  • Correlations for the grindability of the ball mill as a measure of its .

    The performance of a ball mill is measured with reference to the quantity of undersize or fines (amount of ground material passing through a 120 mesh screen) per revolution of the mill, collected for variation of each of the individual parameters. Finally, the calculated values of the fines in terms of the grindability of the mill.
