A drum mill lining comprises plates of elastic material located on the inner surface of the mill drum with longitudinal lateral depressions, in which lifters are installed which are made in the form of a beam made of elastic material, which comprises lateral surfaces and a metal reinforcement connected to the beam material by means of vulcanization and fastening elements for connecting the lifter metal reinforcement to the drum body while pressing plates to the inner surface of the mill drum. The plates have a working surface that comprises two areas located at an angle α within 0° ... 15° to the horizontal plane. The length of inclination of area b is equal to 0.5 ... . The lifter is made of elastic material that has a conventional tensile strength for 2 ... 7 units higher than conventional tensile strength of plate material. Lifter has a metal reinforcement comprising U-profile and a strip. |
