Abstract

Process for mechanical fibre removal from a lignocellulose material obtained by a preliminary impregnation treatment of chippings by a reagent which promotes softening of the lignin. Said process is characterized in that it consists in passing the material through an apparatus (20) of the crusher type with hammers and a cylindrical grid. This process ensures that the pulp obtained has a maximum of long fibres. The process also offers a lower energy consumption than in conventional disk-type refiners.
