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 ().

Fine grinding circuit process improvement at the Karara , The circuit consists of three stages of comminution plus magnetic separation at each stage for early gangue rejection High-Pressure Grinding Rolls (HPGRs) are used for fine crushing, followed by ball mills and TowerMills in secondary and fine grinding duties respectively In.

Grinding circuit design tools, including for SAG mill-ball mill circuits, and geometallurgy energy models are available to subscribers. The online library of technical articles contain several papers on metallurgical topics including comminution modelling, mass balance calculations and laboratory comminution testwork program information.

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.

Ball Mill Design/Power Calculation.
