Consumption of steel grinding media in mills A review
网页2013年8月1日 It is generally accepted that highly non-spherical debris from balls which break or spall due to manufacturing defects reduce ball mill grinding performance (Sinnott et al., 2011). More recently, Qian et al. (2013) have investigated the effect of grinding media shapes on the grinding kinetics of cement clinkers in balls mills. The specific
