Pulp and Paper Manufacturing Processes in Papermaking Industry

How to change pulp to paper in paper manufacturing process. On the process of paper manufacturing process, in order to finally turn the pulp into paper, the pulp is fed or pumped into giant, automated papermaking machines. One common type is called the Fourdrinier machine, which was invented in England in 1807.

Basic Overview of Pulp and Paper Manufacturing Process

Pulp making can be done mechanically or chemically. The pulp is then bleached and further processed, depending on the type and grade of paper that is to be produced. In the paper factory, the pulp is dried and pressed to produce paper sheets. Post-use, an increasing fraction of paper and paper products is recycled.
