The Pulp and Paper Making Processes

In the stone groundwood process, debarked logs are forced against rotating stone grinding wheels that are constantly washed by a stream of water. The ground pulp is then screened to remove course debris, thickened, and stored for the papermaking process. Chips are used to produce refiner pulp and thermomechanical pulp. In both processes the ...
