— The ratio of steel balls in the ball mill depends on the effective length of your mill, whether it has a roller press, the size of the feed particles, the lining and structure used, the expected sieve residue fineness and ratio, how many chromium balls to operate, and the rotation speed How much and other factors make a comprehensive judgment.
— For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of 1.54 kw/t reduces the ball mill feed size to 6,500 micrometers. As a result, the mill output will increase with this reduced size to approximately 77,000 tons per day.
