    Feb 27, 2019 For example, in the 1980s, the largest operating ball mill was 5.5 m in diameter by 7.3 m in length driven by a 4 MW motor. Today, ball mills of 5 m plus are commonplace, and 7 m ball mills are currently employed on at least two sites. However, there are several cases where large ball mills have not achieved design capabilities. One example was the 5.5 m diameter
