Abstract

"PROCESSO PARA REFINO MECâNICO DE UMA COMPOSIçãO DE APARAS DE MADEIRA PARA PRODUZIR POLPA DE MADEIRA, E, APARELHO E PROCESSO PARA REFINO DE APARAS DE MADEIRA EM POLPA DE FIBRA DE MADEIRA" No refino mecânico de aparas de madeira para produzir polpa de madeira, a qualidade da polpa de madeira é melhorada empregando refino a baixa intensidade pelo menos em um estágio final de refino; o refino é realizado em um refinador de disco duplo ou um refinador de disco único a velocidades de rotação que são mais baixas do que aquelas empregadas convencionalmente, especificamente a menos do que 1200 RPM em um refinador de disco duplo e a pelo menos 1500 RPM em um refinador de disco único.
