andesite bond ball mill work index

  • THE BOND WORK INDEX OF LIMESTONE AND ANDESITE

    Ore grindability is represented by the Bond work index value for the purposes of the processes in mineral processing. This value is found in a laboratory Bond ball mill by simulating dry grinding in a closed circuit until the 250% circulating load has been achieved (Magdalinovic, 2003).

  • QUICK METHOD FOR BOND WORK INDEXAPPROXIMATE

    According to the Bond standard procedure, the work index is determined by simulating a dry grinding in a closed circuit in the Bond ball mill to achieve 250% circulating load (Bond, 1949, 1952, 1961). The test is performed on a raw material approximately weighing 10 kg, which coarseness is 100% -3.327 mm.
