significant between the rod mill and ball mill index values for a given ore type McKen, Verret, amp Williams, 2006. On average, the rod and ball mill indices are essentially equal, but the ratio between the two can be quite variable. High RWI BWI ratios indicate competent ores with low ball mill hardness, while low ratios
Too low a speed and little energy is imparted on the product. Too fast and inefficient media movement known as cataracting will generate high impact but also greatly increase mill wear. Even faster speed will result in the media centrifuging inside the mill and virtually no milling or movement of media or product will occur.
