The basic strategy works by maximizing the SAG mill power, using a microphone or vibration sensor on the shell to indicate when the impact energy is low, and when the …

would clear, and the SAG mill would unload. This would require a decrease in mill speed to protect the liners and a severe drop in total tonnage through the circuit. A. The action of diverting of the untreated pebble load back to the SAG mill, results in a sudden increase in total tonnage to the SAG mill feed. When this happens, the base layer

Right angle SAG mill feed (eliminate one pebble recirculation conveyor) Outcomes and achievements. The key features/outcome of the optimized layout are: Coarse ore conveyor length substantially reduced; Reduced pipe rack and piping length; Five (5) set of pumps and two (2) single pumps eliminated; Four (4) pump boxes and two (2) tanks eliminated

3. It has been observed that engineers and consultants have, at times, under estimated the SAG mill specific energy for treating competent ores due to lack of relevant data for comparable benchmark operations, lack of understanding of the test work methods used by various laboratories, and poor use of packages such as JKSimMet.
