The energy consumption of the total grinding plant can be reduced by 2030 % for cement clinker and 3040 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended.
Composition metallic grinding media like carbon steel, forged steel, stainless steel or chrome steel grinding balls are best for some applications, while others require nonmetallic media made of alumina, ceramics, glass, silicon carbide, zirconium oxide or other specialized materials Request a Quote Grinding Media Literature (PDF)
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.
