▎ 摘　　要

NOVELTY - The device has a crushing feeding mechanism (2) fixed on one side of the grading box. The crushing feed mechanism includes a feeding pipe (201). The feeding pipe is provided with a pair of crushing rollers (202). A grinding cone (203) is arranged between the pair of grinding rollers. A grinding sleeve (204) is provided on the outside of the grinding cone. The grinding sleeve is matched with a grinding cone, and the grinding sleeve and the grading tank are connected. A multi-stage grading mechanism (3) is fixed in the grading tray (1), and includes a grading rotating shaft (301). Multiple sets of uniformly distributed stepped grading screens (302) are provided outside the grading shaft. An anti-blocking brush (304) is connected between multiple sets of mixing scraper (303) close to the side of a stepped grading screen (302). USE - High-efficiency material graphene device. ADVANTAGE - The device improves the high efficiency of grading graphene of the material, avoids the multi-stage screen in the using process of the blockage condition, and greatly improves the material graphene device for grading the graphene of material grading processing. The device is convenient to support and limit the grading box through the supporting seat. The control box controls the operation of multiple groups of electromagnets so that the striker plate is moved and controlled by the cooperation of the electromagnet and striker plate, the discharge pipe is in the conductive state by the movement of a pair of striker plates, and then, the graphene-group stepped grading screen on the grading screen is guided into the dust-proof material collecting mechanism through the discharging pipe under cooperation of mixing scraping plate and the anti-blocking brush. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a high-efficiency material graphene device grading method. DESCRIPTION OF DRAWING(S) - The drawing shows a side sectional view of a high-graphene material grading device. 1Grading box 3Multi-stage grading mechanism 101Control box 102Supporting seat 301Hierarchical rotating shaft 302Stepped classification screen 303Mixing scraper 304Anti-blocking brush 305Grading motor 306Dispersing fan blade 307Material baffle 308Discharge plate 309Carrying plate
