Mill speed is varied by changing the frequency of the current to the motor, allowing adjustments to the mill power draw as ore grindability changes. The gearless drive design was not applied to the mills in the mineral industry until 1981 when the then-world's largest ball mill, 6.5 m diameter and 9.65 m long driven by a 8.1 MW motor, was ...
