  • Evolution of SAG Mill Process Control at the Xstrata

    Originally commissioned as a Fully Autogenous Grinding (FAG) circuit in 1997, preparations to convert the Katinniq Concentrator Mill to SAG had in fact commenced as early as 1999, but were halted owing to alternative process improvements which achieved up to1Mtpa as early as 2000.

  • What's the Difference Between SAG Mill and Ball Mill

    SAG mill is usually used to grind large pieces into small pieces, especially for the pre-processing of grinding circuits, thus also known as primary stage grinding machine. Based on the high throughput and coarse grind, AG mills produce coarse grinds often classify mill discharge with screens and trommel.

  • Advanced Controller for Grinding Mills: Results from a

    We describe an advanced multivariable controller for grinding mills which will, in spite of the severe disturbances in a mining environment, significantly improve throughput while maintaining product particle size. Some grinding operations are subjected to power excursions or spillage (such as in Semi-Autogenous and Autogenous mills), uncertainty in measurement, low ore bin, centrifuging and so on.

  • What's the Difference Between SAG Mill and Ball Mill

    The working principle of the self-grinding machine is basically the same as the ball mill, the biggest difference is that the sag grinding machine uses the crushed material inside the cylinder as the grinding medium, the material constantly impacts and grinding to gradually pulverize. Sometimes, in order to improve the processing capacity of the mill, a small amount of steel balls be added

    A review of recent concentrator start-ups has been done to examine the methods that were used to design the grinding circuits for these new plants and the results achieved. A number of these start-ups were reported at SAG 2011. Large differences between design tonnage and actual tonnage were reported, with actual tonnage both above and below the design target by wide margins. This paper will

  • Grinding Mineral Processing

    The ball mill is the fine grinding machine connect the SAG or AG mill and flotation machine. Ball mills produce fine particles with a uniform size for flotation, its grinding medias commonly are steel ball. The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but gradually wear out.
