Design SAG mill production when you need it most: In day 1 ...

26% load while power peaks at about 35% load. When overloaded, a SAG mill loses coarse ore breakage and feed tonnage must be reduced to grind out the mill and resume production at a reduced rate. When operating flat out (not recommended), because ores are variable in hardness, maximum throughput varies. This may work in

KnowledgeScape

Grinding Mill Charge Detection Sensors. The throughput and efficiency of a SAG mill depends on the volumetric load: An overloaded mill has reduced coarse ore breakage, as the cascading balls and rock cannot drop far enough, reducing kinetic energy for breakage.

Autogenous and Semi-Autogenous Mills | FL

SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in the mill.

Multi-component AG/SAG mill model - ScienceDirect

The proposed multi-component AG/SAG mill model is similar to, and based on, the current JKSimMet model. ... The bulk SG in the mill load, and the coarsest 20% size (S 20) is used to calculate the average energy level (E 1), which is considered to be the same for all components in the mill. Then the SG of each component is used in Eq.

Choosing a SAG Mill to Achieve Design Performance

designing the new SAG mill chamber for optimum conditions at the design point is clearly established. For the operating load range just beyond the optimum performance conditions, a linear model was developed to assess the lost production that would result from running the mill at too high a load level.

SAG Mill Grinding Circuit Design

Grinding & Classification Circuits. ... The ball mill has higher circulation load, it generates only 30 -35% of actual fines you require to be called as product. If your product size needed is passing 45 micron, then the ball mill total discharge material will contain normally 30% of 45 micron. The rest is oversize which has to be ground ...

(PDF) Influence of feed size on AG / SAG mill performance

It is also possible to use the À1 00 fraction that shows a positive effect on the SAG mill throughput (the power consump- tion decreases, but the specific energy decreases more) because the ...

The magic of bolting for a grinding mill assembly -

Mar 17, 2020· This concept is similar to preloading bolts when assembling a mill. When you tighten the bolts, you compress the flanges (i.e. the clamped parts), and when the mill is running, any additional load on the joint will be partially distributed to further stretch the bolt, and partially to relax the joint.

SAG Mill Control at Northparkes Final

The difficulty of stabilizing SAG mill load limits the effectiveness of feedback control approaches. Control is particularly difficult during periods when the feed ore is either unusually hard or fine. There is also a strong tendency to lose control during transient periods when feed ore changes.

(PDF) Power-based comminution calculations using Ausgrind

AG/SAG mill performance is commonly measured and evaluated by means of the AG/SAG specific energy (kWh/t), which is often predominantly sensitive to varying ore properties governed by a given ...
