Fine grinding circuit process improvement at the Karara ...

The Karara Mine concentrator commenced operation in November 2012 to produce high-grade magnetite concentrate. 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.

Grinding Circuits - na.srk

Initially faced with a blend of primary and oxide ore, the circuit achieved in excess of 320tph until the oxide was depleted, leaving only the much harder primary feed. The 2.0MW semi-autogenous grinding (SAG) mill and 3.7MW ball mill was assisted by a 150kW pebble crusher, but the power limitation of the SAG mill resulted in a drop in throughput.

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 (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
