Optimization Solutions for Pulping
Get the best pulp quality
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.
Rotors and screen plates
We offer components, spare and wear parts for maintenance and optimization purposes for the following machines:

The new design of the screen plate 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.

Screen plates material quality
Screen plate material for all kind of screen plates is available in four qualities to match the customers operation condition, which means chemical load and raw material.
- Standard: The basic solution
- Comfort: Most common quality with original equipment
- Premium W: For highest abrasive wear, low chemical load
- Premium C: For high abrasion and high chemical load
Progroup Paper PM1 GmbH has been successfully utilizing CurvedBar technology in their CombiSorter, leading to significant improvements such as enhanced running properties, reduced screen plate wear, and increased operational stability.

Rebuild of pulping systems
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.
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.
