[0021] The working principle of the present invention is as follows: first, corn material is added into the main body 1 through the feeding port 3, and the corn material moves along the guide slope 33 due to its own gravity, and then the first motor 5 is started, the first motor 5 drives the first rotating shaft 6 to rotate, the first rotating shaft 6 drives the grinding block 7 to rotate, and the grinding block 7 drives the first grinding protrusion 10 above it to rotate, and the corn entering the grinding channel 9 is ground. The width of the grinding channel 9 becomes smaller and smaller from top to bottom, so that the diameter of the corn powder particles is smaller and smaller, and the corn powder produced by grinding falls downward into the grinding groove 12, and the second motor 11 is started, so that the second motor 11 drives the first connecting rod 14 and the second connecting rod 15 to rotate respectively, the first connecting rod 14 drives the grinding plate 16 to rotate, and the grinding plate 16 drives the second grinding protrusion 17 below it to rotate, and the second grinding protrusion 17 grinds The corn flour in the trough 12 is further ground, and the scraper 18 is driven to rotate by the second connecting rod 15. The scraper 18 cleans the screen 19 to prevent the corn flour from clogging the screen 19. The ground corn flour passes through the screen 19 and falls into the lower part of the main body 1, and is finally discharged through the discharge port 21. When the corn flour particles obtained by grinding are too large, the corn flour is re-transported to the upper part of the main body 1 through the action of the suction pump 23 for secondary grinding. The dust generated during the grinding process is absorbed by the dust suction fan 27, and the dust enters the bag dust collector 28 through the dust suction hood 24, the first dust suction pipe 25 and the second dust suction pipe 26 in turn. After filtering by the bag dust collector 28, the gas is discharged through the exhaust pipe 29, and the recovered dust corn flour material is re-transported to the main body 1 through the recovery pipe 32.
