dramatic. In the stone groundwood process, de-barked logs are forced against rotating stone grind-ing 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 paper-making process. Chips are used to produce refiner pulp and thermomechanical pulp.
