The ground material is mixed with water to form a porridge material, which falls from the grinding gap 5 to the discharge port 11 and is then discharged. The above structure facilitates reducing the particle size of the material, improving the grinding efficiency of the material, ensuring the grinding quality of the material, and also helps to reduce noise during the grinding process.

[0029] In this embodiment, the spiral conveyor shaft 4 conveys material from the feed cone 12 toward the discharge port 11 and into the grinding gap 5. The first grinding disc 2 and the second grinding disc 3 cooperate to fully grind the material, ensuring grinding accuracy while effectively reducing noise and component wear during the grinding process. A water supply pipe 15, located near the top of the first grinding disc 2, is used to supply water to the grinding gap 5, facilitating the thorough mixing of the water with the grinding and post-grinding material to form a porridge, which is then conveniently fed to the pigs.

[0030] In one possible implementation, please also refer to Figures 1 to 6 The spiral conveying shaft 4 includes a conveying main shaft 41 and a spiral blade 42 spirally wound on the outside of the conveying main shaft 41.
