2018-5-9  ABB also provided Collahuasi with drives and ring motors for one SAG mill and two ball mills. Powerful ABB gearless drives, rated at 15.5 mega-watts each, drive two eight-meter (26 feet) diameter ball mills that grind small pieces of ore at eleven revolutions per minute. However, the plant’s showpiece is the world’s largest gearless mill drive.
