A gear 14 is fixedly sleeved on the outside of the left-side supporting column 2. A driving assembly is arranged on the frame 1, and the driving assembly is used to pull the gear 14 to rotate. A feeding and crushing assembly is arranged on the top of the outer grinding block 3, and the feeding and crushing assembly is used for supplying and crushing materials.
[0022] The driving assembly is used to pull the gear 14 to rotate, so that the gear 14 uses the support column 2 to pull the outer grinding block 3 to flip back and forth intermittently. In this way, the graphite carbon nitride can be ground back and forth multiple times between the outer grinding block 3 and the inner grinding block 13 to make the ground graphite carbon nitride particles as uniform as possible. At the same time, the distance between the inner grinding block 13 and the outer grinding block 3 can be adjusted by the first hydraulic cylinder 8, so that the graphite carbon nitride can be more conveniently transferred during the back and forth grinding process.
[0023] Among them, the driving component includes a fixed block 17 and a rack 18, the fixed block 17 is fixedly installed on the frame 1, the gear 14 and the rack 18 are meshed with each other, a second hydraulic cylinder 19 is arranged on the fixed block 17, a carrier block 20 is fixedly installed on the output end of the second hydraulic cylinder 19, and the rack 18 is fixedly installed on the top of the carrier block 20.

In this way, it can be ensured that the graphite phase carbon nitride cannot be discharged during crushing and cannot flow back into the feed barrel 21 during grinding.
[0027] The working principle and use process of this utility model:
[0028] When in use, unscrew the cap 24, and put a certain amount of blocky graphite carbon nitride into the feeding barrel 21 along the feeding pipe 23. After the putting is completed, use the cap 24 to block the feeding pipe 23 again.

The second motor 27 is controlled to pull the blade 30 to crush the graphite carbon nitride in the feeding barrel 21. After a period of time, the graphite carbon nitride is crushed, the second motor 27 is turned off, and the third hydraulic cylinder 25 is controlled to push the plug body 29 upward, so that the crushed graphite carbon nitride in the feeding barrel 21 enters the inside of the discharge pipe 22. After the graphite carbon nitride in the feeding barrel 21 completely enters the inside of the discharge pipe 22, the third hydraulic cylinder 25 is controlled to drive the plug body 29 to block the top of the discharge pipe 22 again.
[0029] Start the first motor 10 to pull the inner grinding block 13 to rotate, and grind the graphite phase carbon nitride entering between the outer grinding block 3 and the inner grinding block 13. After all the graphite phase carbon nitride in the discharge pipe 22 is ground, the preliminarily ground graphite phase carbon nitride falls into the storage hopper 4. Operate the second hydraulic cylinder 19 to push the rack 18 to pull the gear 14 to rotate, so that the outer grinding block 3 flips 180°, and operate the first hydraulic cylinder 8 to pull the inner grinding block 13 to increase the distance with the outer grinding block 3, so that the graphite phase carbon nitride in the storage hopper 4 can quickly flow back to the inside of the discharge pipe 22. After that, operate the first hydraulic cylinder 8 to pull the inner grinding block 13 to reset, and operate the second hydraulic cylinder 19 to pull the outer grinding block 3 to flip 180° again, and start the second grinding of the graphite phase carbon nitride. Repeat the above steps many times to achieve multiple grinding of the graphite phase carbon nitride until the graphite phase carbon nitride is ground to a suitable particle size and the overall particles are relatively uniform. Open the two cover plates 6, and the ground graphite phase carbon nitride can be taken out for use.
