The results carried out by both methods showed good agreement. It has been commonly accepted that the critical rotation speed is a function of a ball radius and a jar diameter.
The motion of the charge, that is the grinding media and the material undergoing grinding, within a mill is of considerable theoretical interest and practical importance, and for these reasons, has been the subject of considerable study by a number of workers, but, even so, no rigid and complete theory, covering all the aspects of the dynamics of the mill charge, has yet been Grinding Mills blogspot,Mar 20, 2017· MATHEMATICS OF GRINDING Critical Speed:-The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface.This is the rotational speed where balls will not fall away from the mill's shell. Mills are driven, in practice, at speeds of 50-90% of critical speed, the choice
Apr 14, 2012· In one textbook, it says that the critical speed is the minimum speed at which an object can complete the circular motion.
