陕西楠木树氧化铅锌矿磨矿试验研究

Study on the grinding parameters of an Nanmushu lead-zinc oxides ore in Shanxi

摘要: 针对陕西楠木树氧化铅锌矿易粉碎的特点,进行了实验室磨矿介质与矿量比例、钢球配比的磨矿条件试验研究。确定了最佳的磨矿介质与矿量比例为10.56∶1,钢球直径Ø30、Ø29、Ø27、Ø18、Ø15 配比(%)为15.89∶5.51∶46.56∶19.40∶12.64,为工业试验提供了理论依据。

Abstract: The Lead-zinc 0xides Ore from Nan Mu Shu in Shanxi exhibits fragile problem,Theoretical research was made and laboratory experiments were undertaken in the two aspects of proportion of grinding media and ores and steel ratio.the optimal conditions of proportion of grinding media and ores and steel ratio were determined to be:proportion of grinding media and ores was 10.56∶1 and the Steel ratio of Ø30,Ø29,Ø27,Ø18,Ø15 is 15.89∶5.51∶46.56∶19.40∶12.64.It also provides theory data for the industry experiment.
