Highlights The dispersion properties in a continuous ball mill are analyzed theoretically. The Peclet number determines the residence time distribution. Trends derived from the theory are within agreement with data reported. Mill length and diameter are predicted to affect greatly the Peclet number. A proportional relation for the Peclet number is valid regardless of mill sizes.

AbstractComparison between anticipated and measured mean residence time (MRT) along with analysis of the shape of residence time distribution (RTD) curves provides the most useful and valid information about mixing properties within a ball mill operating at industrial scale. In this work, the RTD measurements were carried out for a primary ball mill in closed circuit with hydrocyclones at two ...

A size-continuous breakage kinetics model is postulated and supported with industrial grinding mill data. It is shown that the kinetics parameters include the effects of possible classification at the mill discharge. The estimated parameters were then used in the kinetics model to simulate the behavior of a grinding mill in open and closed circuit operation.
