Half autogenous mill lining board structure

The utility model discloses a half autogenous mill lining board structure, which belongs to the field of mining machinery equipment, and is strong in fracture resistance. The half autogenous mill lining board structure comprises a lining board body, a lifting board, reinforcing ribs and mounting holes, wherein the roots of the reinforcing ribs are arranged on connecting positions of the two sides of the lifting board and the lining board, the sides of the reinforcing ribs extend to the side of the upper surface of the lining board body from the side of the top portion of the lifting board, the mounting holes are arranged on the lifting board, and the reinforcing ribs and the mounting holes are arranged on the same cross section. The mounting holes are arranged on the lifting board, can prevent abrasive particles from forming material flows in the similar holes, and enhances fracture tendency of the lifting board, and the lifting board is thicker than the lining board body, and can enhance crack resistance of the lining board. The reinforcing ribs are arranged between the lifting board and the lining board body corresponding to the positions of mounting holes, the thickness of the reinforcing ribs is bigger than the mounting holes, can play the role of enhancing the lifting board and the lining board body, and can reduce deformation of the lining board body in thermal treatment.
