On the basis of the masteries for the aluminum oxide ore pulp drying and calcination, a mathematical model was developed for simulating the process of heat transfer and the calcination of two-phase flow in a new type furnace designed by Zhongzhou Branch Company, China Aluminium Corporation Limited. The fields of velocity, temperature and pressure of the two-phase flow and the reaction time were gained by optimizing calculation under the condition of different operational parameters and geometric parameters. The effect of vent position velocity and atomization particle diameter on the drying and calcination technology of aluminum oxide ore pulp was discussed.
