A filter screen 5 is arranged in the casing 1. During design, in order to improve the mechanical strength of the filter screen 5, the filter screen 5 is woven by steel wire. A material return port 6 is provided on one side of the filter screen 5, and a first electric control valve is provided at the material return port 6. The material return port 6 communicates with a return hopper 7 , and the return hopper 7 communicates with the feed hopper 2 through a feeding conveyor belt 8 .

A feeding screw 9 is arranged above the filter screen 5 , and the feeding screw 9 is driven to rotate by a second driving mechanism 10 .

Stirring rod 11 is arranged below the filter screen 5, and stirring rod 11 is vertically arranged, and stirring blade 12 is set on the outer periphery of stirring rod 11, and stirring blade 12 is dislocated from top to bottom, and stirring rod 11 is driven to rotate by the third driving mechanism 13 .

The box body 1 is also provided with a material inlet 14 and a material outlet 15 . Materials or solvents with smaller particle size can be directly fed into the box body 1 through the feed port 14 . The mixed material is discharged from the hopper 15. When designing, the feed port 14 and the discharge port 15 are located below the filter screen 5, the feed port 14 is provided with a second electric control valve, and the discharge port 15 is provided with a third valve. Electric control valve.

The principle of this scheme is as follows: the land fertilizer is put into the feed hopper 2, and the land fertilizer is added into the crushing mechanism through the outlet of the feed hopper 2. The first driving device 4 is started, and the first driving device 4 drives the crushing roller 3 to rotate. The crushing roller 3 bites to crush the land fertilizer. The crushed material falls on the filter screen 5 by its own weight, and the material with smaller particle size falls on the bottom of the box body 1 through the filter screen 5, and the remaining materials stay on the filter screen 5.

After all the materials in the feed hopper 2 enter the crushing mechanism to complete the crushing process, open the first solenoid valve, the second drive device 10 drives the return screw 9 to rotate, and the materials with larger particle size enter the return hopper 7 through the return port 6, and pass through the return hopper 7.
