Abstract

"PAR DE ELEMENTOS DE REFINO COOPERANTES OPOSTOS". Um par de elementos de refino cooperantes opostos (1, 2) propostos para um refinador a discos para a desintegração e refino de material lignocelulósico em um intervalo de refinar entre dois discos de refinar em contra-rotação opostos. Os elementos de refino são propostos para serem dispostos em relação confrontante recíproca sobre discos de refinar opostos, e ambos os elementos de refino (1, 2) são formados com superfície de refinar com barras (3, 4) e ranhuras (5, 6). De maneira a prevenir que o vapor d'água gerado flua para trás no intervalo de refinar, um primeiro elemento de refino (1), que é proposto para um disco de refinar rotativo, é formado com uma primeira zona radialmente restrita (7) com barras elevadas (8) e uma segunda zona radialmente restrita (9) sem barras diretamente no exterior da primeira zona (7). Um segundo elemento de refino oposto (2) é formado com uma terceira zona radialmente restrita (10) sem barras, cuja terceira zona (10) é localizada diretamente em fronte da primeira e da segunda zona (7,9) sobre o primeiro elemento de refino (1).
