[0035] In the embodiment, the feed granulator device comprises a granulation box 3, two air suction pipes 4 arranged on the left and right sides of the granulation box 3, two connecting pipes 5 arranged on the left and right sides of the air suction pipes 4, two air inlet pipes 6 arranged on the left and right sides of the connecting pipes 5, a filter barrel 2 arranged on the upper end of the granulator 1, a sealing cover 15 arranged on the upper end of the filter barrel 2, a dustproof cover 13 arranged on the upper end of the sealing cover 15, a feeding hopper 9 arranged on the upper end of the dustproof cover 13, a mounting ring 7 arranged on the outer wall of the feeding hopper 9, a mold disc 22 arranged in the mounting ring 7, two compression rollers 26 arranged on the outer wall of the mold disc 22, and a plurality of rollers 21 arranged on the outer wall of the mold disc 22.

[0036] It should be noted that the two compression rollers 26 are fixed in position by the fixing ring 8, and the compression rollers 26 remain stationary and only rotate on the mold disc 22 when the mold disc 22 rotates. The outer wall of each of the two compression rollers 26 is provided with a plurality of grooves to increase the friction with the raw materials. A small hole is formed in the bottom end of the dustproof cover 13 to continuously add materials to the feeding hopper 9 while preventing dust.

[0037] The working principle of the above embodiment is as follows:

[0038] The feed raw material is put into the granulator through the feeding hopper 9, and after the feeding is completed, the dustproof cover 13 and the mounting ring 12 ensure the sealing of the feeding hopper 9 to prevent dust leakage. A small hole is formed at the bottom of the dustproof cover 13 for continuous addition of material into the feeding hopper 9. When the raw material enters the feeding hopper 9, the air suction ring 10 and the multiple dust suction pipes 11 start to work, which are connected to the dust removal system through the connecting square pipe 14 to effectively collect and process the dust generated during the feeding of the raw material. The raw material enters the granulation box 3 through the feeding hopper 9. At this time, the first rotating shaft 17 drives the guide plate 18 to rotate to uniformly distribute the raw material in a dynamic manner. The die plate 22 rotates under the drive of the first rotating shaft 17, and the raw material on the die plate 22 is extruded by the pressure roller 26 to form particles through the holes on the die plate 22. The outer wall of the pressure roller 26 is provided with multiple grooves to increase the friction with the raw material, which helps to form tighter and more uniform particles. During the granulation process, the air suction pipe 4 is connected to the air inlet pipe 6 through the connecting pipe 5 to suck the dust generated in the granulation box 3 into the filter barrel 2. The filter screen 202 in the filter barrel 2 filters the air, and the clean air is discharged through the air outlet slot 16, while the dust is intercepted on the filter screen 202. After granulation is completed, the particles are smoothly discharged from the granulation box 3 through the discharge pipe 19. The design of the discharge pipe 19 reduces the blockage and retention of the particles during the discharge process, improving the continuity and stability of the granulator 1.
