▎ 摘 要
NOVELTY - The utility model claims a graphene crushing screening device, comprising a primary crushing box and a secondary crushing box; the primary crushing box is fixedly set on the upper side wall of the secondary crushing box, and the primary crushing box is connected with the secondary crushing box through the discharging port; the upper side wall of the primary crushing box is fixedly provided with a feeding port; one end of the upper side wall of the secondary crushing box is fixedly provided with a first motor; the output shaft of the first motor is fixedly connected with a first rotating rod; the first rotating rod passes through the side wall of one side of the primary crushing box and is rotatably connected with the inner wall of the other side of the primary crushing box; and the side wall of the primary crushing box and the first rotating rod are provided with a matched bearing; the first rotating rod is fixedly provided with multiple groups of uniformly distributed crushing blades. The utility model has good crushing effect; it can collect graphene particles with different particle sizes; when it is actually used, it can design the inner diameter of the annular clapboard according to the needed size of the collected graphene particles, which is practical.
