Your paper quality starts with screening efficiency

    screening rotor by Voith
    Screening requirements have changed tremendously over the last years. Inferior raw material properties for pulp and paper as well as increasing papermaking manufacturing costs, like energy, have led to higher demands for energy-efficient products and to further process optimizations. Therefore, all manufacturers had to increase their effectiveness in order to compete and be sustainable in the globalized pulp and paper industry environment.

    Slot screen baskets

      Voith C-bar
      Proven C-bar technology

      In recent benchmark studies, C-bar proved to be the most reliable slot screen basket in terms of high efficiency and throughput rate with the lowest specific energy consumption and minimum fiber loss. This success is based on the unique C-bar profile, paired with overlapping bar design arrangement.
      The C-bar screening cylinder is applicable for all kinds of stock in the most varied stock preparation and approach flow processes. One major advantage: The C-bar basket can also be used for high stock consistencies and trash loads.

      C-bar HerculeXX

      C-bar HerculeXX – even stronger than HerculeX

      With innovative end ring-cylinder connection
      C-bar HerculeXX from Voith
      In some applications, especially in pulp production, the stresses are very high. Here, there is a need for even more stable screen baskets, especially in the area where the screen cylinder connects to the end ring.
      The C-bar HerculeXX has been developed precisely for these requirements. This screen basket combines the hybrid technology of the HerculeX with an innovative screw connection of the end rings to the screen cylinder – all the while retaining the high open screen surfaces.
      In addition, the unique screw connection of the end ring offers the possibility to reuse it when replacing the screen cylinder, which contributes to a sustainable material usage reduction.

      C-bar HerculeX

      Strong. Solid. Stable.

      To withstand the enormous flow and pressure conditions in screening applications, Voith has developed the strongest screen basket on the market – C-bar HerculeX.

      Thanks to the new and innovative hybrid technology, the screen basket copes with maximum loads. In combination with C-bar technology, which has been used successfully for over 25 years, it is the ideal screen basket for applications with demanding requirements.

      C-bar HerculeX by Voith

      Maximum throughput is achieved by means of the clamping technology for the large open screening surfaces and the C-bar bar geometries. The special manufacturing process and wear-resistant material of the screen basket also reduce investment cost. The new screen basket can be customized to meet individual screening requirements and production conditions. Bar width and angle, slot width and chrome layer thickness can all be selected individually.


      In combination with the proven Voith EclipseRotor, an optimal and reliable screening process will be achieved. The C-bar HerculeX screen basket can be used in all Voith and non-Voith sorters.

      Your benefits with C-bar HerculeX

      • Maximum stability in applications with high stock consistencies and rotor speeds such as broke screening and pre-screening
      • Efficient screening due to individual adjustment of slot widths and geometries combined with proven C-bar technology
      • Low investment costs compared to welded or bonded screen baskets
      • Cost savings for screen maintenance
      • Maximum throughput due to large open screen area
      • Long service life thanks to wear-resistant material

      Hole screen baskets

        The Voith NDura hole screen basket offers precise and reliable technology for centrifugal pressure screens. They are ideal for use in stock preparation, as well as broke, pulp and approach flow screening.

        The optimization of the pitch design leads to an achievement of the highest open screen areas and, as a result, to a high throughput. The high separation rates of dirt and impurities contribute to quality improvements in the end products. Constant advances in our manufacturing techniques yield the highest precision in different hole designs and roundness of the screen basket. Each screen basket is equipped with the Voith hard chrome-plating technology and possesses a high wear protection.

        The highly sophisticated products are suitable for Voith screens and for all current machines and associated rotor combinations of other manufacturers.

        Screening rotors

          MultiFoil rotor by Voith

          Higher demands in raw material screening require increased screening efficiency and pose distinct challenges for facility operators. Voith screening rotors are the ideal answer, combining maximum screening quality and throughput with optimal energy use in each area of application.

          EclipseR Rotor

          Unique geometry for maximum energy savings

          In the sorting process, high levels of impurities cause rapid wear and a high maintenance effort for rotors. Voith's EclipseR rotor not only withstands high reject levels, but also saves up to 35% of your energy requirements. These are convincing arguments, as the EclipseR rotor is already successfully used in several production lines.

          Because of its novel foil geometry and configuration, the EclipseR rotor facilitates optimal screening efficiency, especially in screening applications that are heavily loaded with impurities. The flat but effective foil geometry of the EclipseR rotor generates a strong suction impulse and keeps the screen free for the highest throughput, even with high pulp consistencies of up to 5%. The EclipseR rotor was developed specifically for screening applications that are energy-intensive and heavily loaded with impurities. It is suitable for use in stock preparation, broke and pulp screening by Voith screening systems and all common machines from other manufacturers.

          MultiFoil Rotors

          Innovative blade geometry increases screening efficiency

          MultiFoil rotors are the ideal combination of the highest screening quality and throughput rates. Innovative blade geometry prevents the spinning of fibers and reduces pulsations. Thanks to the uniform through-flow profile with short suction impulses, the MultiFoil rotor leads to improvements in sustained screen openness with the highest separation rate.

          In addition, the concept causes lower pulsations and longer basket service life. Due to the oblique arrangement of the short blades, the rotor is noticeably less susceptible to spinning. Frequently, the rotor speed can be reduced, thereby fiber-preserving and energy-saving screening becomes possible. MultiFoil rotors were developed for use in stock preparation and approach flow and can be used for Voith screens and machines of other manufacturers.
