The diagram illustrates how wood is processed to make pulp and then turned into paper for printing and box production.
Overall, it is a multi-stage process that begins with cutting down trees and ends with finished paper products.
At the first stage, trees are cut down and turned into logs. These logs are then chipped into small pieces and mixed with purchased wood chips. The mixture is placed into a digester, where it is processed to produce pulp. This pulp is then washed and screened to make clean pulp.
After that, the clean pulp can be used in two different ways. In the first production line, it is used to make rough paper for boxes. The pulp is shaped in a forming device, dried, and rolled into reels. These reels are then cut into paper bales and packed for use.
In the second production line, the clean pulp is used to make fine paper for printing. It is cleaned again in pulp cleaners, pressed in pulp and paper presses, and then dried in paper dryers. Finally, the finished paper is rolled, completing the manufacturing process.
