[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0021] like Figure 1As shown, a stepped material conveying device for a vertical mill comprises a shell 1 and a chute 2 arranged on the shell 1, the chute 2 is arranged obliquely, a step 3 is arranged in the chute 2, and a drying component for drying the material is arranged on the chute 2, and the drying component dries the moisture in the material.

[0022] When in use, the material enters the step 3 through the chute 2, and the drying component works to dry the material on the step 3 that falls in the chute 2. The setting of the step 3 is convenient for increasing the time that the material stays in the chute 2, thereby achieving stable drying of the material, which makes it easier to move the material.

[0023] Specifically, the drying component includes an air pipe 4, a nozzle 5 and a hot air source 6. The air pipe 4 is arranged on the chute 2, the nozzle 5 is connected to the air pipe 4, the air pipe 4 is connected to the hot air source 6, one end of the nozzle 5 extends into the chute 2, the hot air in the hot air source 6 enters the nozzle 5 through the air pipe 4, and then the hot air is introduced into the chute 2 to dry the material on the step 3.
