[0029] The feeding mechanism is used to transport the filtered large-diameter crushed materials back to the inside of the mixing chamber 101. The feeding mechanism includes a conveying cylinder 2, an upper discharge pipe 3, an inclined pipe 14, a driving motor b25 and an auger. The conveying cylinder 2 is vertically installed on the outside of the crushing box 1, and the auger is rotatably installed inside the conveying cylinder 2. The driving motor b25 is installed on the conveying cylinder 2 and its output shaft is connected to the auger rotating shaft. The upper discharge pipe 3 is obliquely arranged at the top of the conveying cylinder 2, and the bottom end of the conveying cylinder 2 is obliquely connected with an oblique pipe 14 extending into the inside of the crushing box 1. The upper end of the oblique pipe 14 is opened, and the oblique pipe 14 is located directly below the bottom end of the bottom filter screen 9. The materials that are not completely crushed are discharged to the inner bottom end of the conveying cylinder 2 through the inclined pipe 14. The driving motor b25 is started to drive the auger to rotate. During the rotation process, the auger can transport the materials back to the inside of the mixing chamber 101 for secondary crushing.

[0030] The cleaning mechanism is used to clean the debris on the upper ends of the multiple filter screens 9. The cleaning mechanism includes multiple mounting rods 16, multiple bristles 17, multiple connecting rods 18 and a driving assembly.

The powder with a diameter that does not meet the requirements finally falls into the inner side of the inclined tube 14, and is discharged to the bottom end of the conveying cylinder 2 through the inclined tube 14, and starts. The dynamic drive motor b25 drives the auger shaft, which can transport the materials that do not meet the requirements back to the inner side of the mixing chamber 101, and then close the electric control valve 12 to crush the materials again; in order to increase the filtering speed of the filter 9, a vibration motor can be installed on the crushing box 1. When the material with a larger diameter is stuck on the surface of the filter 9, it will affect the permeability of the filter 9. At this time, the surface of the filter 9 needs to be cleaned. The driving member is used to drive the connecting rod 18 to move, and then drive the multiple installation rods 16 to move. The movement of the installation rod 16 drives the bristles 17 to move. During the movement, the bristles 17 can sweep the impurities on the surface of the filter 9 to one side to ensure the permeability of the filter 9.
