但直径大于110mm时建议采用高碳铬钼低合金锻球,主要是考虑到大直径铸球破碎率可能会高些。锻球的 碳含量一般在1%左右,铬小于2% 。低铬铸球硬度一般应在HRc48左右,应尽可能的提高低铬铸铁球的硬度,以提高经济效益。我们和印度厂合作生产的低铬铸铁磨球硬度高达HRc55,且心部和表面硬度相差很少。无论电厂、矿山、水泥都具有很好的费效比。火电厂的磨球直径一般不要大于φ60mm。水泥和矿山应依据磨机直径、衬板的表面形状和入料粒度进行球径级配。级配原则只有一个:尽可能降低磨球的直径,因为,球磨机是研磨机,如果靠它去承担破碎作用哪怕仅仅是一小部分的,那也是十分不妥当的。

目前国内外广泛使用的为高碳高合金类球磨机铸造磨球和高碳低合金类锻造或铸造磨球,在火电厂、水泥行业等干法生产中,绝大多数使用高、低铬铸铁类磨球。而矿山类的湿法工艺中多应用高碳低合金类磨球。
