摘　　要：对酒钢选烧厂的磨矿介质进行了工业试验研究。结果表明,低铬铸球单耗为0.316 kg/t,高铬铸球单耗为0.214 kg/t,热轧钢球单耗为0.185 kg/t。采用热轧钢球作球磨机介质,碎球率极低,钢球经过一个阶段使用后,钢球硬度内外均匀,性能稳定,外形尺寸圆度好。Commercial tests were carried out to evaluate the performance of grinding media used in Concentration and Sintering Plant of JISCO. The results show that,unit consumption of low-chrome cast iron ball,high-chrome cast iron ball and hot-rolled steel ball is 0. 316,0. 214 and 0. 185 kg / t,respectively. The hot-rolled steel ball,as grinding medium in ball mills,can have an extremely low breakage ratio,and remain stable performance after running for a certain period of time,with the uniform ball hardness for the inner and outer parts,roundness in boundary dimension remaining unchanged.
