The Bond Ball Mill Work Index (W i) was measured as 24 kW h/t at a test screen size of 106 μm. The feed top size determines the largest ball size required for particle breakage. Bond found that for a given feed size the largest size ball required could be estimated using Eq.
Bond Ball Mill Test Procedure. 3 index bond ball mill . The standard Bond Ball Mill Work Index test procedure is firstly to stage crush the feed to minus 3 35mm and size a representative sample The test then involves a series of batch grinds in a standard Bond mill A Bond mill is 0 305m by 0 305m with rounded corners a smooth lining and runs at 70rpm The charge consists of 285 balls weighing a ...

and ball mill bond work index, the low JK Axb and Ta values and the high UCS data are indicators of resistance to breakage in a SAG mill. III-96 Crushing work indices greater than 30 kWh/t are typical. On the basis of the benchscale data, a traditional SABC circuit was expected to consume approximately 30 per cent more power than typical "Bond"
