The grain is fed from a hopper into a "shoe", a wooden trough that controls the flow of grain into the hole in the centre of the runner (top) stone.The Art of the Millstones, How They Work,Technically the millstones will do some grinding of the grain without anything on the grinding surface. Some say that porous opening in the French millstones are enough to create the grinding action between two millstones without dress. And then, of course, the rest is left up to the art of the miller how he maintains his mill and the millstones.
