The picture illustrates the steps involved in making pulp and paper.
Overall, it is a linear process involving several stages in the production of pulp. The pulp produced is then used to make two different types of paper for various purposes, such as boxes and printing.
Firstly, the primary material needed for the production of pulp is trees. The first step is cutting the trees into logs. In the next stage, the logs are cut into chips using a machine, and these chips can also be purchased. The chips are then processed in a digester, after which they are washed. This process produces cleaned pulp, which then passes through a pulp screen.
Secondly, the pulp screen can be used to produce rough paper for boxes or refined paper for printing. For rough paper used for boxes, the process starts with a pulp former, followed by pulp dryers. Next, the pulp is wound onto a pulp reel, then cut using a pulp cutter to produce paper bales.
Lastly, the production of refined paper for printing from the pulp screen involves five stages: pulp cleaners, pulp dryers, pulp presses, paper dryers, and finally the production of paper rolls.
