武平铜银矿石高压辊碎磨-分选技术研究

Research on comminution and separation of copper-silver ore from Wuping by high-pressure roll mill

选取武平铜银矿石进行试验研究,探讨高压辊磨机在有色金属选矿领域的应用。试验制取常规破碎矿样、高压辊磨机破碎矿样和高压辊终粉磨矿样,主要从碎磨产品特性和选矿指标差异2个角度进行分析。通过试验和检测研究表明,从碎磨产品特性和对选矿指标影响2个角度来讲,高压辊磨机应用于碎磨作业均优于常规设备,尤其高压辊终粉磨系统具有巨大优势,其物料均匀,选矿指标远远优于常规破碎作业。

The silver-copper ore from Wuping was selected to conduct the experimental study so as to explore of the application of high-pressure roll mill in the field of non-ferrous .mineral separation. Samples of conventional crushed ore, crushed ore from high-pressure roll mill and ground ore from final high-pressure roll mill were prepared in the experiment, and they were analyzed from the characteristics of comminuted product and differences in separation indexes. The experimental study showed： speaking from the characteristics of comminuted product and influence on separation indexes, the high-pressure roll mill was superior to conventional comminution equipments in application to comminution operation, especially the application of high-pressure roll mill to final grinding system had a huge advantage whose material particle size distributed uniformly and separation indexes were much better than the conventional comminution operation.
