The lower fine grinder 11 drives the rotating shaft 19 to rotate on the first cross bar 18, so that the raw materials are crushed into powder by the lower coarse grinder 10 and the upper coarse grinder 8. The powder falls into the diversion groove 12 at the top of the upper fine grinder 9 and enters the lower diversion groove 12 through the material passing hole 13. The powder is further crushed into ultra-fine powder by the upper fine grinder 9 and the lower fine grinder 11. The ultra-fine powder falls into the collecting hopper 6 to be collected and discharged through the discharge pipe 7. By setting it in this way, it is convenient to double-grind and crush the feed raw materials, which can effectively reduce the proportion of large-particle powder, avoid the operation of repeated crushing, and is beneficial to improving the production efficiency of aquatic feed. While the rotating shaft 19 rotates, it drives the rotating rod 20 to rotate. The rotating rod 20 drives a plurality of brushes 22 to rotate in the collecting hopper 6. The brushes 22 sweep the powder on the inner wall of the collecting hopper 6 into the discharge pipe 7. At the same time, the rotating rod 20 drives the material pushing plate 21 to rotate in the discharge pipe 7, so that the powder in the discharge pipe 7 is continuously thrown out. By setting it in this way, it is convenient to quickly discharge the material, and can effectively avoid the blockage of the discharge pipe 7, which brings great convenience to the production of aquatic feed.
