Ball Mills - Mineral Processing & Metallurgy
Chrome: high-carbon: cast-iron = 100 : 140 : 170. Their average factory cost is: Chrome: high-carbon: cast-iron = 100 : 95 : 75. If, therefore, the freight charge is not taken into consideration, chrome steel balls show a lower cost per ton of ore ground than those of high-carbon steel, and the latter show a lower cost than those of cast- iron.
