2015-6-19 The critical speed of a rotating mill is the RPM at which a grinding medium will begin to “centrifuge”, namely will start rotating with the mill and therefore cease to carry out useful work. Ball mills have been successfully run at speeds between 60 and 90 percent of critical speed, but most mills operate at speeds between 65 and 79 percent of critical speed.

2015-8-6 The CRITICAL SPEED is the maximum revolutions per minute that the mill can revolve and still maintain performance. Naturally, the opposite is true as well, if the speed, is too slow the material will cascade too soon losing both impact energy and grinding

2015-2-1 A common turnaround point of 100 m/s is established in the graphical relationships between the critical thickness of chip formation and pile-up ratio with the grinding speed, which indicated that the material plasticity decreased with increasing grinding speed in the range of 20–100 m/s, and improved in speed range of 100–165 m/s. The chips of difficult to machine material GH4169 is characterized by
