The gear drives the gear ring to rotate, and then the fixed ring drives the long rod to rotate, and the material is poured from the upper hopper through the fixed plate into the storage tank. When the long rod rotates, it drives the grinding disc to rotate, and then the material is fed from the grinding disc. The discharge holes are arranged in the gap between the grinding disc and the fixed disc. The grinding disc grinds the material, so that after the material is ground, the larger particles can be filtered out through the filter installed inside the storage tank and discharged through the discharge pipe, so as to facilitate the graded grinding of the material, which is beneficial to improve the processing effect of the device to a certain extent; when the long rod rotates, it drives the fixed rod to rotate, and a sleeve rod is fixedly connected to the fixed rod.
