The best-fit technology for each resource

    Pulping is the first step in the papermaking process, with the purpose of producing a clean fiber suspension that can be pumped forward in the process. Fibers from virgin pulp, recovered paper or paper machine broke are mixed, i.e., pulped, with water to form a suspension inside the pulper. The optimal pulping technology is selected depending on the type of furnish, production output and the contaminants in the furnish. Pulping systems for recovered paper not only disintegrate the paper and board into single fibers but also remove large non-fiber components (rejects), such as plastics or glass.

    In order to avoid breaking the rejects into too small pieces, it is important for the pulping process to find a balance between the main parameters, such as pulping consistency, temperature, retention time and chemical additives. A low amount of rejects in the pulp makes the downstream process easier and more efficient to operate.

          Since recovered paper, bales and many contaminants make the pulping process in stock preparation more difficult, a robust process and resistant machines are essential in pulping. An investment in the Intensa family from Voith is particularly worthwhile, as Voith combines robustness with low energy consumption and fiber loss.
