A mill ( Old High German muli ; from Latin molina or Latin molere for grinding) is a system, a machine or a device to crush lumpy feed material into a fine or finely grained end product. Therefore, apart from a shredding device, there is often a device for size separation ( sieving , sifting ). If the requirements for the degree of fineness of the end product are lower, crushers are used for size reduction.
All technical processes (acceptance, cleaning, grinding , sifting, transport , storage, packaging) are summarized under the term milling technology . Teaching and research on mills and milling (terminology, technology, ecology, ethnology, economics, history, law, protection, conservation and restoration and their aesthetic values) is called molinology .
The history of the mills
Millstones were part of the Mesolithic culture even before the transition to a productive economy ( Neolithic ) . The already well-known mortar was later replaced by hand-operated rotary mills. In Roman times, large mills ( Göpel ) are known from Pompeii , for example , which were operated with mules . Hydropower has been used since Roman times. The Roman engineer Vitruvius planned the mills, for example the Karlsmühle as a stone mill for cutting marble blocks on the Ruwer near Trier / Mosel . According to Örjan Wikander, the Karlsmühle is the oldest mill north of the Alps . A water mill from the Merovingian era was discovered in 1993 in the Paartal near Dasing; it is from the year 744 AD. Another early mill is from 833 AD; it was excavated in the Rotbachtal near Erftstadt-Niederberg. Wind power has been used since the Middle Ages .
