▎ 摘　　要

NOVELTY - The device has a grinding box slidingly connected with a sliding rod, a sliding column, a mounting plate, a bottom plate, and a connecting rod (20). The sliding rod and the connecting rod are matched with each other to drive a grinding plate to extrude and grind the material when grinding box is vibrated. A front end of a rotating shaft is sleeved and fixedly connected with first bevel gear. The first bevel gear is meshed with second bevel gear. USE - Grinding device for graphene thermoelectric cement-based material. ADVANTAGE - The device solves problems of high cost and troublesome operation caused by separation of crushing and grinding process steps in preparation of the graphene cement-based cement base material, while eliminating manual turning tasks. The device satisfies better material vibration effects and high material discharging efficiency, and can automatically clean the residual scrap and dust after finishing grinding process so as to be convenient for subsequent usage. DESCRIPTION OF DRAWING(S) - The drawing shows an enlarged perspective view of a grinding device for a graphene thermoelectric cement-based material. 2Rack 19Third connecting rod 20Fourth connecting rod 28Third bevel gear 29Fourth bevel gear
