Abstract
In the Kraft process, making pulp begins by conveying wood chips of uniform size into a vessel called a digester. Once the pulp-making process is complete, the pulp is transformed into paper. However, not all mills make both pulp and paper at one location. Market pulp mills drain most of the water from the pulp on a dryer and sell it as dry sheets to other mills for papermaking. At what is called an integrated mill, where both pulp and paper are made, the pulp moves on to the paper machine. As the water is drained, the goal is to have the fibers of the cellulose cross each other and bind into a tight, even sheet. Once that's done, the sheet moves to large, cylindrical dryers. The paper is wound onto large rolls, then cut and converted to finished products.
