| Abstract: | A new ‘back-calculation’ method of predicting the breakage and selection parameters has been developed using the solution of the cumulative batch grinding equation. As opposed to using the differential mass-size balance, the cumulative form inherently absorbs the noise present in individual mass fraction data. The estimation procedure renders a definite advantage due to the minimum occurrence of accumulation of the round-off error. |
