What is the function of Dutch windmill?

It was originally introduced from Germany. At first, it was just used for polishing or something. In the 16 and 17 centuries, windmills were of great significance to the Dutch economy. At that time, the Netherlands occupied a leading position in world commerce, and various raw materials were transported from various waterways to windmills for processing, including: wood from northern Europe and Baltic countries, hemp seeds and flax seeds from Germany, cinnamon and pepper from India and Southeast Asia.

There are many windmills, sawmills and paper mills in the suburbs of Rotterdam and Amsterdam, the big ports in the Netherlands. With the large-scale development of the Dutch people's reclamation project, windmills have played a huge role in this arduous project. First of all, the windmill is equipped with a movable canopy, and they install the canopy of the windmill on the roller. This kind of windmill is called Dutch windmill.

The windmills in the Netherlands, the largest of which is several stories high, have wings as long as 20 meters. Some windmills are made of a whole piece of oak. 1By the end of the 8th century, there were about 12000 windmills in the Netherlands. These windmills are used to grind grain, coarse salt, tobacco leaves, press oil, roll woolen cloth, felt, make paper and drain water from marshes. It is these windmills that constantly absorb water and drain water, ensuring that two-thirds of the country's land is free from destruction and the threat of artificial fish and turtles.

Since the 20th century, due to the development of steam engines, internal combustion engines and turbines, the ancient windmills that rely on wind power generation were once bleak and almost forgotten. However, because windmills use natural wind power, there is no danger of pollution and exhaustion, so they are not only used by Dutch people, but also become a new energy source, which deeply attracts people.
