<p>The invention relates to a method for defibring recycled fibre material in a drum pulper (1) provided with a substantially horizontal drum (2). Recycled fibre material and water are fed to the drum pulper (1) and the drum (2) of the drum pulper (1) is simultaneously rotated. When the drum (2) rotates, the recycled fibre material rises up in the rotating drum (2) and finally, due to gravitational force, falls back down. After falling and hitting to the bottom, the recycled fibre material is defibred, forming a fibre pulp mixture with water. A value of at least one parameter describing the defibration process or fibre pulp properties is measured on the basis of the drum pulper (1) or the resultant fibre pulp mixture, and this value is used for controlling the rotation speed of the drum (2) of the drum pulper (1). The invention also relates to a drum pulper (1) implementing the method of the invention.</p> |
