Abstract

A method for the defibration of lignocellulose-containing fibre material; such as wood chips, bagasse or the like, comprising preheating the fibre material with steam under pressure at a temperature of 140-190 DEG C in a preheater (3) and subsequent defibration under pressure in a defibrator (9). The fibre material is transferred from the preheater (3) to the defibrator (9) and simultaneously compressed and dewatered in a compressing worm (5) with a compression ratio of 1.5-3, preferably 2-3, for lowering the moisture ratio of the fibre material.
