NOVELTY - The utility model claims a graphene raw material screening device, comprising a machine body, the left side of the top part of the machine body is connected with a feeding hopper; the top of the machine body right side is fixedly installed with a protective cover; the inner part of the protective cover is fixedly installed with a motor through a supporting block; the output shaft of the motor is fixedly installed with a driving gear. The utility model through the graphene raw material is poured from the feeding hopper, then falls into the interior of the screening frame; the motor drives the driving gear to rotate; the driving gear drives the driven gear and the screening frame to rotate the internal raw material for primary screening; because the screening frame rotates, the internal dispersing net plate can disperse the raw material, so as to improve the screening efficiency, and the screening hole diameter of the dispersion screen and screening frame surface is different, the impurity of the large particles after screening according to the design requirement left in the screening frame, it can be centralized cleaning, and screening the raw material secondary screening, increasing the screening quality and efficiency.
