I, No. 3 COMMINUTION, RESIDENCE TIME Introduction In the mathematical simulation of mills using "reactor" concepts (1,2) a prime parameter is the residence time distribution of material in the mill. Mardulier (3) has demonstrated a tracer method which is applicable to dry grinding of cement clinker in cement tube mills.
which itself might be turbulent, we would start recording a distribution of residence times and we would create the residence-time probability density or residence-time distribution. If the reactor is at steady state, and after we had collected sufﬁcient residence-time statistics, we expect the residence-time distribution to also
