Abstract

The grinding discs of a refiner driven by an electric motor carry on the end faces facing each other material-grinding barriers or cutters which are arranged in groups in sectors and extend parallel to each other. To reduce the torsional excitation of the rotor shaft of the electric motor occurring during the operation of the refiner as far as possible, the sectors have irregular pitch or different sector angles along the circumference of the grinding discs.
