Ironing Out Savings In Iron Ore Cleaning | Manufacturing

Iron ore contains a large amount of fine dust, which settles on furnace walls and acts as an insulator. At a flow rate of 700 tons per hour (TPH), this dust accumulates quickly. Because the customer's transfer systems are all open-belt conveyors, the dusty ore further compounds into an environmental problem for workers.
