摘要
天鸥矿业公司选矿厂使用CADI(碳化物奥铁体球墨铸铁)磨球后与高铬磨球相比,磨球单耗降低了31.02%-62.50%。电耗降低了6.29%。生产出的精矿细度要细,球磨机按新生成-75mm含量计算的处理量略高。运行180d后,磨机内几乎没有失圆和破碎的CADI磨球,也没有磨球堵塞格子板的情况出现。
After utilization of CADI( carbide austempered ductile iron)mill balls at the concentrator of Tianou mining company, the consumes of high chromium balls decreace 31.02% - 62.50%. The energy consumes decrease 6.29%. The grind fineness of the concentrates is fine. The yield of -75μclass for the mill increases little. The cracked and nonspherical CADI balls in mill undiscovered. The grids of mill were walled by CADI balls.
