operation of SAG mills. SAG mills are currently the technology of choice in hard rock milling operations for reducing primary-crushed ore to ball mill feed. In recent years, the trend has been towards larger-sized SAG mills with diameters of 10.4 m (34 ft) and above, with the largest being 12.2 m (40 ft) in

The figure to the left shows the typical application ranges for ball mills and stirred mill. The Vertimill is always more efficient than a ball mill with energy savings ranging from 30% to greater than 50%. The transition point from the Vertimill to an SMD varies depending on the ore properties but generally is in the range of 20 to 40 microns.
In multi-stage ABC/SABC circuits, the AG or SAG mills are in closed circuit with screens and pebble crushers. The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill.
For example, Berezitovy's SAG mill was stopped at 9 a.m one day for an inspection, and allowing for brief ventilation, two technicians then entered the mill. Wear on the metallic part of the lining was measured using an ultrasonic device, while the remaining thicknesses of the rubber/Poly-Met parts were measured with a special gauge.

Figure 2: SAG Mill Crash Stop on 10/8/2003 Crash Stop #2 – March 3, 2004 Please refer to Figures 3-5. This crash stop was done on severely SAG mill limiting ore that typically averaged 360-390 dry tph. In comparison, the worst case SAG mill limiting ore type throughput is 8,160 dry tons per day (340 dtph).
The final plan was to increase the ball charge in the SAG and ball mill to 10% v / v and 27% v / v, respectively; set the upper limit of the operating power in the ball mill to 5800 kW; use a TRIO TC Series crusher (without a power-/feed rate–controlling device, but with a feed bin) to crush pebbles for recirculation back to the SAG mill feed ...

Aug 25, 2014· In our recent conversation, Prof. Alban Lynch was very sceptical about where semi-autogenous grinding (SAG) mills have gone, and thinks they have taken us along the wrong track. He feels that they may be attractive in terms of high productivity, but says that "their energy efficiency is poor, and I feel that these immense machines are going to turn into very large ball mills".
the influence of these factors on speed, lining board, fill level ratio, and steel ball diameter of a SAG mill. Li [7] controlled the cone crusher's eccentric speed and closed side setting (CSS) parameters in the semi-autogenous grinding process by dynamically modeling the SAG mill-pebble crusher loop to improve the SAG mill throughput.
