The middle interface of the connecting pipe 5 is located above the receiving tray 13, and the lower interface of the receiving pipe is located below the receiving tray 13. The receiving tray 13 and the grinding disk 15 are truncated cone-shaped, and the receiving tray 13 is larger at the top and smaller at the bottom, and the grinding disk 15 is smaller at the top and larger at the bottom. By providing a truncated cone-shaped receiving tray 13 and grinding disk 15, the raw materials can be accelerated by the inclination of the surface, and the grinding is completed when the feeding is completed.

[0023] Specifically, a raw material pump 6 is arranged above the storage box 3, a material receiving pipe 11 is fixed below the raw material pump 6, the material receiving pipe 11 is passed through the storage box 3, and a through hole is opened on the surface of the material receiving pipe 11, and a material discharging pipe 7 is fixed above the raw material pump 6.

The gas generated by the rotation of the fan blade 18 driven by the motor 19 is sent to the bottom of the box 1 through the gas pipe 9 on the side of the bellows 2. Inside the box 1, the gas inside the box 1 will blow up the ground raw materials, and after being blown up, the gas will be sent to the inside of the storage box 3 through the connecting pipe 5 above the box 1 and the filter plate 8. The powder that has not passed through the filter plate 8 will be sent to the inside of the box 1 through the connecting pipe 5 at the receiving tray 13 above the box 1, and will fall to the bottom of the box 1 through the groove 16 at the bottom of the receiving tray 13 to be ground again. When the ground raw materials in the storage box 3 need to be transported, the raw materials are sent out through the receiving pipe 11 and the discharging pipe 7 by starting the raw material pump 6.
