Sep 10, 2014· The failure of the Collahuasi motor was catastrophic and it occurred within months of commissioning. The Collahuasi motor was for a 40 ft SAG mill. The Antamina 38 ft SAG mill was also driven by an ABB motor and the hanger plates had not failed on that machine after several years of operation.
ABB also provided Collahuasi with drives and ring motors for one SAG mill and two ball mills. Powerful ABB gearless drives, rated at megawatts each, drive two eightmeter (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.
