|A ball mill brought down from Hoyt Lakes in many pieces is being loaded onto the Margaretha Green at the Port Terminal this week for shipment to India. A ball mill is a large steel drum used in the process of making taconite. Steel balls, in the drum, are used to break up hard rock, on its way to becoming marble-sized taconite pellets. Jindal Steel and Power Company in New Delhi bought the ball mill. They are getting all the steel balls as well. They were being lifted into the ship on Wednesday (above).
