SAG Mill Grinding Circuit Design. 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.

Autogenous grinding (AG) and semi-autogenous grinding (SAG) mills are installed in the majority of comminution circuits in the mining industry. It is known that AG/SAG mill operation varies with the properties of ore that is fed into it and therefore, it is desirable to achieve optimal mill performance by understanding how the mill responds to operating parameters. However, the

In ball mills, steel balls or hard pebbles to break particle based on impact and attrition. A rotating mill charged with media and ore is lifted against the inside perimeter. Some of the media falls and impacts the ore particles at the bottom of the mill. The rest of the media cascades and, in the process, creates particle breakage by attrition.
