Abstract

"SEGMENTO DE REFINAçãO PARA A REFINAçãO DE MATERIAIS LIGNOCELULóSICO, E, REFINADOR POSSUINDO DISCOS OPOSTOS GIRANDO UM EM RELAçãO AO OUTRO". Uma placa refinadora para a face de um disco refinador, compreendendo uma pluralidade de segmentos refinadores dispostos lado a lado na face do disco para formar uma região refinadora essencialmente anular. Cada segmento refinador possui uma zona de refinação interna para receber o material a ser refinado e uma zona de refinação externa. A zona de refinação externa tem uma pluralidade de barras dispostas radialmente, definindo uma superfície de topo e uma pluralidade de canais dispostos radialmente, arranjados intermediariamente às barras, definindo uma superfície de base mais baixa. Pelo menos uma das superfícies de topo possui pelo menos uma ranhura se estendendo radialmente, definindo um par de lâminas e uma superfície de base intermediária no fundo da ranhura. A superfície de base intermediária está posicionada a uma altura intermediária à superfície de topo e à superfície de base mais baixa. A largura das ranhuras é mais estreita do que a largura dos canais.
