Research of the MSL-14K mill applicability to determine the Bond ball mill work index

The article discusses the study of the possibility of applying non-standard mill MSL14K for the Bond ball mill test. As a result of ore grinding experiments, the Bond ball mill work index was determined by the adapted methodology for the ball mill MSL-14K. A modified equation has been proposed to calculate the Bond Ball Grinding Index (BWI), that considers the ratio of the MSL-14K mill net grinding power to the net grinding power of Bond ball mill. It was shown that the net grinding power in the Bond ball mill under standard conditions is 144,5 W, the MSL-14K mill under specified conditions is 81,5 W. Four types of ores of different mineral composition (oxidized ferruginous quartzites, gold-sulfide, sulfide copper-nickel and sulfide copper types) were tested using the standard Bond ball mill and MSL-14K mill. As a result, the indexes of the investigated ores were determined with the relative error not exceeding 4,5%, that shows the MSL-14K mill applicability to determine the Bond ball mill work index. Compared to methods for determining the working index of Bond ball mills that allow the use of mills other than Bond mills, the resulting approach has shown the best results and can be recommended as a replacement for these methods.
