However the author has developed a relationship between the Bond third theory SE values and the AGSAG SE values to enable the additional power required for AGSAG milling to be determined. AGSAG inef ciency varies according to the transfer sie
Quick method for bond work index approximate value determination. 331. The Bond work index Wi is defined in a Bond ball mill on the samples of standard sie 3.327 0 mm. In practice it
2011919The Bond Rod Mill work indices were much higher than the Bond Ball Mill work index values. Because the ores were so soft the effect of these Bond RM Wi results on required SAG grinding energy should probably be ignored for the Tenke project.

Bond F. C. Crushing Tests by Pressure and Impact Trans AIME Vol 169 1947 pp 5866. Bond Rod Mill Grindability Test. The test determines the Bond Rod Mill Work Index which is used with Bonds Third Theory of Comminution to calculate net power requirements when siing ball mills. Various correction factors may have to be applied.

2 The Bond Ball Mill Work Index is a measure of the resistance of the material to grinding in a ball mill. It can be used to determine the grinding power required for a given throughput of material under ball mill grinding conditions. It is a locked cycle test conducted in closed circuit with a laboratory screen.
Work Index. Bond estimated the amount of wear in terms of kilograms per kWh based on the abrasion index A i.e. Wet Ball Mill kg kWh 0.16A i0.015 0.33 Dry Ball Mill kg kWh 0.023A i 0.5 Replacement Ball Sie. Rowland and Kjos proposed the use of their equation for the determination of the initial and replacement media sie.
