Abstract
Procédé de traitement de suspensions de fibres présentant une consistance élevée, caractérisé en ce que la suspension de fibres est amenée à s'écouler entre des surfaces où elle est soumise à des changements de direction opposés et répétés, ainsi qu'à des forces de cisaillement qui assurent la rupture des liaisons des fibres, afin de fluidiser la suspension de fibres, et en ce que de la matière ou de l'énergie est ajoutée et/ou enlevée de la suspension de fibres, pendant que cette dernière est à l'état fluidisé.
