    SAG Mill Testing Test Procedures to Characterize Ore

    design a primary ball mill from a rod mill work index rather than a ball mill index, because the industrial mill will operate over a coarser size reduction range as measured in the rod mill test, which may exhibit different grindability characteristics than would be observed at the ball mill index range. Table 2 compares the typical range of read more

  • Work Bond Index For Ball Mill

    Work Bond Index For Ball Mill

    The simplified test method described in this paper is an alternative procedure to the ball mill grindability test. The Bond Ball Mill Work Index (BBWi) test is carried out in a standardised ball mill with a pre-defined media and ore charge. The Work Index calculated from the testing can be used in the design and analysis of ball mill circuits ... read more
