Efficiency And Grinding Media Filling Level

Efficiency And Grinding Media Filling Level

Apr 19 2013 About 60 years ago Fred C Bond George Krouse and a few others involved in comminution research conducted some preliminary studies on low filling level of grinding media in laboratory ball mills Initial indications were that there was a very good possibility for increased efficiency if ball mills were run with drastically reduced filling
