The movement can be divided into two regions, one is the active surface region, the other is the solid region, and it goes under the way of rolling and falling. The heat transfer process in rotary kiln goes with extremely complex physical and chemistry process. Considering the revolving of the kiln body itself and the special movement way of the materials, as well as the influence of the material reaction dynamic parameters, we have established the unidimensional axial heat transfer model for rotary kiln. Then according to the tentative data which has been published, we have testified that the unidimensional axial heat transfer model could reflect the
