In this paper we present a generalization of the asymptotic solution o
f the batch grinding equation proposed by Kapur in 1970. It is shown h
ow this can be combined with the residence time distribution to give t
he particle size distribution of the product of a continuous grinding
process. The residence time distribution in a stirred bead mill has be
en determined by tracer experiments and used to propose a flow model o
f the mill. The results of batch grinding experiments of hydragillite
are combined with this flow model to successfully predict the product
size distribution in continuous grinding experiments.
