[0028] The top of the main shaft 7 extends out of the top surface of the circular shell 1 and is provided with an adjustment mechanism 10. A feed pipe 11 is fixedly connected to the top surface of the circular shell 1. The adjustment mechanism 10 includes a top plate 12.

At this time, the movable shell 2 and the grinding block 8 rotate in opposite directions, and the grain is ground by the rotation between the movable shell 2 and the grinding block 8. After the grain is ground, it is discharged through the bottom surface of the movable shell 2, which can achieve efficient and convenient grinding operation of the grain.
