Title (EN) METHOD AND APPARATUS FOR REFINING LIGNOCELLULOSE-CONTAINING MATERIAL
(FR) PROCEDE ET APPAREIL POUR RAFFINER UN MATERIAU CONTENANT DE LA LIGNOCELLULOSE
Abstract:
(EN) An apparatus for refining lignocellulose-containing material comprises a pressure-proof refiner housing (1, 40) with opposed refiner members (2, 3, 41, 42, 59, 60), which between themselves define a gap (8, 47). Liquid is supplied to the gap via radial passageways (12, 25, 26, 34, 50, 55, 56, 57) in a rotatable refiner member (2, 3, 42, 60), and the rotation of the refiner member brings about the desired pressure in the liquid, which pressure exceeds the pressure in the gap.
(FR) Un appareil pour raffiner un matériau contenant de la lignocellulose comporte un boîtier de raffinage étanche à la pression (1, 40) doté d'organes de raffinage opposés (2, 3, 41, 42, 59, 60) déterminant entre eux un intervalle (8, 47). Le liquide est amené à l'intervalle via des passages radiaux (12, 25, 26, 34, 50, 55, 56, 57) dans un organe de raffinage rotatif (2, 3, 42, 60) et la rotation de l'organe de raffinage provoque la pression désirée dans le liquide, pression dépassant la pression régnant dans l'intervalle.
