Mill (grinding) - Wikipedia
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 or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().Ball mill, mineral ball mill, gold ball mill, ball mill,,Working principle. Ball mill grinding machine is a kind of horizontal drum-type grinding mill with external gear and double bins.
