[0022] Compared with the prior art, the utility model provides a sand mill for ultrafine materials. By controlling the operation of the fan 10, the wind blown out from the fan 10 enters the curved pipe 13 along the telescopic flexible pipe 11 and the hard connecting pipe 12, and is finally ejected from multiple nozzles 14. The blown wind is directly blown to the filter plate, so that the materials blocked in the mesh of the filter plate are blown out and fall into the grinding barrel 8, so that the grinding operation can be carried out again later, and finally the materials can be fully ground for subsequent use.

[0023] In another embodiment of the present invention, please refer to Figure 3 and Figure 4 The right end of the grinding barrel 8 is fixedly connected with a support seat 21, and the top of the support seat 21 is fixedly connected with a guide rod 20, which penetrates the movable frame 18, and the movable frame 18 is slidably connected with the guide rod 20.

The circumferential surface of the threaded rod 25 is threadedly connected with a nut, and the nut is located at the right end of the sealing cover 24. When performing the grinding operation, firstly, the sealing cover 24 is installed along the threaded rod 25 so that the discharge hole 23 is sealed by the sealing cover 24, so that the material inside the grinding barrel 8 can continue to be ground; after the grinding is completed, the sealing cover 24 is removed, and the ultra-fine material ground in the grinding barrel 8 can be discharged through the discharge hole 23 and the filter plate; in order to make the ultra-fine material discharged more completely, the angle adjustment component can be controlled to change the angle of the grinding barrel 8, so that the ultra-fine material ground in the grinding barrel 8 can be discharged from the grinding barrel 8 more quickly and completely, and the material that is not fully ground in this process is still left in the grinding barrel 8, and then the angle adjustment component is reversely controlled to rotate and reset the grinding barrel 8. At this time, the filter plate 22 is observed. If part of the material is blocked in the mesh of the filter plate, the fan 10 can be controlled to blow the material blocked in the mesh of the filter plate back into the grinding barrel 8, and the grinding operation is performed again.
