A grinding component 5 for secondary grinding of the crushed material is also provided at the bottom of the crushing cylinder 2. The grinding component 5 includes a guide shell 6 located at the bottom of the crushing cylinder 2 and surrounding the plurality of screening holes 4. A grinding cylinder 7 is connected to the bottom of the guide shell 6 via a plurality of hinges. The two sides of the grinding cylinder 7 are inclined outwards. The end of the grinding cylinder 7 away from the hinges is fixedly connected to the bottom of the grinding cylinder 7 via a convenient opening and closing component 8. The bottom of the grinding cylinder 7 is divided into a plurality of grinding arc grooves 10 by a plurality of partition plates 9. A rotating shaft 11 is provided at the bottom of the guide shell 6, and the rotating shaft 11 is provided with a grinding arc groove 10 for grinding materials. Multiple grinding arc grooves 10 correspond one-to-one with grinding rollers 12. The outer wall of the guide housing 6 is equipped with a first servo motor 13 that drives the rotating shaft 11 to rotate. The material enters the crushing cylinder 2 from the feeding hopper 3. After being crushed by the primary crushing component 1, it falls into the guide housing 6 through the screen hole 4 and enters the grinding arc grooves 10 of the grinding cylinder 7. The output shaft of the first servo motor 13 drives the rotating shaft 11 to rotate the grinding rollers 12, which perform secondary grinding on the material. The grinding cylinder 7 is opened by the easy-opening and closing component 8 and the hinge, so that the grinding cylinder 7 flips downward to discharge the material inside the grinding cylinder 7. Through the synergistic action of the primary crushing component 1 and the grinding component 5, the primary crushing and secondary fine grinding of the material are realized, which effectively improves the grinding efficiency and particle uniformity. The design of the easy-opening and closing component 8 makes it easy to open and close the grinding cylinder, facilitates cleaning and maintenance, and reduces downtime.

[0023] The grinding cylinder 7 is designed as a one-third arc shape, with flat plates on both sides of the arc. The material is subjected to centrifugal force and gravity inside the arc-shaped grinding cylinder, flows along the arc surface, and makes full contact with the grinding roller to achieve efficient grinding, reduce grinding dead angles, and improve grinding efficiency and uniformity.

[0024] The primary crushing component 1 also includes a rotating shaft 14 located inside the crushing cylinder 2. The outer wall of the rotating shaft 14 is provided with multiple crushing blades 15. A second servo motor 16 is installed at the end of the crushing cylinder 2 to drive the rotating shaft 14 to rotate. The output shaft of the second servo motor 16 drives the rotating shaft 14 to rotate, thereby driving the crushing blades 15 to cut and impact the material, completing the primary crushing, realizing the rapid crushing of large pieces of material, and improving the primary crushing efficiency.

[0025] The convenient opening and closing assembly 8 includes a support frame 17 located at the bottom of the material guide housing 6.

[0027] One side of the feed guide housing 6 is provided with a fixed strip 24 with a triangular cross-section. A second hydraulic cylinder 25 is installed in the middle of the fixed strip 24. The second hydraulic cylinder 25 is provided with a movable connecting plate 26. The movable connecting plate 26 is provided with at least two locking connecting plates 27. The outer wall of the grinding cylinder 7 is provided with a locking sleeve 28 that matches the locking connecting plate 27. The second hydraulic cylinder 25 pushes the movable connecting plate 26, so that the locking connecting plate 27 is inserted into the locking sleeve 28, thereby locking the grinding cylinder 7. Reverse movement unlocks it, making it easy to open. By matching the locking connecting plate 27 with the locking sleeve 28 to lock the grinding cylinder 7, vibration or displacement during the grinding process is prevented, ensuring the stability and safety of the grinding process.

[0028] During operation, material is fed into the crushing cylinder 2 from the feeding hopper 3. The second servo motor 16 drives the rotating shaft 14 and the crushing blade 15 to rotate, performing initial crushing of the material. The crushed material falls through the screen hole 4 into the guide housing 6 and enters the multiple grinding arc grooves 10 of the grinding cylinder 7. The first servo motor 13 drives the rotating shaft 11 and the grinding roller 12 to rotate, performing secondary grinding of the material. After grinding, the grinding cylinder 7 is opened through the convenient opening and closing assembly 8 to discharge the material or for cleaning. The convenient opening and closing assembly 8 controls the opening and closing of the grinding cylinder 7 by driving the moving strip 20 and the limiting support rod 21 through the first hydraulic cylinder 19; and by driving the locking connecting plate 27 to cooperate with the locking sleeve 28 through the second hydraulic cylinder 25 to ensure the stability of the grinding cylinder 7 during operation.
