[0023] like Figure 3 As shown, a crushing hammer 13 is installed on the upper surface of the crushing wheel 6, and a wind wing 14 is installed on the lower surface of the crushing wheel 6.

[0024] Preferably, the guide tube 8 is an inverted cone tube, so that the distance between the lower end of the guide tube and the inner wall of the shell is greater than the distance between the upper end of the guide tube and the inner wall of the shell, thereby increasing the speed of the airflow moving upward and improving the classification efficiency.

The air inlet mechanism generates an air flow that enters the labyrinth sealing mechanism through the annular air inlet housing 14 and the air vent 15, thereby blocking large particles from entering the labyrinth sealing mechanism and improving the sealing effect. The air inlet mechanism can be a fan or the like. The annular air inlet shell 26 includes an annular plate 29, an inner ring fixedly mounted on the inner side of the annular plate 29, and an outer ring 28 fixedly mounted on the outer side of the annular plate, and the outer ring, the inner ring and the upper end inner wall 27 of the housing are fixedly connected together.

The driving gear, the driven gear and the servo motor are not shown in the figure, so as to adjust the angle of the feed inlet cover so that the feed slit is located on the left or right side of the feed inlet cover.
[0030] like Figure 1 and Figure 2As shown, a lower annular protrusion 19 lower than the lower surface of the annular air inlet shell is fixedly installed on the annular air inlet shell 26, an annular groove 20 cooperating with the lower annular protrusion 19 is provided on the upper end surface of the classifying wheel 7, and the labyrinth sealing structure includes an air inlet shell annular groove 21 provided on the lower surface of the annular air inlet shell 26, an annular protrusion 22 cooperating with the air inlet shell annular groove 21 is provided on the upper end surface of the classifying wheel 7, the air inlet shell annular groove 21 and the annular protrusion 22 are located outside the annular groove 20, and the vent 15 is connected to the air inlet shell annular groove 21. The cooperation between the lower annular protrusion 19 and the annular groove 20 prevents particles from passing through the labyrinth sealing structure. The annular air inlet shell 26 is connected to the air outlet end of the air inlet mechanism through the air inlet port 25 of the air inlet shell. In this embodiment, the lower end of the inner ring extends downward to below the lower surface of the annular air inlet shell, and also serves as the lower annular protrusion 19.
