<p>An apparatus for defibration of reclaimed paper or the like comprises a drum (1) arranged to be rotatable and having at its end an inlet for supplying the material (M) to be defibred and water and at its opposite end an outlet for defibred material. Guide elements (4) extending from the inner wall towards the rotational axis are arranged inside the drum for moving the material (M) along with the rotational movement (P) of the drum. The guide means are arranged to rotate substantially all the mass (M) to be defibred in the drum as a uniform accumulation in the lower part of the drum. The continuous relative movement of mass portions will rub the mass and generate forces breaking up fibre bonds.</p> |
