On some problems of producing grinding media by cross
2020年6月1日 According to Cleary (2001), grinding in ball mills is still far from being effective due to high consumption of electrical energy and steel (grinding media). Currently, the cost of steel balls amounts to 45% of the total cost of grinding materials in ball mills (Lameck, 2005). The remaining costs include energy consumption and ball mill lining.
