MillstoneWikipedia
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.
