摘要： <正> A mathematical model to predict the operation behaviours of the rotary kiln process and to describe theaxial distribution of process variables along the length of the reactor has been developed in present work.Themodel is established based on the principle of mass and heat balance in the system under a steady state withthe consideration of kinetic characteristics of the processes.Four examples of the simulation processes in a pi-lot kiln and 3 commercial kilns by using the present mathematical model are given in this paper.The goodagreement between the predicted results and the measured data has been obtained.
