Mill grinding - Wikipedia

2020-6-16A 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 processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand e.g., via a hand crank, working animal e.g., horse mill, wind or water .
