▎ 摘　　要

NOVELTY - The device has a stirring box (7) fixed to a top surface of a support plate (8). The support plate is formed with a guide hole (10). A discharge pipe (9) penetrates the guide hole, and is fixed to the stirring box. A valve (11) is fixed to the discharge pipe. A collection box (12) is located below the discharge pipe. A lower hopper (5) is fixed to the stirring box. An inner side of the stirring box is formed with a mixing element (4) that is fixed to a bottom surface of a bearing frame (3). An output end of the bearing frame extends into the stirring box. A fixing element (6) is fixedly connected to an outer wall of the stirring box. USE - Magnetic field generating device for manufacturing a magnetic graphene. ADVANTAGE - The device improves effect of manufacturing graphene by facilitating changing of magnitude of magnetic field. DESCRIPTION OF DRAWING(S) - The drawing shows a side schematic view of a magnetic field generating device for manufacturing a magnetic graphene.
