6.Ball Mill Critical Speed Mineral Processing Metallurgy A Ball Mill Critical Speed actually ball, rod, AG or SAG is the speed at which the centrifugal forces equal gravitational forces at the mill shell's inside surface and no balls will fall from its position onto the shell

7.If you have to reduce the SAG mill speed because of avoiding liner breakage, maybe it's better to modify the shell lifter design Low speed may cause decreasing capacity, higher steel ball and liner wear rate D80 of SAG mill may be finer because of more cascading action and less capacity which results in more retention time in SAG mill

8.conditions such as mill speed or balls filling degree, should limit the risk of projection The purpose of this paper is to further explore the issue related to the grinding efficiency There is probably more to be gained from media angle than a risk of breakage only Table I illustrates or quantifies the media charge angle for different liner designs at different mill speed but with constant
