Grain Elevator
A grain elevator or grain terminal is a facility designed to stockpile or store grain. In the grain trade, the term "grain elevator" also describes a tower containing a bucket elevator or a pneumatic conveyor, which scoops up grain from a lower level and deposits it in a silo or other storage facility. In most cases, the term "grain elevator" also describes the entire elevator complex, including receiving and testing offices, weighbridges, and storage facilities. It may also mean organizations that operate or control several individual elevators, in different locations. In Australia, the term describes only the lifting mechanism. Before the advent of the grain elevator, grain was usually handled in bags rather than in bulk (large quantities of loose grain). The Dart elevator was a major innovation—it was invented by Joseph Dart, a merchant, and Robert Dunbar, an engineer, in 1842, in Buffalo, New York. Using the steam-powered flour mills of Oliver Evans as their model, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The paddle wheel was attached to a shaft which was, in turn, attached to the centre of the millstone called the "runner stone". The turning force produced by the water on the paddles was transferred directly to the runner stone, causing it to grind against a stationary "Mill machinery#Watermill machinery, bed", a ...
