A mill is a device, often a structure, machine or kitchen appliance, 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 ...

Autogenous grinding (AG) and semiautogenous grinding (SAG) mills use the material to be ground as the grinding media. Autogenous grinding mills use larger rocks to impact and break smaller rocks as the mill rotates. Semiautogenous mills are basically the same autogenous mills, but with the addition of balls, similar to those in ball mills.
