A gristmill (also: grist mill , corn mill , flour mill , feed mill or feedmill ) grinds cereal grain into flour and middlings . The term can refer to either the grinding mechanism or the building that holds it. Grist is grain that has been separated from its chaff in preparation for grinding .
88-409: Brockerhoff Mill , also known as Roopsburg Mill, is a historic grist mill located at Benner Township , Centre County, Pennsylvania . It was built about 1862, and is a four-story brick building on a limestone foundation. It measures 56 feet by 40 feet, and has a gable roof. Also on the property are the remains of the mill race. The mill was built by Henry Brockerhoff (1794-1878), who also built
176-457: A century there were more inventions developed and applied usefully than in the previous thousand years of human history all over the globe. The period saw major technological advances, including the adoption or invention of windmills , watermills , printing (though not yet with movable type), gunpowder , the astrolabe , glasses , scissors of the modern shape, a better clock , and greatly improved ships. The latter two advances made possible
264-414: A comprehensive production of alcohol. Food production also increased during this time as new ways of farming were introduced, including the use of a heavier plow, horses instead of oxen, and a three-field system that allowed the cultivation of a greater variety of crops than the earlier two-field system—notably legumes , the growth of which prevented the depletion of important nitrogen from the soil. During

One of the main questions during this time was the problem of universals . Prominent opponents of various aspects of the scholastic mainstream included Duns Scotus , William of Ockham , Peter Damian , Bernard of Clairvaux , and the Victorines . Christian heresies existed in Europe before
440-438: A high demand for wine and steady volume of alcohol consumption inspired a viticulture revolution of progress. The relative protection from famine during this time allowed Europe's population to increase, despite the famine in 1315 that killed 1.5 million people. This increased population contributed to the founding of new towns and an increase in industrial and economic activity during the period. They also established trade and
528-413: A husk. This foundation isolated the building from vibrations coming from the stones and main gearing and also allowed for the easy re-leveling of the foundation to keep the millstones perfectly horizontal. The lower bedstone was placed in an inset in the husk with the upper runner stone above the level of the husk. American inventor Oliver Evans revolutionized the labor-intensive process of early mills at

From the mid-10th to the mid-11th centuries, the Scandinavian kingdoms were unified and Christianized, resulting in an end of Viking raids, and greater involvement in European politics. King Cnut of Denmark ruled over both England and Norway. After Cnut's death in 1035, England and Norway were both lost, and with
704-412: 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. The distance between the stones can be varied to produce the grade of flour required; moving the stones closer together produces finer flour. This process, which may be automatic or controlled by the miller, is called tentering . The grain is lifted in sacks onto
792-581: A percentage called the "miller's toll". Early mills in England were almost always built by the local lord of the manor and had the exclusive right (the right of mulcture ) to a proportion on all grain processed in the community. Later, mills were supported by farming communities and the miller received the "miller's toll" in lieu of wages. Most towns and villages had their own mill so that local farmers could easily transport their grain there to be milled. These communities were dependent on their local mill as bread

Waldo was denied the right to preach his sermons by the Third Lateran Council in 1179, which he did not obey and continued to speak freely until he was excommunicated in 1184. Waldo was critical of the Christian clergy saying they did not live according to

The Knights Templar were a Christian military order founded after the First Crusade to help protect Christian pilgrims from hostile locals and highway bandits. The order was deeply involved in banking, and in 1307 Philip

During the High Middle Ages Lithuania emerged as a Duchy of Lithuania in the early 13th century, then briefly becoming the Kingdom of Lithuania from 1251 to 1263. After the assassination of its first Christian king Mindaugas Lithuania was known as Grand Duchy of Lithuania . Unconquered during the Lithuanian Crusade , Lithuania itself rapidly expanded to the East due to conquests and became one of

Over time, any small, older style flour mill became generally known as a gristmill (as a distinction from large factory flour mills). Modern mills typically use electricity or fossil fuels to spin heavy steel, or cast iron, serrated and flat rollers to separate

Grist mill The Greek geographer Strabo reports in his Geography a water-powered grain-mill to have existed near the palace of king Mithradates VI Eupator at Cabira , Asia Minor , before 71 BC. The early mills had horizontal paddle wheels, an arrangement which later became known as
1584-544: The Carolingian Empire had been divided and replaced by separate successor kingdoms called France and Germany, although not with their modern boundaries. Germany was significantly more eastern. Germany was under the banner of the Holy Roman Empire , which reached its high-water mark of unity and political power under Kaiser Frederick Barbarossa . During the successful reign of King David IV of Georgia (1089–1125),

The Christian kingdoms took much of the Iberian Peninsula from Muslim control, and the Normans conquered southern Italy, all part of the major population increases and the resettlement patterns of the era. The High Middle Ages produced many different forms of intellectual, spiritual and artistic works . The age also saw
1760-662: The Early Middle Ages and followed by the Late Middle Ages , which ended around AD 1500 (by historiographical convention). Key historical trends of the High Middle Ages include the rapidly increasing population of Europe, which brought about great social and political change from the preceding era, and the Renaissance of the 12th century , including the first developments of rural exodus and urbanization . By 1350,

