摘　　要：对德兴铜矿大山选矿厂5 5m× 8 5m溢流型球磨机磨矿介质磨损规律进行研究 ,查明了平衡状态下磨机内钢球的粒度特性 ,得出了磨矿介质磨损规律数学经验模型 :r=1-(D/D0 ) 4 1 0 。并根据所得的数学经验模型 ,对添加球的合理球径比例进行计算 ,确定了较合理的添加球径比例为80 ∶60 ∶40 =30 %∶40 %∶30 %。The size features of balls in a mill at balance state were studied *'An empirical model,r=1-(D/D 0) 4.10 , for wear law of grinding media was set up *'Based on this model,the reasonable diameter ratio of addition balls was calculated and a reasonable ball addition system was determined
