  • Small-Scale Tests to Characterise Ore Grindibility

    BOND ROD MILL GRINDABILITY 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.
