Screening equipment for graphene powder production

The invention relates to the technical field of screening for graphene powder production, and provides screening equipment for graphene powder production. A first support is arranged on the upper end face of a base, a turnover device is arranged at the upper end of the first support, a first screening device is arranged on the upper end face of the base, and a second screening device is arranged on one side of the first screening device and installed on the base; according to the graphene powder screening device, the dumping speed of graphene powder is controlled through the overturning device, the situation that the dumping speed is too high, a screen is blocked, and use of the device is affected is prevented, and through reasonable matching of the screen device, the powder pumping machine, the smashing rod and other devices, agglomerated graphene powder is separated, so that screening of graphene powder with different diameters is facilitated, and the screening efficiency is improved. And through reasonable
