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. The simplified test method described in this paper, which is used at Anaconda Research Center to approximate the work index, is an alternative procedure to the ball mill

Ball Mill Bond Work Index: WiB = kWh/st Rod Mill Bond Work Index: WiR = kWh/st Impact Bond Impact Index: WiI = kWh/st SAG Power MEI Online Bond Work Index An abreviated test that did not reach steady state as a Bond Work Index does would only be mill sizing etc.
The ball mill work index laboratory test is conducted by grinding an ore sample prepared to passing mm (6 mesh) to product size in the range of 45150 #181;m (325100 mesh), thus determining the ball mill work index (Wi B or BWi). The work index calculations across a narrow size range are conducted using the appropriate laboratory work index determination for the material size of interest, or by
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 FC Bond Mill was designed by F. C. Bond for use in determining the Bond Ball Mill Index, a measure of grindability and power required to mill various ores. FC Bond Mills are used in laboratories throughout the world. A copy of Fred C. Bonds Method of Crushing and Grinding for determination of the Bond Index is included with each mill. This Ball Mill can be used continuously or it can be used for any number of
