The rotor structure is particularly suitable in screening fiber suspensions of the pulp and paper industry. The apparatus relates to a novel rotor construction, and especially to a novel means of fastening a turbulence element on the rotor surface. The rotor is provided with easily replaceable turbulence elements so that at least a part of the rotor has at least one area—having a surface configuration different from the remaining rotor surface, on which area the turbulence element is fastened.	11-24-2011
