Although constructed largely of wood and stone, a grist mill was a true machine and a sophisticated one at that—it converted energy to work. Usually, a horizontal axle water wheel was turned by the falling water. A series of gears then changed the direction and speed of rotation to a vertical spindle connected to the grinding stone.

Windmills do not produce electrical energy but rather use mechanical energy—originally to grind grain in grist mills. Vertical windmills, the kind familiar to rural America or Holland, use sails ...

In the vertical-wheeled watermill, the vertical, circular movement of the waterwheel was converted to a horizontal rotation through the use of a right-angle gear. The right-angle gear, invented about 270 BCE, was a transmission system consisting of two cogwheels which increased the velocity of the runner stone, thereby, generating …

The hammer mills are very common throughout Africa. As the name implies, hammers in the mill grind grains through impact.

The heart of a grist mill was its grinding stones. Grinding stones were used in pairs. The bottom stone, or bed stone, was fixed into position, while the upper stone, or runner stone, moved. The stones were connected to the power source (water or wind) by a wooden "counterwheel," or contrate wheel, wedged on the horizontal drive shaft, which

For example, a grist mill involves a power source, transmission gearing, stone grinding wheels, barrels, a building to house it all, and, of course, some sort of distribution system for the final product, or the goal, which is flour. Ultimately, technology is a human endeavor and cannot exist outside its human context.
