▎ 摘　　要

NOVELTY - The device has a connecting rod (14) provided with a mounting ring (13) that is inserted with a storage cylinder (12). A lower end of the storage cylinder is connected with a discharging pipe (11). Four supporting columns (6) are arranged at position of four corner of a lower surface of a bracket (1). A lower grinding plate (3) is welded with a lower grinding ring. An upper grinding plate (5) is welded to a lower surface of an upper grinding ring. A side of an upper end of a rotating plate (8) is inserted with a lower material pipe (10). A side of a fixing plate (2) is equipped with a groove (7). USE - Device for detecting production of graphene. ADVANTAGE - The device can conveniently grind a graphene material, and has smooth operation of the detecting work in convenient manner and convenient and rapid subsequent detection of the graphene.
