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.

All I can report is the setting of my grinder. The Kinu M47 adjusts via a fine threaded (0.5mm pitch) machine screw so each full rotation (+100 setting) is a distance of 500µm vertical travel. Since it is a conical burr the change in burr separation is some fraction of that distance, a function of the burr angle. The zero on my grinder is not ...
