Numerically, the work index is the energy required in kwh/t to reduce a given material from theoretically infinite feed size to 80% passing 100 microns. The work index of a particular material is determined in the laboratory by conducting the standard Bond grindability test. Bond developed separate tests for the rod mill and the ball mill.

Limestone Bond Ball Mill Work Index. The grinding jar for the Bond Index Rod Mill is 12 x 24 in size and has a waveshaped design At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill The Rod Mill Work Index RWI is used for particle size determination in a size range from 25 mm down to 21 mm whereas Ball Mill Work
The Bond work index determination according to the standard Bond''s test is done on all these samples with comparative sieve size of 74, 105 and 150 microns. The Bond Work Index is calculated using the formula (Bond, 1961): ( ) (1) where: W i Bond work index (kWh/t); P c test sieve mesh size (#181;m); G weight of the test sieve
The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure ), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material

Ball mill design requires a Bond work index, BWi, for ball mills at the correct passing size; SAG mill design requires an appropriate SAG test, for example, SPI (Chapter 5). Flotation design needs a valid measure of kinetics for each sample, including the maximum attainable recovery and rate constants for each mineral ( Chapter 12 ).
