Title (EN) METHOD AND APPARATUS FOR DETERMINING DEGREE OF BREAKING DOWN OF FIBER PARTICLES INTO FINES IN PULP
(FR) PROCÉDÉ ET APPAREIL POUR DÉTERMINER LE DEGRÉ DE DISSOCIATION DE PARTICULES DE FIBRE EN FINES DANS DE LA PÂTE
Abstract:
(EN) Determining a degree of breaking down of the fiber particles into fines in pulp is performed by transmitting (1000) optical radiation to the pulp (104); and determining (1002) the degree of breaking down of the fiber particles into fines in pulp (104) on the basis of a primary detection of optical powers of at least two different optical bands (106) interacted with the pulp (104), and at least one of the following secondary detections: polarization of optical radiation propagated through the pulp (104), a property of microwave radiation propagated through the pulp (104), a force caused by a movement between the pulp (104) and a material structure (400, 504, 506) in the pulp (104), and particles in at least one image of the pulp (104).
(FR) L'invention concerne la détermination d'un degré de dissociation de particules de fibre en fines dans de la pâte par transmission (1000) d'un rayonnement optique à la pâte (104). La détermination (1002) du degré de dissociation des particules de fibres en fines dans la pâte (104) est effectuée sur la base d'une détection primaire des puissances optiques d'au moins deux bandes optiques (106) différentes qui ont interagi avec la pâte (104), et d'au moins l'une des détections secondaires suivantes : polarisation du rayonnement optique propagé à travers la pâte (104), une propriété de rayonnement à hyperfréquences propagée à travers la pâte (104), une force provoquée par un mouvement entre la pâte (104) et une structure de matériau (400, 504, 506) dans la pâte (104), et des particules dans au moins une image de la pâte (104).
