▎ 摘　　要

NOVELTY - The device has a ring gear that is meshed with the sub-gears (11), and a lifting plate (7) is rotatably connected with the rotating shafts (12) through bearings. The rotating shaft is in interference fit with the corresponding sub-gear. The sub-gears mesh with a parent gear (10) together, and a main shaft (6) is provided with an upper grinding disc (15) in interference fit. An inner side wall of a lower grinding disc (16) is fixedly connected with a driving cylinder through a support. A number of convex flutes are fixedly connected to a side wall of a secondary shaft (8). The secondary shaft is provided with a section of the convex flute in a sliding connection with the driving cylinder USE - Graphene master batch grinding and processing device for use in biomedical and drug delivery applications. ADVANTAGE - The graphene master batch grinding and processing device has better grinding effect, higher processing efficiency, and automatically returns and re-grinds unqualified graphene. The manual return is avoided, labor intensity is greatly reduced, and the device structure is more compact, the operation is more convenient, and the manufacturing cost is lower.
