Abstract

Prosess og anordning for å produsere og avvanne cellulosemasse der defibrert cellulose er silt fior å ^eme planterester (shives), og nevnte masse deretter er firaksjonert i minst tre fraksjoner (10, 3, (3a), 12), der firaksjonene er behandlet hver fior seg og deretter brakt sammen helt eller delvis, og at firaksjoneringen fioretas i henhold til spesifikk overflate, fiortriimsvis med hydrosykloner, og at prosessen omfiatter prosesstriim (6, 7) som skiller ut fibrer med høy spesifikk overflate, fiortriimsvis tyimveggede fibrer, og at prosessen iimbefiatter prosesstegene (2) som skiller ut fibrer som har lavere spesifikk overflate, fiortriimsvis fibrer med tykkere fibervegg, og at en eller flere fiberfiraksjoner (3, 3a) er behandlet fior å bli delt, fibrillert og permanent kollapset, fiortriimsvis av en anordning som iimbefiatter en findelingsanordning (5, 5a) slik som en mølle, en rafifinør, en kulemølle eller liknende.
