Abstract (en)

[origin: WO2010071911A1] A device for comminuting a cellulose-containing feedstock in wood processing, in particular in the production of pulp, paper and wood panels, with the aid of grinding discs (1) rotating in relation to one another a small distance apart as well as a feed screw (8) for transporting the feedstock to the grinding discs (1). According to the invention, it is provided here that at least one of the grinding discs (1) has in the axial direction a layer structure with at least one outer layer (10) and at least one carrier layer (11), the at least one outer layer (10) having a higher modulus of elasticity, and a higher density, than the at least one carrier layer (11).
