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

Variable speed was required for the SAG mill Various options were considered to meet the specified speed range of 65 to 85% of mill critical speed and the final selection was the IES Hyper-Synchronous drive Slip Energy Recovery (SER) in conjunction with Wound Rotor Induction motors (WRIM) This was deemed to be the most cost effective
