The Mill at Anselma has three pairs of mill stones, each of which consists of a rotating runner stone and a stationary bedstone directly beneath it. The grain is loaded into a hopper, part of an assembly called the millstone furniture, which feeds it through a hole, or eye, in the center of the runner stone where it then enters the small space between the stones, where it is ground. The spacing between the stones, controlled by the miller, determines how coarse or fine the meal is ground.
