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

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.
