Figures 8 and 9 on the right show results from a gold plant's SAG mill achieved with MillStar's Segregated Ore Feed Controller combined with the Power Optimiser: • The standard deviation of the mill feed control is greatly reduced. • The cyclone feed is more stable, allowing for consistent size separation and feed to downstream processes.
The Manta Cube ® system can be used to control various processing units and has been successfully used for SAG Mill Control, Ball Mill Control, Flotation Control, Thickener Control, CCD Control .
movement within SAG mills. The concepts for operating SAG mills have been inherited almost entirely from conventional ball mills. However, these mills operated under a constant ball load and at a fixed speed, the slurry load and properties being the main sources of concern. Under these relatively stable
This would be achieved by connecting the expert system to the highest level of control ie provide the set points for the controllers (Elber, 1989). Over the last year or so further Help packages have been implemented. These are:a) HelpSAG Designer - used by Morgardshammar, a leading Swedish mill manufacturer, for optimizing SAG/Ball Mill circuits.

Oct 12, 2017· SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially.

semi-autogenous (SAG) mill and two ball mills, each with 13 megawatts (MW) of installed power, was expected to be SAG mill limited when treating competent basement rock. Ausenco Services Pty Ltd (Ausenco), was engaged to help optimise and enhance the productivity of the Phu Kham comminution circuit over an eight-month period.
That does not mean that the preference is speed control over feed rate control. Each ore is different and each plant is different. As equipment designers, we have to provide each of the features that the operators could use to optimize their process. In my experience, SAG Mills are normally variable speed, and Ball Mills are normally fixed speed.
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 .
In addition to the new process equipment, the SAG mill was commissioned with all controls implemented on the new PLC software platform. This removed the control strategy limitations previously described. Additional mill control loops and measurements now included: - Mill feed tonnage (automatic PI control – operator or remote set-point from mill

and the broader holistic approach to mill control are discussed. The ROM SAG mill circuit—a brief description The typical ROM SAG mill circuit is depicted in Figure 1. The circuit is usually closed with either a screen or, more commonly, a cyclone for product size classification. The focus of control can be divided into two parts, viz. the
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. A diagram of types of AG/SAG ...
