[origin: EP0858880A2] An installation is for dewatering and fibrillation of lignocellulose material and has a screw. The screw body (2') is adjoined by a fibrillation body (9), which is cone-shaped with a diameter that decreases in the direction of the material flow. The screw body (2') and the fibrillation body (9) are joined firmly to each other. The fibrillation body (9) preferably features ribs (10') which may be at an angle in relation to the screw axis.