The Cistercians were known for their use of this technology in Western Europe in the period 1100 to 1350. Although the terms "gristmill" or "corn mill" can refer to any mill that grinds grain, the terms were used historically for a local mill where farmers brought their own grain and received ground meal or flour, minus
2024-664: The Fourth Crusade treacherously captured Constantinople . This severely damaged the Byzantines, and their power was ultimately weakened by the Seljuks and the rising Ottoman Empire in the 14–15th century. The power of the Latin Empire , however, was short-lived after the Crusader army was routed by Bulgarian Emperor Kaloyan in the Battle of Adrianople (1205) . The Medieval Warm Period ,

Many northern cities of the Holy Roman Empire became Hanseatic cities, including Amsterdam , Cologne , Bremen , Hanover and Berlin. Hanseatic cities outside the Holy Roman Empire were, for instance, Bruges and

It was influenced by the spiritual background of the time, being religious in essence: thin horizontal lines and grates made the building strive towards the sky. Architecture was made to appear light and weightless, as opposed to the dark and bulky forms of the previous Romanesque style . It

The flow of grain is regulated by shaking it in a gently sloping trough (the slipper ) from which it falls into a hole in the center of the runner stone. The milled grain (flour) is collected as it emerges through the grooves in

The turning force produced by the water on the paddles was transferred directly to the runner stone, causing it to grind against a stationary " bed ", a stone of a similar size and shape. This simple arrangement required no gears , but had
3080-530: The 11th century but only in small numbers and of local character: in most cases, a rogue priest, or a village returning to pagan traditions. However, beginning in the 11th century, mass-movement heresies appeared. The roots of this can be partially sought in the rise of urban cities, free merchants, and a new money-based economy. The rural values of monasticism held little appeal to urban people who began to form sects more in tune with urban culture. The first large-scale heretical movements in Western Europe originated in

Geared gristmills were built in the medieval Near East and North Africa , which were used for grinding grain and other seeds to produce meals . Gristmills in the Islamic world were powered by both water and wind. The first wind-powered gristmills were built in

The Egyptian town of Bilbays had a grain-processing factory that produced an estimated 300 tons of flour and grain per day. From the late 10th century onwards, there was an expansion of grist-milling in Northern Europe. In England, the Domesday survey of 1086 gives a precise count of England's water-powered flour mills: there were 5,624, or about one for every 300 inhabitants, and this

The Codes of Chivalry promoted the ideal knight to be selfless, faithful, and fierce against those who threaten the weak. Household heavy cavalry ( knights ) became common in the 11th century across Europe, and tournaments were invented. Tournaments allowed knights to establish their family name while being able to gather vast wealth and renown through victories. In

The most famous of the scholastics was Thomas Aquinas (later declared a " Doctor of the Church "), who led the move away from the Platonic and Augustinian and towards Aristotelianism. Aquinas developed a philosophy of mind by writing that the mind was at birth a tabula rasa ("blank slate") that was given the ability to think and recognize forms or ideas through

Catharism was a movement with Gnostic elements that originated around the middle of the 10th century, branded by the contemporary Roman Catholic Church as heretical . It existed throughout much of Western Europe , but its origination was in Languedoc and surrounding areas in southern France. The name Cathar stems from Greek katharos , "pure". One of
4400-449: The beginning of the 13th century there were reasonably accurate Latin translations of the main works of almost all the intellectually crucial ancient authors, allowing a sound transfer of scientific ideas via both the universities and the monasteries. By then, the natural science contained in these texts began to be extended by notable scholastics such as Robert Grosseteste , Roger Bacon , Albertus Magnus and Duns Scotus . Precursors of
4488-901: The belief that it is nutritionally superior and has a better baking quality than steel-roller-milled flour. It is claimed that, as the stones grind relatively slowly, the wheat germ is not exposed to the sort of excessive temperatures that could cause the fat from the germ portion to oxidize and become rancid, which would destroy some of the vitamin content. Stone-milled flour has been found to be relatively high in thiamin, compared to roller-milled flour, especially when milled from hard wheat. Gristmills only grind "clean" grains from which stalks and chaff have previously been removed, but historically some mills also housed equipment for threshing , sorting, and cleaning prior to grinding. Modern mills are usually "merchant mills" that are either privately owned and accept money or trade for milling grains or are owned by corporations that buy unmilled grain and then own

Some Catholic monastic leaders, such as Francis of Assisi , the founder of the Franciscans , had to be recognized directly by
6072-496: The old wheel mills. 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 around 10 rpm . The millstones themselves turn at around 120 rpm . They are laid one on top of

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 turning to drive other machinery. This might include driving

That trend faltered during the Late Middle Ages because of a series of calamities , most notably the Black Death , but also numerous wars as well as economic stagnation. From around 780, Europe saw the last of the barbarian invasions and became more socially and politically organized. The Carolingian Renaissance stimulated scientific and philosophical activity in Northern Europe.
