A mill is a facility that processes raw materials into finished products, often using machinery. Common types of mills include grain mills, which grind grains like wheat into flour, and sawmills, which cut timber into lumber. Mills have been essential in various industries for centuries, contributing to food production and construction. In addition to traditional mills, modern variations include textile mills, which produce fabrics, and paper mills, which manufacture paper products. The operation of a mill typically involves several steps, including grinding, cutting, or refining, depending on the material being processed.
