A simplistic algorithm for simulating the rod or ball mill Bond grindability test applied to ores and minerals is presented. A performance comparison between the present algorithm and a previously published algorithm by Kapur, modified in this work for a fair evaluation, is also given. A worked example is furnished for leading the reader through the various calculations.
