  Disk defibrator - Patent 4219166
When in the defibration process ample amounts of energy are used, as is common for instance in the manufacturing of thermomechanical pulp with a double disk defibrator, the quantity or steam produced is quite remarkable (in the order of 2 to 6 kg per second).
The material to be defibrated entering the feed means flows, owing to the funnel shape of the container, readily down along the margins to the feed screws, which further supply the material into the throat of the cutter disks.
For the steam generated during the defibration process there remains between the screws 3 a funnel-shaped space 7 of upwardly increasing cross-section, into which the steam may flow in the direction indicated by the arrow 5, and whence it flows onward through the container 9 to the vent aperture 6.

 Conceptual evaluation of three rotordynamical systems
A defibrator is a rotating machine that break raw material of cellulose into small fibres.
The fibre creation process is a complicated process to simulate, mainly because it is hard to model these type of three phase flow and its interaction with the rotor.
In this thesis three defibrator concepts are dynamically analysed without modelling the fibre creation process.

 The Hindu Business Line : Motor vibrator regulating the flow into a screw feeder
The company explained that the function of the motor vibrator is "to work in conjunction with the defibrator in feeding the wood-chips into the screw feeder at a predetermined rate."
The motor vibrator works in conjunction with the defibrator, and so it constitutes an integral part of the pulp-making machinery, reasoned Western and sought classification of the item under heading 8439.91 of the Customs Tariff Act (CTA), 1975.
The defibrator method is also known as Asplund-method, named after the Swedish engineer Arne Asplund who filed a patent on the method in 1931.
