Sluice
A sluice (slus ) is a water channel containing a sluice gate, a type of lock to manage the water flow and water level. It can also be an open channel which processes material, such as a river sluice used in gold prospecting or fossicking. A mill race, leet, flume, penstock or lade is a sluice channeling water toward a water mill. The terms sluice, sluice gate, knife gate, and slide gate are used interchangeably in the water and wastewater control industry. "Sluice gate" refers to a movable gate allowing water to flow under it.
Tide mill
A tide mill is a water mill driven by tidal rise and fall. A dam with a sluice is created across a suitable tidal inlet, or a section of river estuary is made into a reservoir. As the tide comes in, it enters the mill pond through a one-way gate, and this gate closes automatically when the tide begins to fall. When the tide is low enough, the stored water can be released to turn a water wheel. Tide mills are usually situated in river estuaries, away from the effects of waves but close enough to the sea to have a reasonable tidal range.
Stamp mill
A stamp mill (or stamp battery or stamping mill) is a type of mill machine that crushes material by pounding rather than grinding, either for further processing or for extraction of metallic ores. Breaking material down is a type of unit operation. A stamp mill consists of a set of heavy steel (iron-shod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft.
Quern-stone
Quern-stones are stone tools for hand-grinding a wide variety of materials. They are used in pairs. The lower stationary stone of early examples is called a saddle quern, while the upper mobile stone is called a muller, rubber or handstone. The upper stone was moved in a back-and-forth motion across the saddle quern. Later querns are known as rotary querns. The central hole of a rotary quern is called the eye, and a dish in the upper surface is known as the hopper. A handle slot contained a handle which enabled the rotary quern to be rotated.
Reverse overshot water wheel
Frequently used in mines and probably elsewhere (such as agricultural drainage), the reverse overshot water wheel was a Roman innovation to help remove water from the lowest levels of underground workings. It is described by Vitruvius in his work De architectura published circa 25 BC. The remains of such systems found in Roman mines by later mining operations show that they were used in sequences so as to lift water a considerable height.
Hammermill
A hammer mill is a mill whose purpose is to shred or crush aggregate material into smaller pieces by the repeated blows of little hammers. These machines have numerous industrial applications, including: Ethanol plants (grains) A farm machine, which mills grain into coarse flour to be fed to livestock Fluff pulp defiberizing Fruit juice production Grinding used shipping pallets for mulch Milling grain Livestock, poultry, and aquatic feed production Sawmills, size reduction of trim scrap and planer shavings into boiler fuel or mulch Shredding paper Shredding scrap automobiles (see automotive shredder residue) Shredding yard and garden waste for composting Crushing large rocks In waste management The basic principle is straightforward.
Ship mill
A ship mill, more commonly known as a boat mill, is a type of watermill. The milling and grinding technology and the drive (waterwheel) are built on a floating platform on this type of mill. Its first recorded use dates back to mid-6th century AD Italy. Between barge and boat well is the undershot water wheel, which is driven by the flowing water of the current. There is also evidence of water mills for which both sides had a narrower water wheel, similar to an old paddle steamer.
Vosges
The Vosges (voʊʒ , voʒ; Vogesen voˈɡeːzn̩; Franconian and Vogese) are a range of low mountains in Eastern France, near its border with Germany. Together with the Palatine Forest to the north on the German side of the border, they form a single geomorphological unit and low mountain range of around in area. It runs in a north-northeast direction from the Burgundian Gate (the Belfort–Ronchamp–Lure line) to the Börrstadt Basin (the Winnweiler–Börrstadt–Göllheim line), and forms the western boundary of the Upper Rhine Plain.
Paper mill
A paper mill is a factory devoted to making paper from vegetable fibres such as wood pulp, old rags, and other ingredients. Prior to the invention and adoption of the Fourdrinier machine and other types of paper machine that use an endless belt, all paper in a paper mill was made by hand, one sheet at a time, by specialized laborers. History of paper Historical investigations into the origin of the paper mill are complicated by differing definitions and loose terminology from modern authors: Many modern scholars use the term to refer indiscriminately to all kinds of mills, whether powered by humans, by animals or by water.
Noria
A noria (ناعورة, nā‘ūra, plural نواعير nawāʿīr, from ܢܥܘܪܐ, nā‘orā, lit. "growler") is a hydropowered scoop wheel used to lift water into a small aqueduct, either for the purpose of irrigation or to supply water to cities and villages. The English word noria is derived via Spanish noria from Arabic nā‘ūra (ناعورة), which comes from the Arabic verb meaning to "groan" or "grunt", in reference to the sound it made when turning. The term noria is commonly used for devices which use the power of moving water to turn the wheel.
