ABSTRACT A method and apparatus for manufacturing fibre pulp from ligno- cellulose-containing material are disclosed. Fibre pulp is manufactured in a refiner having opposed refining members which rotate relative to each other and are enclosed in a pressure-proof refiner housing. Steam is separated from the fibre pulp in the refiner housing at the counter-effect of centrifugal forces generated by radial wing members on a rotary refining member. The steam is led off separately from the refiner housing through a steam outlet which communicates with a space radially inside of the wing members. The fibre pulp is discharged separately through a discharge device while the desired pressure is maintained in the refiner housing.
