Velocity Required for Loop the Loop – Dr. Sean .

Thus we have found the speed required to complete a loop the loop of radius (r). For example, if the loop had a 4 metre diameter (2 metre radius) then the velocity required to complete the loop would be (v = sqrt{5times gtimes 2}=sqrt{10g}approx 9.9). For convience we can approximate (sqrt{5gr}) as [sqrt{5times 9.81times r}=sqrt{49.05r}approx 7sqrt{r}.] — Many thanks to ...

Rod mills, how they function - Mine Engineer.Com

The Critical Speed is used for the determination of ball mill ideal operating speed. But for comparison, rod mills would operate between 50% to 95% of the critical speed. The faster the mill speed, the greater the wear on the rods and liners. So, the general rule of thumb for rod mills is to operate no faster than the speed that will obtain the desired product size.
