relation between torque and critical speed of ball mill

Critical rotation speed for ball-milling - ScienceDirect. In this paper, we found that the relation between critical rotation speed and ball-containing fraction is non-linear. And the relation has asymptote in the direction of ball-containing fraction increase, that is, critical rotation speed approaches to the value determined by Eq.
