Middle Ages
Limited examples of gristmills can be found in Europe from the High Middle Ages. An extant well preserved waterwheel and gristmill on the Ebro River in Spain is associated with the Real Monasterio de Nuestra Senora de Rueda, built by the Cistercian monks in the year 1202. The Cistercians were known for their use of this technology in Western Europe in the period 1100 to 1350 AD. This article is 150 kilobytes or more in size. ...

Modern mills Historically gristmills contained rotating stones powered by water or by wind; later mills used steam engines for power, and modern mills typically use electricity or fossil fuels to spin heavy steel rollers. These techniques produce visibly different results, but can be made to produce nutritionally and functionally equivalent output. Mill stones are used in windmills and watermills for grinding wheat or other grains. ...

Gristmills only grind clean grains - that is, grain from which stalks and chaff have previously been removed - but some mills also housed equipment for threshing, sorting, and cleaning prior to grinding. Gristmills also ground corn into meal. Chaff is the seed casings and other inedible plant matter harvested with cereal grains such as wheat. ...

Modern mills are almost certainly "merchant mills"; that is, they are privately owned and accept money or trade for milling grains, or the corporations that own the mills buy unmilled grain and then own the flour produced. Early mills were almost always built and supported by farming communities and typically a percentage of each farmer's grain called a "miller's toll" was set aside for the miller in lieu of wages. Although gristmill can refer to any mill that grinds grain, the term historically was used to refer to a local mill where farmers brought their own grain and received the flour from it, minus the "miller's toll." [1] Modern mills use serrated and flat cast iron rollers to separate the bran and germ from the endosperm. The endosperm is ground to create white flour which may be recombined with the bran and germ to create whole wheat or graham flour. Cast iron usually refers to grey cast iron, but can mean any of a group of iron-based alloys containing more than 2% carbon (alloys with less carbon are carbon steel by definition). ...

The classical British and American mills Classical mill designs are usually water powered, though some are wind mills, or powered by livestock. A sluice gate is used to open a channel and so start the water flowing and a water wheel turning. In most such mills the water wheel was mounted vertically (i.e. edge-on) in the water, but in some cases horizontally (the tub wheel and so-called Norse wheel). Later designs incorporated horizontal steel or cast iron turbines and these were also sometimes refitted into the old wheel mills. A watermill is a machine constructed by connecting a water wheel to a pair of millstones. ...

 Glade Creek Grist Mill in Babcock State Park, West Virginia, USA, 2006 In most wheel-driven mills, a large gear-wheel called the pit wheel is mounted on the same axle as the water wheel and this drives a smaller gear-wheel (the wallower) on a main driveshaft running vertically from the bottom to the top of the building. This system of gearing ensures that the main shaft turns faster than the water wheel, which typically rotates at 10 revolutions per minute, or so.

Revolutions per minute (abbreviated rpm, RPM, r/min, or min-1) is a unit of frequency, commonly used to measure rotational speed, in particular in the case of rotation around a fixed axis. ...
The millstones themselves turn at around 120 rpm. They are laid one on top of the other. The bottom stone, called the bed, is fixed to the floor, while the top stone, the runner, is mounted on a separate spindle, driven by the main shaft. A wheel called the stone nut connects the runner's spindle to the main shaft, and this can be moved out of the way to disconnect the stone and stop it turning, leaving the main shaft going to drive other machinery. This might include driving a mechanical sieve to refine the flour, or turning a wooden drum to wind up a chain used to hoist sacks of grain to the top of the mill house. In general, a sieve separates wanted/desired elements from unwanted material using a tool such as a mesh, net or other filtration or distillation methods. ...
The grain is lifted in sacks onto the sack floor at the top of the mill. The sacks are emptied into bins, where the grain falls down through a hopper to the stones on the stone floor below. The flow of grain is regulated by shaking it along a gently sloping trough (the slipper) from which it falls into a hole in the centre of the runner stone. The milled grain (flour) is collected as it emerges through the grooves in the runner stone from the outer rim of the stones and it gets fed down a chute to be collected in sacks on the ground or meal floor. A very similar process is used for grains such as wheat, kamut, etc to make flour as well as for maize to make corn meal. For other uses, see Bag (disambiguation). ...
