介绍了提高硫化铜矿石自磨和半自磨过程处理能力的方法:1)从自磨机中,分离出粒度较大的难磨物料,并对它再破碎;2)向磨机筒体中添加钢球,提高磨矿介质的密度;3)同时向磨机中添加钢球及将粒度较大的难磨物料从磨机中排出和再破碎;4)减小最后一段破碎回路的筛分机筛孔尺寸。并叙述了使用这些措施后所获得的效果。
The methods to improve the processing ability of self-polishing and semi-autogenous grinding of copper sulphide ore are introduced: 1) From the self-mill, the coarse refractory materials are separated and crushed; 2) Adding steel balls to increase the density of the grinding medium; 3) adding steel balls to the mill simultaneously and discharging the refractory materials with larger grain size from the mill and then crushing; 4) reducing the sieve of the last crushing circuit Extension mesh size. The effect of using these measures is described.
