Rod mills how they function Mine

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
