SAG circuits may employ low to relatively high ball charges (ranging from 2% to 22%, expressed as volumetric mill filling) to augment autogenous media. Higher ball charges shift the breakage mode away from attrition and abrasion breakage toward impact breakage; as a result, AG milling produces a finer grind than SAG milling for a given ore and ...

The Kaltech Sentinel Camera System provides the capability to look inside your mill WITHOUT removing the feed chute and other related, time-consuming tasks. Currently the simple task of inspecting of the ball charge level, or the setting of the ore charge level for efficient and safe mill relining, can take hours, requiring personnel, planning ...
Up until now, SAG mill operations have relied on forward looking predictive liner wear calculations based on historical wear to determine the liner wear and replacement schedule. This process is typically supplemented by the regular or occasional shutting down of the mill and pulling the feed chute to visually inspect, laser-scan or otherwise ...
autogenous grinding (SAG) mills. • Part 2: Using ore properties to assess the circuit specific energy. This can also include assessment of the specific energy requirements for crushing, high pressure grinding roll (HPGR), and tumbling mill processes.
Mill visuals and vitals: Aimed at improving mill reliability, this inspection focuses on catching cracks, oil contamination, and slurry leaks with minimal downtime. Mill mechanical verification: Aimed at improving mill integrity, this inspection looks for wash under trunnion liners and includes mechanical adjustments and critical torque verifications.

Mine-to-mill: The formal idea that optimal fragmentation in blasting can significantly increase the capacity (and therefore energy efficiency) of comminution processes, especially SAG mills, has been around now for 20 years and is still an important option that has not been fully exploited (e.g. Rybinski et al., 2011). 3.

of the energy required by a SAG mill. Put another way, the SAG mill energy required according to this statement, is 2.5 times more than the Ab value to produce the same degree of particle breakage. There is a speci fi c gravity factor that affects AG/SAG power draw. The lighter material, in the 2.5 specifi c gravity (SG)
A recent report by Newmont Asia Pacific summarised significant energy savings at their Jundee operation. Sag/Ball Mill Weight Control (Newmont Jundee Operations) During late 2009 and early 2010 the power draw of the SAG and Ball Mill motors at Jundee was reduced by better managing the SAG and Ball mill weight.
