Efficient fiber treatment with state-of-the-art products

    Well-founded knowledge and best products

    The process of refining fibers has a big effect on the energy balance of the production process. Refiner fillings optimally adapted to the fiber characteristics substantially increase the potential for energy and raw material savings. Voith is full line supplier in the application of fiber treatment and we support our customers with process know-how and excellent products like our Pluralis Line for refining or TheWall for dispersion.

    What makes our Pluralis so special?

      Our proven Pluralis design offers effective refining of the pulp in the stock preparation. Thanks to the special arrangement and shape of the bars, the fibers can be treated with low intensity resulting in the best product qualities.

      • Reduction in the number of refiners possible
      • High hydraulic capacity with low no load
      • Increased tear strength of the paper web
      • Less fines
      • Reduction of raw material costs by optimizing the potential of the fibers
      • Proven reduction of energy costs
      • Longer service life of the refiner fillings due to gentle refining (low-intensity refining)
      • Easy maintenance

      TheWall disperger filling

        Efficient fiber treatment through a unique design

        The innovative design of TheWall allows uniform distribution and feeding of the pulp. This is achieved by the rotor which is equipped with feeding vanes and the strategically arranged distribution teeth. The unique design with its partially closed tooth gaps allows operation of the filling with a gap width between 0.5 – 8.5 mm, with no untreated fibers passing the filling. TheWall also lowers energy consumption, while improving dispersion of dirt specks and stickies.

        Superior results are achieved by combining TheWall with the newly developed Voith disperger InfibraDisp and the Compact Dispersion System. In addition, the filling is available for all current Voith dispergers and selected dispergers from other manufacturers.
