## Dispersion properties for residence time distributions

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.
