  • The history and processes of milling

    The new mode of milling was much faster and therefore more economical than stone milling had been. In the roller milling process, the grain is ground into middlings, which are then sifted by hand and reground. The extensive amounts of sifting to remove the bran and the germ required a large labor force.

  • The Pulp and Paper Making Processes

    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.
