Abstract

ELEMENTO DE LÂMINA PARA UM REFINADOR, E, REFINADOR PARA REFINAR MATERIAL FIBROSO. Um elemento de lâmina (4, 8) para um refinador (1) para refinar material fibroso e um refinador (1) para refinar material fibroso. O elemento de lâmina (4, 8) compreende uma primeira borda de extremidade (18) para ser direcionada para uma alimentação do material fibroso a ser refinado e uma segunda borda de extremidade (19) para ser direcionada para uma descarga do material fibroso refinado e uma superfície de refino (5, 9) compreendendo barras de lâmina (16) e ranhuras de lâmina (17) entre ela. A superfície de refino (5, 9) compreende pelo menos um bolso de equalização (23) que se estende ao longo da superfície de refino (5, 9) do elemento de lâmina (4, 8) e cruza várias das barras de lâmina (16) e várias das ranhuras da lâmina (17) para equalizar o fluxo do material fibroso ao longo da superfície de refino (5, 9).
