9. The method for using a pulverizing device for preparing thorium tetrafluoride material according to any one of claims 1 to 8, characterized in that: The method of use includes the following steps: A. First, the feed pipe (309) is connected to the feed pipe of the solid thorium tetrafluoride material, and the grinding component (2) is fed evenly through the feeding component (3). The steering wheel (303) is rotated clockwise, and the steering wheel (303) drives the threaded rod (306) to rotate outward along the inner cavity of the threaded hole (305). The threaded rod (306) moves and drives the baffle (304) to move toward one side of the inner cavity of the material control box (302), so that the opening of the inner cavity of the material control box (302) gradually becomes larger, so that the solid thorium tetrafluoride material can be added to the inner cavity of the shell (201) through the conveying motor (402) for grinding. The material discharge situation of the inner cavity of the silo (301) can be observed through the observation window on the surface of the silo (301). The size of the material discharge opening can be adjusted by rotating the steering wheel (303), thereby adjusting the material discharge amount; B. The output shaft of the grinding motor (206) rotates to drive the driving wheel (207) to rotate. When the driving wheel (207) rotates, it drives the driven wheel (208) to rotate through the belt. When the driven wheel (208) rotates, it drives the hammer (203) to rotate at a high speed in the inner cavity of the housing (201) through the transmission rod (209). When the hammer (203) rotates, it cooperates with the grinding plate (204) to grind the solid thorium tetrafluoride material. The powder falls into the inner cavity of the collecting hopper (202) through the screen (205). The solid thorium tetrafluoride material that fails to pass through the screen (205) continues to be ground by the hammer (203) and the grinding plate (204) under the action of centrifugal force. C. The powder in the inner cavity of the collecting hopper (202) falls into the inner cavity of the conveying pipe (401), and the output shaft of the conveying motor (402) rotates to drive the main shaft (404) to rotate through the reducer (403). When the main shaft (404) rotates, it drives the spiral piece (405) to rotate, so that the spiral piece (405) can drive the powder to move toward one end of the inner cavity of the conveying pipe (401), so that it falls into the inner cavity of the guide pipe (408); D. The airflow generated by the high-speed rotation of the centrifugal fan (406) drives the powder in the inner cavity of the guide tube (408) to be transported to the inner cavity of the spiral feed tube (502) through the connecting tube (407). When the powder enters the inner cavity of the separation bin (501) through the spiral feed tube (502), the particles in the thorium tetrafluoride powder fall along the inner walls of the separation bin (501) and the lower hopper (503) under the action of centrifugal force, and the powder floats upward and is discharged through the intermediate tube (504) and the discharge pipe (505). The particles fall into the inner cavity of the discharge box (601) and are collected by the distribution roller (603). The output shaft of the discharge motor (602) rotates to drive the distribution roller (603) to rotate, so that the particles can be discharged and recycled.
