A mill is a facility used to grind grain into flour or meal. It typically consists of machinery that processes raw materials, such as wheat or corn, using various methods like crushing or grinding. Mills can be powered by water, wind, or electricity, and they have been essential in food production for centuries. There are different types of mills, including grist mills for grain, sawmills for cutting wood, and textile mills for processing fabrics. Each type serves a specific purpose in transforming raw materials into usable products, contributing to various industries and local economies.
