10. The method for grinding rare earth by using the rare earth luminescent anti-counterfeit printing material grinding device according to claim 1, comprising the following steps: crushing the reacted material into small pieces by a crusher, inputting the small pieces into a feed pipe (2), simultaneously, opening an external motor to enable a lantern ring (31) to rotate, enabling a ball body (33) to start rolling on the bottom surface of a transverse plate, arranging a torsion spring at the rotary joint of a connecting arm (32) and the lantern ring (31), enabling the ball body (33) to be directly abutted against the plate surface of the transverse plate, rotating a rotating outer shell (4) under the action of a connecting rod (34), keeping a gap between the rotating outer shell (4) and a grinding inner shell (5) along with the anticlockwise and clockwise rotation of the rotating direction of the lantern ring (31), enabling a grinding ball (51) and a material taking ball (52) to be in rolling contact with the rotating outer shell (4), the grinding shell (4) rotates, the grinding balls (51) start to contact materials, the materials are crushed through the rough surfaces of the grinding balls (51) and continuously collide and polish between the grinding balls (51), the grinding balls (51) grind the materials into smaller particles, the material taking balls (52) are rotated due to the rotation of the rotating shell (4), the grinded small particles are collected into the material taking holes (521) during rotation, the material taking holes (521) transport the small particle materials to the inside of the grinding inner shell (5) along with the rotation of the material taking balls (52), when the balls (33) approach the slope body (11), the grade-training arms (32) start to rotate by taking one end as an axis, and the other end extrudes the cornice plate (41) downwards, when the cornice (41) is depressed, the collar (31) rotates, thereby causing the grinding shell (4) to begin to rotate with floating up and down, so that the chances of collision of material between the grinding balls (51) increase.
