  • Millstone

    Millstones or mill stones are stones used in gristmills, for grinding wheat or other grains.. Millstones come in pairs: a convex stationary base known as the bedstone and a concave runner stone that rotates. The movement of the runner on top of the bedstone creates a scissoring action that grinds grain trapped between the stones.
