Here, the output port 111 is provided at a top side of the second grinding body 110, and the output port 111 communicates with the second grinding chamber 112.

Here, the number of blades in the first partial blade group 131 is larger than the number of blades in the second partial blade group 132; the second partial blade group 132 is the remaining blade group of the at least two blade groups except the first partial blade group 131; so that the first partial blade group 131 blocks the grinding medium in the second grinding chamber 112 from overflowing the output port 111 of the second grinding chamber 112 by arranging more blades. As an example, the number of the blades in the first partial blade group 131 is 8, and the number of the blades in the second partial blade group 132 is 4.

Here, the number of blades in the blade group of the at least two sets of blade groups gradually increases in the first direction; so that the grinding media in the second grinding chamber 112 are blocked from overflowing the output port 111 of the second grinding chamber 112 by the increasing number of blades. As an example, the number of blades in the blade group located on the cavity top side of the second grinding cavity 112 is 9, and the number of blades in the blade group located on the cavity bottom side of the second grinding cavity 112 is 3; the number of blades in the middle portion blade set is between 3 and 9.
