    Today, 40 ft. diameter SAG mills and 30 ft. diameter ball mills, both with motor powers of more than 22 MW, are commonplace as mine operators look for even larger equipment to achieve greater economy of scale. Mills with these larger drive capacities are driven exclusively by a “wrap around” ring motor (gearless mill drive)
