Netherland Windmill




Thank you  Kapelle.
A windmill is a machine which converts the energy of wind into rotational motion by means of adjustable vanes called sails.
The main use is for a grinding mill powered by the wind, reducing a solid or coarse substance into pulp or minute grains, by crushing, grinding, or pressing.
