▎ 摘　　要

NOVELTY - The continuous multi-stage grinding and dispersing machine comprises a casing (1), a first-stage grinding mechanism (2), a second-stage grinding mechanism (3), and a feeding mechanism (4), where a first-level grinding mechanism is installed at the upper end inside the casing, and a second-level grinding mechanism is installed at the lower end inside the casing. A material transfer mechanism is arranged between the first-level grinding mechanism and the second-level grinding mechanism, and the outer wall of the casing is uniformly provided with through holes along its circumferential direction. The primary grinding mechanism includes a primary motor (21). USE - Continuous multi-stage grinding and dispersing machine for preparing graphene. ADVANTAGE - The continuous multi-stage grinding and dispersing machine separate the graphene whose size meets the standard and the non-standard before the subsequent grinding stage, so as to achieve the purpose of improving subsequent grinding efficiency and grinding quality. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of continuous multi-stage grinding and dispersing machine.
