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

回转窑内的传热过程伴随着十分复杂的物理化学过程，考虑窑体自身的旋转和物料运动的特殊方式，以及物料的反应动力参数等的影响，建立了回转窑内一维轴向传热模型，并根据已发表的试验数据对建立的一维轴向传热模型进行了验证，该模型可以反应出回转窑内各相沿轴向的温度分布趋势，这样结合热工分析，可以对回转窑的生产和运行给出适用的指导，并力图达到增产节能的效果。
