Mill power draw models
The mill power draw models are used to predict how much power will be consumed by a particular type of mill, mill geometry and set of mill operating conditions. This power is transferred to the ore and used to predict the throughput when combined with the specific energy consumption models. Models of this type do not predict the particle size ...
SAG Milling
The main drawback of SAG - high power consumption. To reduce power consumption, I think: The right determine of SAG feed size. This depends on the mill diameter and the ball size. Feed size necessary to take 80% of the maximum piece of ore that will crushed by the balls. For the big SAG more than 8 meters optimal feed size will be - 50mm.
SAG Mill Liner Design
Based on experience, mill-liner designs have moved toward more open-shell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebble-crushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of 2.5:1 and 5.0:1.
SAG Mill Testing
The SAGDesign test was developed by the SAGDesign Consulting Group (Starkey, Hindstrom & Nadasdy, 2006) and consists of a batch grinding test conducted in a 0.488m diameter SAG mill. About 10kg of drill core is required for testing. The feed is prepared to 80% passing 19mm and ground to 80% passing 1.7mm.

AG Mill and SAG Mill. The SAG mill (AG mill) has a large diameter and a small length. It looks like a flat round drum. The diameter of the SAG mill is generally about three times its length. The diameter of the hollow pivots at both ends of the barrel of a SAG mill is large. This SAG mill design can facilitate large-sized materials to enter the ...

Sag mill / Ball mill | WordReference Forums
Se que ball mill es molino de bola, pero no se qué sea un molino de bola ¿Hay alguna otra palabra para describirlo? Entiendo que sag es como una depresión, hendidura o caída debida al peso, pero no se en sí que sea 'sag mill'. También quisiera saber qué es 'tower mill', ya que molino de torre me suena muy literal. Gracias.
Unlock SAG mill capacity with process control optimisation
Advanced Process Control Systems. With systems, there is an assumption that any issues in the plant's control system will be resolved once the system is installed. However, if the in-place base layer control is operating poorly, the system is not effective at maintaining the operational targets. Any variability created from the base ...
A comparison of SAG mill power models
Gross power = 265 + 1.26 × (2,233 + 215) = 3,349 kW. The conversion between motor input (gross) power and mill shell power, described earlier, is 0.931. Therefore, the predicted power at the mill shell is 3,119 kW, which is 71 kW less than the measured shell power (3,190 kW), a difference of 2%.

Choosing a SAG Mill to Achieve Design Performance
It is an approximation or a best guess based on limited data. This equation is: y = 225 – 1.94 x (1) Where x = the load in the mill expressed as measured % by volume and y = kg/h of feed. This information is based on observed throughput reductions caused by loading the 3-ft. SAG mill to over 26% by volume.
What's the Difference Between Ball Mill, Rod Mill and SAG Mill?
Ball mill: When the particle size of the product is less than 0.5mm, the grinding effect of the ball mill is greater than that of a rod mill of the same specification. SAG mill: The SAG mill has a wide range of feeding particle sizes and can process larger minerals, but at the same time, its output particle size is relatively larger.
SAG vs. AG Mills: Understanding the Key Differences
SAG mills use a combination of steel balls and rock particles as grinding media, while AG mills use only the ore itself. Both types of mills are used for grinding ore in mineral processing operations, but SAG mills are larger in size and can grind larger quantities of ore. AG mills, on the other hand, are smaller and are typically used for ...

A data set of mill operating data is collected from published information and compared to predictions made by two published mill power draw models for SAG mills (Austin's SAG model and Morrell's C-model). A third model (Hogg and Fuerstenau) is fit to each survey and the principal fitting parameter is tabulated. Power measurement
What's the Difference Between SAG Mill and Ball Mill
The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
