a semi-autogenous (SAG) mill. AG/SAG mills are often used as the first stage in a two- or multiple-stage grinding process, where the second stage is carried out by the ball mill, but they can also be used as a one-stage grinder. The absence of, or ... Mill application features control.
Increasing liner lifter face angle from 7 to 30° increased throughput by 27%. Converting AG to SAG mills by adding 5(%) balls increased throughput by 40%. SAG milling also decreased the product size by 3%. Stability of the process was the main outcome of conversion to SAG milling.

Jan 08, 2016· In this training module, we'll cover the workings of a semi-autogenous grinding mill, or SAG mill, that's designed to be the first stage of a grinding circuit. Ore that's crushed in a primary ...
If the SAG mill is not intended to be the rate-limiting step in a process plant, then it is best to adjust the SAG load (and power) to hold a constant tonnage to satisfy another constraint elsewhere. Underground mines are an example: the hoisting capacity of the mine shaft is the rate-limiting step in the process, and the SAG mill must adapt to ...
AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill-ball circuit. All of the above contributes to
Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.
With improved SAG mill control stability, the mill load can be optimized to ... ANDRITZ AG, Stattegger Strasse 18, 8045 Graz, Austria. BrainWave is a registered trademark in Canada and the USA.

Every mining operation has a unique grinding process. has experience of over 8,000 grinding mills globally, including manufacturing and delivering the largest SAG/AG mills in the world. Our experts welcome the opportunity to assist you with circuit and circuit control design as well as start-up, operation, and optimization of your mill.
Oct 01, 2014· 2.4. Multivariable predictive control. In the present work, a three-input-three-output scheme of control was performed. The total water feed to the mill (the feed water flow rate was added to the dilution water flow rate, so they could be specified separately, but for the SAG mill model, the total water content was the variable of interest), the fresh ore feed rate, and the mill rotation speed ...
milling, where the ability to control the product size is very limited. For a given power draw (kW), the specific energy input in kWh/t input is purely driven by the AG/SAG mill throughput, which in turn is driven by the dynamic of the ore. The traditional approach to measure the .
Model Predictive Control for SAG Milling in Minerals Processing | 5 Model Predictive Control on a SAG Mill and Ball Mills The solution for the SAG Mill is an adaptive controller which controls mill load using direct mill weight measurement or indirectly from bearing oil pressure.

ABB's GMD is the most powerful mill drive system in the market to power semiautogenous (SAG), ball and autogenous (AG) mills, This 'workhorse' for grinding operations combines a robust, service-friendly and fit for purpose design to provide highest throughput, reliability .
MillStar control system has stabilised the feed to the SAG mill as well as the density at the discharge end of the SAG mill and ball mill. The FloatStar Stabilisation and Optimisation controllers have successfully stabilised and optimised the flotation circuit to ensure consistent product quality within desired specifications.
AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit.
In this case, mill speed is the primary manipulated variable used to control mill load. While there is no generic control strategy for SAG milling there is a considerable amount of reusable engineering. In contrast to an expert or black box system, the control loop approach was built using standard blocks, connected as shown.
