SAG Mill Grinding Circuit Design - 911metallurgist
A small steel charge addition to an AG mill can boost throughput, result in more stable operations, typically at the consequence of a coarser grind and higher operating costs. An AG circuit is often designed to accommodate a degree of steel media for circuit flexibility. AG mills (or SAG mills with low ball charges) are often used in single ...
Keeping an eye out for grinding mill dropped charge and ...
For example, a large 24 foot (7.3 m) diameter ball mill charge typically weighs around 2 million lbs (907 tons). Even though Semi Autogenous Grinding (SAG) and Autogenous Grinding (AG) mill charges contains less balls and no steel balls respectively, their large mill volumes can become quite heavy as well.

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 ().
