The implementation principle of the invention is as follows:

1 before the machine is operated, the size adjusting assembly 44 is adjusted according to the grain particle diameter so that the distance between the first grinding disc 41 and the second grinding disc 42 and the distance between the first grinding disc 41, the second grinding disc 42 and the grinding wall 43 reach the standard of the required grain particle diameter.

2, Grains are fed into the barrel shell 1 through the feeding component 2, the grains can be uniformly dispersed in the barrel shell 1 through the dispersion treatment of the feeding component 2, the grains are crushed by the rotating crushing blade 31 in the falling process, the grains meeting the requirements can be sieved on the screen 32 which continuously vibrates and fall into the grinding component 4 at the bottom of the barrel shell 1 for grinding, and the grains which do not meet the size can still be continuously crushed by the crushing blade 31 until the grains can fall into the grinding component 4 through the screen 32.

The grain particles fall between the first grinding disc 41 and the second grinding disc 42, the grain particles move towards the inner wall of the cylinder shell 1 under the action of centrifugal force, in the moving process, the grain particles are ground between the first grinding disc 41 and the second grinding disc 42, the rotation directions of the first grinding disc 41 and the second grinding disc 42 are opposite, so that the grain particles can be ground more fully and uniformly under the cooperation of the first grinding disc 41 and the second grinding disc 42, the grain particle diameter of the grain particles can be reduced until the grain particle diameter is changed to be in accordance with the required grain diameter size under the continuous grinding, and when the grain particles come to the edges of the first grinding disc 41 and the second grinding disc 42, the grain particles meeting the requirements can be blown up by adjusting the hot air force blown out of the drying facility, and the grain particles are sent out of the cylinder shell 1 and collected by a collecting device.

The embodiments of the present invention are all preferred embodiments of the present invention, and are not limited in scope by the present invention, so that all equivalent changes according to the structure, shape and principle of the present invention are covered by the scope of the present invention.
