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.

• 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

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.

For their stock preparation Fripa Papierfabrik Albrecht Friedrich KG uses Voith Pluralis refiner fillings.

The Varel paper and board plant has been using TheWall since May 2016. Hartmut Langner, paper production foreman at Varel, explains why the company was looking for an alternative to the previously used disperger filling and why the decision was made to go with TheWall from the Voith product portfolio.
