In this article alternative forms of optimizing the milling efficiency of a laboratory scale ball mill by varying the grinding media size distribution and the feed material particle size distribution were investigated Silica ore was used as the test material The experimental parameters that were kept constant in this investigation was the
efficiency of the mill approximately 22 For the mill with lower mill load and higher speed the power draw of the different lifters also showed a slight difference The energy requirement of Hi lifter also varied slightly than the other lifters In this case the Hi lifter showed improvement in the energy efficiency of the mill approximately
The energy efficiency of ball milling in comminution Schellinger s calculated ball mill efficiency in dry or wet ball mill grinding ranges between 10 and 19 with the higher figure occurring at the optimal mill loading In terms of the Brace and Walsh surface free energy of quartz his results give a ball mill efficiency that is less than 0 5
