Disk defibrator presenting a feed device for supplying the material which one desires to defibrate, such as wood chips, into the throat of the disk defibrator with the aid of a screw conveyor, the steam generated during the defibration process escaping through the feed device in countercurrent to the material flow and further passing to the atmosphere through an exit aperture on the feed device. The feed device includes two feed screws side by side with an intervening space into which the steam freely discharges. |
