  • Small-Scale Tests to Characterise Ore Grindibility

    The Bond rod mill grindability test is performed similarly to the ball mill test. The feed sample is stage-crushed to ½" (12.5mm) and the test is run under a 100 circulating load. The test can also be closed with various sieve sizes but for AG/SAG mill analyses the standard 14-mesh (1.18mm) sieve is typically used. The rod mill work index is
