exhibits many of these aspects. Maintaining the SAG mill weight at the optimum value is critical for achieving maximum grind rate efficiency and mill production (Powell,, van der Westhuizen,, Mainza, 2009). However, SAG mill weight is difficult to control as the dynamic response changes as the mill approaches maximum capacity.
Unfortunately I have a program for SAG mills and grinding circuits. Computational testing showed that: Capacity of SAG Mills can increase to 10000 t/h. The number of ball mills should be 24. The capacity of the SAG mill with precrushing by 2030% more than the SAG mill with the crashing critical size.
Key Benefits. Optimise your mill capacity and throughput. Increase liner life and cut replacement downtime. Cut energy costs. Reduce safety risks to employees. Products. Reduce downtime, save on energy costs and increase throughput and capacity in your SAG mill.
Product Size: All passing 6 mesh with 80% passing 20 mesh. Net power from pilot plant: KWH/ST. Mill, gear and pinion friction multiplier: Mill Power required at pinionshaft = (240 x x ) ÷ = 5440 Hp. Speed reducer efficiency: 98%. 5440 Hp ÷ = 5550 HP (required minimum motor output power).
AG mills (or SAG mills with low ball charges) are often used in singlestage grinding applications. Based on their higher throughput and coarser grind relative to AG mills, it is more common for SAG mills to he used as the primary stage of grinding, followed by a second stage of milling. AG/SAG circuits producing a fine grind (particularly ...
A DSM approach for a copper SAG mill operation is seen in Pamparana et al. (2017) by using stockpiles of mineral with different hardness, in order to feed the SAG mill ore, depending on the energy cost. In Pelzer et al. (2008) a DSM approach was studied for four South African gold mines and successfully achieved financial savings.
To Improve SAG Mill Tonnage but at the risk of being laughed at, another option not used much is to treat the SAG as an AG mill. Use the hard ore as the main grinding media. A fully autogenous (AG) circuits can operate at much lower operating costs, but with limited throughput. The control of AG mills, fed by hard ores and soft components of ...

In continuous wet ball mills, the composition of feed (hard ore or soft ore) to the mill varies continuously, leading to uncontrolled grinding in ...
In a largescale operation, feed ores are introduced into the AG/SAG mill in a continuous mode at a given flow rate to replace the discharging slurry. Nonetheless, the variations in the feed characteristics, typically hardness and size distribution, could cause sudden disruption to the mill operation. This would be challenging to detect in practice, owing to the hostile environment of the mill ...
