  • Comminution Circuits for Gold Ore Processing - ScienceDirect

    Both AG/SAG mills and HPGRs are used over a range of comminution sizes. AG/SAG mills are used in primary milling applications but achieve both coarse particle breakage and fines production—relative to conventional crushing circuits, the product of AG/SAG circuits typically generate more fines. HPGRs are most typically used as a stage of comminution, but have been broadly …

  • Mining comminution – crusher, ball mill, and advanced ...

    Not surprisingly, comminution is a huge expense. After all, we're crushing rocks here. Interestingly enough, the crushing isn't always the most expensive part of crushing. Crushing machinery, particularly the SAG mill is massive, and much of the expense of running the mill comes from powering the movement of this giant mass of steel.


  • How to ensure energy efficiency in mining 1/4: Comminution ...

    Comminution machines can be much more energy-efficient if they target a smaller size range, i.e. F80 to P80. Therefore, a really energy efficient circuit may mean three stages of grinding instead of only two and each stage can be slightly smaller and more efficient than one big one e.g. a SAG mill (or HRC ) followed by a ball mill and with a ...


  • SAG Mill Grinding Circuit Design

    Relative to other comminution machines in the primary role. SAG mill operation is more dynamic, and typically requires a higher degree of process control sophistication. Though more complex in AG/ SAG circuits relative to the crushing plants they have largely replaced, these issues are well understood in contemporary applications.
