▎ 摘　　要

NOVELTY - The device has a rotating cylinder (2) which is provided as a stainless steel seamless polish tube with special diameter. Two grooves are installed above an inner wall to connect with a main shaft (1) of a vertical agitating ball mill to transmit the torque. The bottom of the rotating cylinder is inserted between the inner tube and outer tube of a ball milling cylinder (3). The diameter of the rotating cylinder that the outer diameter of polishing tube to be required is same as inner diameter of outer tube of milling cylinder and inner diameter of outer tube of milling cylinder. USE - Ball milling device for providing pure shearing and peeling graphene. ADVANTAGE - The ball milling device is convenient to operate. The production cost is low. The shear efficiency of preparing graphene is effectively improved and the collision of grinding balls is reduced. The content of preparing graphene is increased, and the crystal lattice structure of graphene well is protected. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a ball milling method for providing pure shearing and peeling graphene. DESCRIPTION OF DRAWING(S) - The drawing shows the sectional view of a ball milling device. Main shaft (1) Rotating cylinder (2) Ball milling cylinder (3)
