The present invention relates to a method of manufacturing a rotor for a screening apparatus and a rotor structure for a screening apparatus. The rotor structure of the invention is particularly suitable in screening fibre suspensions of the pulp and paper industry. The apparatus according to the invention relates to a novel rotor construction, and especially to a novel means of fastening a turbulence element on the rotor surface. The rotor (10) of the present invention is provided with easily replaceable turbulence elements (30) so that at least a part of the rotor surface is provided with at least one area (12) having a surface configuration different from the remaining rotor surface (14), on which area (12) the turbulence element (30) is fastened.
La présente invention porte sur un procédé de fabrication d'un rotor pour un appareil de criblage et sur une structure de rotor pour un appareil de criblage. La structure de rotor selon l'invention est particulièrement appropriée pour le filtrage de suspensions fibreuses dans l'industrie du papier et de la pâte à papier. L'appareil selon l'invention porte sur une nouvelle construction de rotor, et, plus particulièrement, sur un nouveau moyen de fixation d'un élément de turbulence sur la surface de rotor. Le rotor (10) selon la présente invention comporte des éléments de turbulence facilement remplaçables (30) de sorte qu'au moins une partie de la surface du rotor comporte au moins une zone (12) ayant une configuration de surface différente de la surface de rotor restante (14), l'élément de turbulence (30) étant fixé sur ladite zone (12).
