🛞Here we see the mechanism of an old windmill. The wind turns the mill's blades, which are connected to a toothed wheel. This toothed wheel is connected to another wheel, called a crown, which turns the mill's shaft. The shaft is connected to a grinding stone, which is pressed against another fixed stone, grinding the grains into flour. #windmillmechanism #ancientwindmill #windmilltechnology #windmills #mechanicalwindmill #grainmills #historicwindmill #windmillinterior #windmilldesign #molinomechanism #windenergy #renewableenergy #windmachinery #windmillblades #windmillreconstruction #windmillsociety #windmillstudies #heritagewindmill #windpower #windmilling #Sonya350 #vmribeiro
