  • An improved method for grinding mill filling measurement and

    2021年1月1日· Mill filling has a dominant effect on grinding mill performance (Apelt, Asprey and Thornhill, 2001), and therefore, its accurate measurement is vital for modelling grinding mill performance Measuring filling is also necessary to estimate the composition of the load for mill modelling: rock and slurry for AG mills; rock, balls and slurry for SAGThis leads to a narrower size distribution and significantly less slime compared to ball mills Lower critical speeds of 50 65 % and coarser product size Trajectory analysis also ensures grinding media is not being over thrown onto mill liners where the impact can lead to breakage of balls and liners therefore minimising operational costGrinding Media Growth Steel
