### 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.

01-01-2009· A Bond Ball Mill Work Index test is a standard test for determining the ball mill work index of a sample of ore. It was developed by Fred Bond in 1952 and modified in 1961 ( JKMRC CO., 2006 ). This index is widely used in the mineral industry for comparing the resistance of different materials to ball milling, for estimating the energy required for grinding, and for ball mill scale-up.
