Mill (grinding)
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (, via a hand crank), working animal (, horse mill), wind or water ().
