Abstract

An apparatus for the defibration of sheets of cellulose, comprising: - a supporting case (12) having a cavity (14) and at least one radial slit (20) for feeding a sheet (S) to be defibrated; and - a rotor (16) having a longitudinal axis (24), rotatably mounted within said cavity (14) about an axis of rotation coinciding with said longitudinal axis (24) and comprising a plurality of toothed disks (28) fixed to one another so as to form a pack, in which said toothed disks (28) extend in a direction orthogonal to the longitudinal axis (24) of the rotor (16) and each disk is provided with teeth (30) set at a distance from one another in a circumferential direction, and in which the disks (28) are arranged in said pack so that the teeth (30) of the adjacent disks (28) are angularly staggered with respect to one another. Each of said teeth (30) is provided with an insert (42) made of a material with high resistance to wear, having a impact surface (44) inclined by an angle comprised between +1° and -5° with respect to a plane (54) orthogonal to the axis of rotation (24) and passing through a tip (52) located at the end of the impact surface (44). The tip (52) has a surface (58) comprised between an internal arched surface (60) with a radius of 0.1 mm and an external arched surface (62) with a radius of 0.3 mm.
