Windmills were initially used for milling, hence 'mills'. A large round heavy stone is turned by the wind powered wings and grinds against another stationary stone beneath it. The grain or corn is fed between the stones and ground into flour. It's dusty work, you definitely wouldn't want to live in a flour grinding mill.
