▎ 摘　　要

NOVELTY - The device has a working table (1) whose upper part is provided with a grinding box (2) that is formed with a grinding conveying cavity (201). A middle part of a front side of the grinding box is fixed with an organic box that is provided with a motor. An output end of the motor passes through an outer wall of the grinding box and extends to an inner part of the grinding conveying cavity and coaxially connected with a packing auger shaft (302). A limiting block is provided at front and rear sides of a middle part of an outer side of filter sieve. A discharging port (9) is connected with front and back sides of a lower end of a left side of a filter box. USE - Graphene cathode material preparation device. ADVANTAGE - The graphene can be grinded and formed by the cylindrical grinding shaft for multiple times, and the grinding process is conveyed by the auger shaft, which not only improves the grinding efficiency, but also ensures the grinding effect, improves the use effect of the later investment battery, and avoids the condition that the service life is low and the factory is not qualified. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a graphene cathode material preparation device.
