Bond Rod Mill Work Index, RWi, kWh/t 18.1 Table 1. Example of AG/SAG Ball Mill Circuit Wio Calculations [1] [2] ABstrAct Optimum use of power in grinding, both in terms of grinding efficiency and use of installed capital, can have a large effect on profitability. Mill operators have long used operating work indices to evaluate grinding circuit efficiency, with great utility. Operating work

Commentary on the apparatus of the Bond rod mill work index

A "Bond" rod mill work index is to be determined in an apparatus with a wave liner. The author is aware of four laboratories that offer a rod mill work index test where the lining of the mill is either smooth, or smooth with a small number of primitive lifters that do not constitute a wave liner (one of the four laboratories is known to be investigating replacing the liner with a wave

Rapid determination of Bond rod-mill work index

Generally, Bond work index is a common method for selecting comminution equipment as well as estimation of grinding efficiency and calculating required power. In the current research, a simple, fast and accurate procedure is introduced to find the rod-mill work index based on the conventional Bond work index. The grinding experiments were carried out on four typical samples of iron, copper

The Bond rod-mill work indices obtained by this method were compared to those of standard Bond work indices with having different test-sieves. The comparison of two methods based on paired t-test showed that differences of mean values for Wi and Gi are not significant in 95% condence level. Moreover, comparing the condence intervals for the shortened method and Chongbo and Bingchen method
