mill. As such, primary ball mills should be designed with the rod mill work index, and single-stage ball mills should be with both the rod mill and ball mill indices. This is because it is common to observe a difference (sometimes significant) between the rod mill and ball mill index values for a given ore type (McKen, Verret, & Williams, 2006). On

Get PriceThe work index and the size of the cyclone feed will determine the ratio of ore that is returned to the ball mill for further grinding. A ball mill operates more with the grinding surface action of the balls than the impact form of grinding that the rod mill uses. Taking this into account you can see that if the rod mill doesn't reduce the ...

Get PriceMill load or charge volume is the cumulative sum of the grinding media, process water and ore. The grinding media constitute the bigger percentage of the mill load. Empirical information show that 40% load by volume of ball mills result in optimum operation or grinding as supported by Erdem [3], Yang & Li [4] and Bernard et al [5].
