[0021] The bottom spreading device of the preheater feed pipe is very important. The function of the spreading plate 3 is to allow the material to enter the next preheater pipe from the previous preheater to avoid rushing down with high kinetic energy, so that the material can have the most complete heat exchange with its airflow. Its working principle is to disperse the material into fine powder immediately after being blocked or rebounded by it, and evenly distribute it in the hot airflow, thereby improving the heat transfer efficiency within a limited time. The material is suspended instead of falling in a mass, and the material is dispersed on the cross section of the entire container entering.
