What It Is The Optimun Speed For A Ball Mill

oct 19, 2006 for instance, if your jar had in inside diameter of mm and your milling media was 12.7 mm diameter lead balls, the optimum rotation would be rpm. optimum rpm .65 critical speed critical speed 265.qrt with dimensions in inches.

because you want the grinding balls to experience a free-fall motion, i.e. cataracting motion, would recommend you consider a rotational speed between and of the critical speed of the mill.

Common Equations For Optimal Performance

common equations for optimal performance too high of a speed or too light of a feed leads to reduction in tool life. speed is measured in feet per minute and is referred to as cutting speed, surface speed, or peripheral speed.
