    Efficient pulping solutions from Voith

    With the right technology, efficient pulping of virgin pulp and recovered paper in stock preparation leads to reduced specific energy consumption. In addition, bottlenecks in pulping capacity are eliminated and improvement in pulping efficiency is ensured. Our pulping rotors and screen plates meet these requirements by improving flow and pulping properties of the stock suspension.

      CurvedBar

      The new design of the screen plate for the IntensaPulper IP-R enables a clear increase in service life, resulting in fewer maintenance shutdowns. In addition, the design reduces the lateral forces on the bars. As a result, less rejects are shredded, which otherwise would have to be separated in the subsequent process at great expense. In addition, the wear on the bars is significantly reduced.

      Rebuild of pulping systems

        Voith IntensaTechnology for pulpers
        Rebuild to IntensaTechnology

        IntensaTechnology from Voith provides quick and intensive mixing of fibers in pulping. With existing LC (low-consistency) pulpers, the rotor geometry and flow characteristics of the pulp are changed, and the stock consistency is increased in a comprehensive rebuild. With the IntensaTechnology rebuild components, energy savings of up to 50% can be achieved. A doubling of pulping capacity is also possible. The rebuild to IntensaTechnology can also be done on older Voith pulpers and on pulpers from other manufacturers.

        IntensaMaXX pulper from Voith
        Rebuild to IntensaMaXX

        The particular orientation of the rotor-screen unit on the top of the asymmetrically shaped tank ensures that no vortices can form inside IntensaMaXX. Development of spinnings is thus successfully counteracted, and even maximum contaminant contents are not a problem. Reject discharge in a downward direction ensures reliable removal of contaminants. A rebuild to IntensaMaXX is worthwhile in general for capacity increase or as replacements of detrashing machines such as Fiberizer, Contaminex, CMS and CMV or machines of other manufacturers.

            Rotor refurbishment service

            Heavy contaminants in recovered paper cause wear to the working elements of your stock preparation machines. In almost all cases, proper performance of these machines depends upon maintaining the original design geometry of the working elements. Therefore, we offer a comprehensive rotor refurbishment service. Our services are applicable to all rotor types and screen plate combinations of the stock preparation equipment, irrespective of the manufacturer and type of pulper.

            Solutions for LC pulpers

              NDuraPlate B

              The kidney bean design of the holes provides significant improvements in yield, efficiency and throughput. The design features a larger working edge size of up to 75%. This improvement enables a high increase in throughput as well as optimized flake reduction. As a result of the new hole design, specific energy consumption is significantly decreased. The screen plate NDuraPlate B fits perfectly into each individual Voith pulper as well as all non-Voith pulping machines and generates a high-quality pulping result.

              IPV Rotor

              Thanks to the wider rotor blades and softer curves, the newly developed design of the IPV Rotor enables greater pumping action or circulation of the stock in the pulper vat. In combination with Voith’s NDuraPlate B screen plate, the efficient deflaking of the fibers is substantially improved, and energy savings of up to 30% can be achieved. In addition, the special material used results in long service life and lower maintenance costs.

              IntensaRotor R

              The newly designed IntensaRotor R with perfect pulping performance and the lowest (specific) energy consumption ensures optimal ragger operation due to its smooth design. In addition, its potential for up to 20% specific energy savings is impressive. A separate rotor-hub connection allows easy setting of the distance between rotor and screen plate. The pulping quality with IntensaRotor R is consistent, and the operating conditions are stable. Due to its intelligent design and low refurbishing costs, maintenance costs are minimal.

              Solutions for flat screens

                NDuraPlate D

                This screen plate consists of two levels. At the lower level, the countersunk holes represent the center of the daisy. The upper level is composed of standard holes arranged like petals around the center. In interaction with a rotor, the new adjustment creates microturbulences on the plate surface. This leads to faster and better purification of the plate. The improvements of the newly designed hole shape of the NDuraPlate D result in either a high increase of the throughput or flake and loss reduction. Production efficiency steadily increases, while the fiber percentage in the rejects remains constant. These advantages lead to significant energy savings as well as a return on investment in as little as four months.

                NDura Rotor

                With special wear-protection layers the working edges of the NDura Rotor are protected to avoid cracks in the rotor. Thus the rotor lifetime can be improved while simultaneously guaranteeing high performance and quality. Due to optimized rotor/shaft connection, maintenance costs are lower with the NDura Rotor. Furthermore, new clamping devices improve safety and minimize damage to the rotor hub and shaft.

                  Rebuild for HC pulpers

                  HelixRotor

                  For an efficient stock preparation process, minimal fiber loss and a high degree of ink particle separation are essential features of high consistency (HC) pulpers. The HelixRotor ensures gentle pulping, yet at the same time a high degree of whiteness in the final stock through high frictional forces. It also achieves a reduction of pulping time by up to 20% in batch operation. This results in energy savings, reduced consumption of chemicals and a significant productivity increase.
