OBS

On utilise essentiellement deux grands types de raffineurs en continu pour préparer la pâte : les raffineurs à disques et les raffineurs coniques. On peut, en fonction des angles, séparer les raffineurs coniques en deux types, soit les raffineurs à petit angle (Jordan) et les raffineurs à grand angle (Claflin). [...] Dans les raffineurs coniques, des lames métalliques, orientées dans le sens de la longueur, sont fixées sur la partie tournante (rotor) en forme de cône et sur l'enveloppe (stator). Les fibres s'écoulent parallèlement aux lames. La position du rotor détermine l'espacement entre lames ainsi que le travail effectué sur les fibres.
