[0026] In a natural state, the closed plate two 11 blocks one side of the discharge port 72, and the closed plate one 10 is arranged in a staggered manner with the inlet port 71, so that the auxiliary materials in the auxiliary material feeding hopper 5 fall into the inlet cylinder 7 from the inlet port 71.

[0027] A material feeding mechanism 2 is installed on one side of the rotary dryer body 1, which is used to introduce materials into the inside of the rotary dryer body 1 to realize the basic working process, and belongs to the conventional configuration of the rotary dryer body 1, which will not be explained in detail.
