The arms of a mill are called blades.
A blade is an element formed by two sticks that cross each other forming a cross . As an instrument , it is used with the intention of pulling threads: that is, to form skeins .
The most common use of the notion is associated with windmills . The external apparatus of these devices, made up of arms that move by the action of the wind, is known as a blade. The arms in question, in fact, are also called blades .
Blades on windmills
Windmills are used to grind using wind energy (generated by the force of the winds). When the wind hits the blades, they move and activate a mechanism that, in turn, sets the hearth and grindstone of the mill in motion. These stones crush and pulverize the grains, achieving grinding.
The blades rotate according to the direction of the wind . That is why its orientation can generally be modified according to needs. This way it is possible to adapt the mill gear.
Fans also have blades.
Aspects to consider
In addition to everything stated above, we cannot ignore that there are also other devices that also have blades. Among those are ceiling fans and some standing ones. It is essential that the buyer pay attention to them, among other aspects, to know if it is what they need.
In this sense, it is essential that they are adequately protected, that they have the ideal number to provide the desired fresh air and that they are made with an appropriate material for their resistance.
However, it must be taken into consideration that there are also bladeless fans that are considered to be more efficient, quieter and even capable of moving a greater air flow.
There are also blades on helicopters and even on windmills or pinwheels.
