NOVELTY - The utility model claims a roller spraying dryer, comprising a machine frame, a roller installed on the machine frame, and is connected with the machine frame through the machine cover to cover the roller on the machine frame. through the machine cover is provided with a spray gun, so as to spray the graphene on the roller, heating by the roller, graphene as to make the graphene uniformly. To sum up, graphene the action of the spray gun, it is uniformly adhered with the outer wall of the roller in the form of mist, and rotates continuously along with the cylinder, so as to cause the graphene to dry on the surface of the cylinder and form a thin sheet.
