The buffer pad 22 can effectively absorb and disperse vibration energy, reducing the vibration transmitted from the baffle 1803 to the L-shaped support 1804, or from the L-shaped support 1804 to the baffle 1803.

[0023] The usage process of this utility model is as follows: First, the powder is added into the drum 14 through the hopper 16. The drum 14 is driven to rotate by the motor 17. The powder particles are blown apart by the air nozzle 1802 on the surface of the air jet pipe 1801. The baffle 1803 can guide the powder to tumble in the drum 14, so that the powder particles collide and disperse with each other. The processed powder enters the spiral blade 7 through the discharge cylinder 19. The central shaft 6 is driven to rotate by the motor 5. The spiral blade 7 on the surface of the central shaft 6 transports the powder to the mixing box 1. The powder is stirred by the stirring blade 8 at the lower end of the central shaft 6. The reverse paddle bottom stirring mechanism 13 is driven by the drive motor 12 to mix the powder. After the mixing is completed, the butterfly valve 10 is opened and the powder is discharged from the discharge port 9 through the screen 1101 at the bottom of the mixing box 1. The handwheel 1105 is turned to reduce the pressure applied to the extrusion plate 1104 by the screw 1103, so that the sleeve 1102 can be taken out from the discharge port 9.
