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 ().
About the mill process Grinding is the major part in milling costs The choice of grinding technology is crucial, Boliden type of autogenous grinding (AG) has proved to be the most cost efficient Semi autogenous grinding (SAG) is by far the most used technology Flotation separation, based on surface chemistry, is the outmost important .
