[0044] The working principle of the above embodiment is as follows:

[0045] (1) When it is necessary to replace the grinding balls 309 on the right side of the inner cavity of the drum 6, the electric push rod 501 is started. The electric push rod 501 will push the first rack 502 to move. When the first rack 502 moves, it will drive the front first gear 504 and the front first rotating rod 503 to rotate together. The front first gear 504 drives the rear first gear 504 and the rear first rotating rod 503 to rotate together, and drives the second rack 505 to move through the rear first gear 504. By the first rack 502 and the second rack 505 moving together, the moving block 506 and the fixed block 507 are driven to move together. The fixed block 507 will drive the limit seat 508 to move at the same time. The feeding pipe 509 is driven by the limit seat 508 to move, so that the feeding pipe 509 is away from the connecting pipe 510. At this time, the transmission bearing 511 is also away from the rotating hole 512, and the grinding balls 309 can be taken out of the drum 6, which is convenient for replacement, beneficial to grinding different materials, and improves the grinding efficiency.

[0046] (2) After the material enters the inside of the drum 6, the motor 301 is started. The motor 301 drives the coupling 302 to rotate. The reducer 303 is driven to work through the coupling 302. The reducer 303 drives the second rotating rod 304 to rotate together. The second gear 305 is driven to rotate through the second rotating rod 304. The third gear 307 and the drum 6 are driven to rotate through the second gear 305. When the drum 6 rotates, the grinding balls 309 inside are driven to roll. The grinding balls 309 will grind the material in the drum 6 to make it crushed. After the material on the right side inside the drum 6 is crushed, it will enter the left side of the drum 6 and continue to be crushed under the action of the grinding balls 309, so that the material can be crushed to the required size.
