· How many balls are in a ball mill? For example, the 100-150 tons ball mill has a maximum ball loading capacity of 9.5-10 tons. For the first time, 30% – 40% of the steel balls (120mm and 100mm), 40% – 30% of the medium balls (80mm) and 30% of the small balls (60mm and 40mm) were added.
The ball-milling treatment successfully reduced the size of the activated carbon to less than 500 nm. However, it was not successful in reducing the size below 100 nm. This finding is supported by Shan et al. (2016), where ball-milling at 550 rpm for 2 h for coconut shell-based activated carbon resulted in activated carbon with a size of 0.2 µm.
