The equations developed in this paper, based on the study of the behaviour of a solitary particle, can be very useful to estimate the mean residence time of granular material in a rotary dryer. Indeed, the mean residence time is a key parameter in the design of a rotary dryer and a good a‐priori evaluation of this parameter is necessary.
