Aug 25, 2014· In our recent conversation, Prof. Alban Lynch was very sceptical about where semiautogenous 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".
AG and SAG mills are extensively used in the mining industry for extracting minerals such as metals, oil shale, limestone, rock salt, coal, gemstones, dimension stones, gravel and clay. Autogenous grinding (AG) mills are tumbling mills which do not require a dedicated grinding media .
FullerTraylor SAG/AG Mills range in size from through in diameter with powers as high as 28,000 kW. Our team of product engineers continually improves SAG/AG Mill designs in order to provide the most robust, safe, and efficient grinding mills available.
The RBT provides automation and precision to the measurement of energy required to process ores, assisting in the design of the most efficient ball and AG/SAG mill for a given ore body. The RBT funnels sample rocks through channels in a spinning flywheel and uses the centrifugal force to smash them against a circular anvil at up to 160 m/sec.
's AG/SAG mills accomplish the same size reduction work as 2 or 3 stages of crushing and screening The feed size for these mills is limited to the maximum size that can be practically conveyed and introduced into the large mill feed chutes.
Model Predictive Control for SAG Milling in Minerals Processing. SAG and ball mills are generally accepted as the largest power consumers in a mining and ... media and the ore to be drawn upwards with the mill liners and tumble, causing ... material which then flows back to the mill for another pass.

In most cases AG mills are high aspect mills. The introduction and subsequent ascendancy of AG and SAG milling for comminution circuits has led to many economic advantages, from high processing capacity, energy efficiency, lower investment and maintenance cost (Nunez F and Silva D, 2011).
highly energy efficiency AG/SAG and Ball mills. To increase the energy efficiency of grinding circuits he follows holistic approach by the optimizing of material transport, charge motion and particle breakage processes. Sanjeeva is the recipient of the MIOTA (Mineral Industry Operating Technique Award) Award from the AusIMM for his

Apr 18, 2019· AG and SAG mills are extensively used in the mining industry for extracting minerals such as metals, oil shale, limestone, rock salt, coal, gemstones, dimension stones, gravel and clay. Autogenous grinding (AG) mills are tumbling mills which do not require a dedicated grinding media and use the ore itself for grinding.
AG and SAG mill circuit selection and design by simulation. The data indicated that the effect of increasing speed, ball charge or ball size in SAG mills was to increase the degree of coarse particle breakage, often with an associated reduction in the .

Accurate models of classification allow for the interaction between classifier efficiency and target product size (, P 80 or percent passing 150 μm) to be considered. This paper considers a range of circuit types and overall energy efficiency in the context of case studies where different circuit types were treating similar ore types.
Jul 01, 2010· Furthermore, HPGR technology may allow a simpler upstream process compared with AG/SAG mills. Machines have capacities up to 3000 t/h and can do similar work to an SAG mill at half the energy ...
