A lifter for fastening a mill drum plate is made in the form of a bar of flexible material, mostly of wear-resistant rubber, with a metal reinforcement for installation of fasteners, the bar comprises a backing with a straight section. The metal reinforcement comprises a profile of U-shaped cross section and a strip. The profile height d is within 20 ... , and the strip is made of sheet metal 5 ...10 mm thick and has longitudinal hollow openings at both ends and edges, which are bent-under in the plane of cross section of metal reinforcement at an angle of 0° ... 15°. The distance h between the lower surface of strip and bar backing straight section is in the range 4 ...10 mm, the strip width G is 0.6... , which is made in accordance with the ratio A=K·D. The lifter height H is made in accordance with the ratio H=K·D. |
