Comparative assessment of the Bond Ball Mill Work Index tests

The article presents the review, studies and classification of the existing methods of the Bond Ball Mill Work Index determination. The scope of the analysis embraces the methods of Aksani and Sönmez, Todorović, Berry and Bruce, Horst and Bassarear, Ahmadi, Kapur, Gharehgheshlagh, Lewis, Magdalinovich, Karra, Smith and Lee, Armstrong, as well JKTech and Aminpro approaches. The deviations of the data of these methods from the actual values of the Bond Ball Mill Work Index are reported together with the approximate man-hours and equipment involved in the testing procedures. Modifications are proposed for the methods of Kapur and Ahmadi toward the higher accuracy of the results. The recommendations are given for selecting the Bond mill revolutions in the first milling cycle for apatite–nepheline, copper– nickel and iron ore for the sieve size 106 μm. An original procedure chart is proposed for choosing the determination method of the Bond Ball Mill Work Index for various initial conditions.

Keywords: Bond Ball Mill Work Index, grindability, ball milling, ore testing, energy input in milling, physical and mechanical properties of ore, laboratory-scale studies, ore pretreatment, Bond Ball Mill Work Index determination procedures, man-hours.
