  • What It Is The Optimun Speed For A Ball Mill

    Oct 19 2006 calculation of optimum speed depends on knowing the media diameter and jar id also for instance if your jar had in inside diameter of 90 mm and your milling media was 127 mm diameter lead balls the optimum rotation would be 98 rpm optimum rpm 65 x critical speed cascading action of the media stops
