[PDF] A quick method for Bond work index approximate value ...
The Bond work index is a measure of ore resistance to crushing and grinding and is determined using the Bond grindability test. Its value constitutes ore characteristic and is used for industrial comminution plants designing. Determining the Bond work index value is quite complicated, timeconsuming and requires trained operating personnel and therefore is subjected to errors.

The optimization of comminution circuits has traditionally relied on well-accepted comminution laws and ore hardness and grindability indices for ball/rod mills [9,10] and SAG mills [11,12,13].These comminution models are routinely used for optimized grinding circuit design, using averages or ranges of ore hardness tests of the mineral deposits to be extracted.

Bond's methodfor ball mill scale-up only gives the mill power draw for a given duty. This method is incompatible with computer modelling and simulation techniques. It might not be applicable for the design of fine grinding ball mills and ball mills preceded by autogenous and semi-autogenous grinding mills. Model-based ball mill scale-up methods have not been validated using a wide range …

Small-Scale Tests to Characterise Ore Grindibility
The Bond rod mill work index is used to calculate the power requirement at intermediate size, i.e. from 12.5mm to about 1mm. The test has been mainly used for the design of rod mills or primary ball mills, but it can also be used along with the other Bond tests (BWI and cWI) for SAG mill design using semi-empirical relationship [6].
