The Importance of Material Grinding in Manufacturing. Apart from being used as material removal process, it is also used to sharpen the cutting edges of cutting tools and sharp objects such as knives, although the underlying process of material removal is the same, but with a different purpose – to produce a sharp edge rather than to reduce size.
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 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 ().
