  • Rotor element and a rotor for a screening apparatus
    Patent number: 11135532
    Abstract: The present invention relates to a turbulence element for use with a rotor and a rotor featuring turbulence elements. The rotor is used in a screening apparatus of the pulp and paper industry. The turbulence element has a longitudinal centerline (CL); two longitudinal edges, a leading edge and a trailing edge; two opposite ends, a first end and a second end; and two surfaces, a top surface and a bottom surface arranged between the leading edge and the trailing edge. The top surface is divided into a leading surface having its origin at the leading edge, and a trailing surface having its origin at the trailing edge. The leading edge and the leading surface are provided with undulations (U).
    Type: Grant

  • Method of manufacturing a rotor for a screening apparatus, a rotor and a turbulence element for a rotor
    Patent number: 8714364
    Abstract: 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 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.
