LOS CUALES ES ACEPTABLE PARA SER ALIMENTADO HASTA EL PROCESADOR. UNO DE LOS FLUJOS DE SALIDA DEL TAMIZ SE CONCENTRA DENTRO DE LAS ASTILLAS CON UN TAMAÑO MAYOR Y UN GROSOR MAYOR EN RELACION CON EL FLUJO DE ENTRADA. EL OTRO FLUJO DE SALIDA SE CONCENTRA DENTRO DE LAS ASTILLAS POR DEBAJO DEL TAMAÑO Y LAS PARTICULAS EN BASE AL FLUJO DE ENTRADA. LOS FLUJOS DE SALIDA DEL TAMIZ SE ALIMENTAN ENTONCES HASTA UN SEGUNDO Y TERCER TAMIZ (14, 16) QUE SEPARAN LOS TAMAÑOS POR ENCIMA Y POR DEBAJO A PARTIR DE LOS RESPECTIVOS FLUJOS DE ENTRAS PARA SUMINISTRAR FLUJOS ACEPTABLES PARA EL PROCESADOR.
