A spare part for disc refiners, in particular a stator and/or rotor used in a disc refiner for the preparation of paper pulp, where the stator and/or rotor each comprise a disc-shaped metallic element with a refining blade surface having alternating blades and grooves, where the rotor is designed to be driven and rotated around its own axis of rotation which passes through the centre of the disc-shaped element so that the rotor blades perform a rotary movement in front of the stator blades with a suitable air gap in between. The spare part is characterised in that the blade surfaces have a pre-set angle greater than 0° with respect to a plane perpendicular to the rotor axis of rotation, which enables the achievement of major advantages in terms of the quantity and quality of the refined product, and the potential to reduce the energy consumed.
