The History and Importance of Stone Milling | Royal Lee,
Since the third century B.C., the process of milling grains into flour consisted of passing whole grains through two large moving millstones. Traditionally, one of the stones turned (the runner stone) via water, animal or human power source, while the other (the bed stone) remained stationary. This method crushes the grains but keeps all the parts of the grain (the germ, bran and endosperm) intact.
