As a preferred mode of the present invention, the rotating disk 4 further includes a connecting bar 13, the connecting bar 13 is welded to the outer ring of the rotating disk 4, and the rotating disk 4 is fixed to the The main rotating shaft 2 and the filter net 8 are between the connecting bars 13 .

As a preferred mode of the present invention, the cabinet 1 also includes a main discharge channel 14, the wall of the cabinet 1 below the annular groove 12 constitutes the main discharge channel 14, and the bottom of the main discharge channel 14 is The main discharge port 15, the main discharge channel 14 is arranged under the filter screen 8.

As a preferred mode of the present invention, the circular plane area formed by the filter screen 8 is smaller than the circular surface area of the cross-section of the main discharge channel 14 .

In the specific implementation process, after the raw materials are initially crushed in the primary crushing area, the raw materials that are initially crushed fall onto the filter screen 8. The filter screen 8 has a filter size, and the filter screen 8 filters the feed particles with a size larger than the filter size. And stay on the rotating disk 4, because the rotating disk 4 is bamboo hat-shaped, so the feed particles that are filtered and left on the rotating disk 4 slide down from the slope to the secondary feeding channel 6, in addition, the rotating disk 4 is driven by the main rotating shaft 2. Under the action of the centrifugal effect generated by driving the rotation, the feed particles falling on the rotating disk 4 are more likely to be thrown to the secondary feeding channel 6, but have already slipped to the secondary feeding channel 6 or are thrown under the centrifugal force. The large-sized feed particles to the secondary feeding channel 6 are also thrown to the outside of the rotating disk 4 under centrifugal action, which is equivalent to applying a transverse blade 7 set in the secondary feeding channel 6 to the large-sized feed particles The large-sized feed particles are pressed against the horizontal blades 7, and the feed particles thrown to the secondary crushing group are further cut and crushed under the rotation and cutting of the staggered horizontal blades 7 with high density. Feed granules become final feed granules, and slide out of the feed grinding machine from the auxiliary discharge channel 5 and the auxiliary discharge port 11.

For the secondary feeding channel 6, since the channel wall is wedge-shaped, and one end of the pointed end is located at the channel opening of the feeding channel, the feed that is initially cut will be separated into the channel of the feeding channel by the pointed end. The channel openings on both sides of the wall, without being blocked by the channel wall and hoarding in front of the channel walls on both sides of the channel opening. On the extension line of the channel wall, and at a distance of one transverse blade 7 from the channel wall, a small fixed rotating shaft 10 is provided. The height of the small fixed rotating shaft 10 is higher than the height of half the thickness of the annular channel cover 9 of the channel wall. The fixed rotating shaft 10 fixes the annular channel cover 9 . The annular passage cover 9 , the passage wall and the surface of the rotating disk 4 form the secondary feeding passage 6 together. The transverse blades 7 are arranged on the fixed rotating shaft 10, and the transverse blades 7 of the fixed rotating shaft 10 on both sides of the secondary feeding channel 6 are overlapped, and the overlapping density is high.

Similar to the channel wall, the connecting strip 13 has a triangular cross-section and its tip is upward, so that the feed that passes through the primary crushing zone and is initially crushed and whose size is smaller than the filter size will not be blocked by the connecting strip 13 and thrown into the secondary crushing zone. Thereby, it leaks from the filter screen 8 to the main discharge channel 14, and is discharged from the feed grinder through the main discharge channel 14 and the main discharge port 15.

For the main discharge channel 14 , the radius of the main discharge channel 14 is greater than the radius of the corresponding circular surface of the filter screen 8 , that is, the position corresponding to the wall of the main discharge channel 14 is the outer ring of the rotating disk 4 . It is worth mentioning that an annular protrusion is provided on the main discharge channel 14, and an annular groove 12 is provided on the lower side of the outer ring of the rotating disk 4, and the annular groove 12 is correspondingly embedded with the annular protrusion. Based on the above structure, when the rotating disk 4 rotates, the qualified feed particles leaked from the filter screen 8 will also be affected by centrifugal action and do centrifugal motion, and will flow to the main discharge channel 14 during the leaking process. The feed particles thrown to the channel wall will not penetrate into the gap where the wall of the main discharge channel 14 is connected with the rotating disk 4.
