The invention is related to an apparatus for manufacturing fibre pulp from lignocellulose-containing material, comprising a housing (2) enclosing two refining disks (3, 4) having opposing refining elements (6, 7), which refining elements (6, 7) between themselves form at least one refining gap (8), in which refining gap (8) the lingocellulose-containing material is arranged to be disintegrated into fibre pulp, wherein at least one refining disk (4) is arranged on a rotary shaft (5) and is rotary in a direction of rotation (R) and having a rear side (11) away from the refining gap (8), so that a space (10) is created between the rear side (11) of the rotary refining disk (4) and the housing (2), which rear side (11) is provided with a centre (14), a circumference (17) and at least one wing member (12, 12a, 12b, 12c) arranged to prevent pulp from sticking on the rear side (11). According to the invention, the rotary refining disk (4) has at least one thought radial line (13) on its rear side (11) extending from the centre (14) to the circumference (17) and in that at least one wing member (12, 12a, 12b, 12c) is attached to the rear side (11) at an (alpha, alpha1, alpha2, alpha3) from the at least one thought radial line (13) and towards the direction of rotation (R). |
