Corrugated board raw material:kraft liner and semichemical fluting manufacturing process

Raw materials processing of kraftliner and semichemical fluting:
The process for the production of Kraftliner and Semichemical Fluting starts with wood coming from the forest to the mill. Most of the wood is delivered to the mill in the form of pulpwood logs but also a substantial part is bought as wood chips from saw mills nearby. The pulpwood logs have to be debarked and chipped before further processing. Therefore the logs have to pass through a barking drum and a chipper. The chips produced are screened to take away wood dust formed as well as oversized chips and knots.

The oversized chips are reprocessed to get proper chip dimensions and brought back to the chip flow. The chips are stored in a chip pile before processing in the pulp department. Recovered paper The raw material for Testliner and Wellenstoff, recovered paper, is delivered as bales, and kept on stock by grade. With a pre-selection method, it is possible to determine the suitability of a certain recovered paper mix for the stock preparation and paper process. The stock preparation is done in accordance with a recipe for each paper grade and grammage. The grades of recovered paper are put on the conveyor to the pulper in the ratio mentioned in the recipe.
