This invention relates to the field of ball mill technology, specifically to a steel-rubber composite liner for a ball mill. It comprises multiple arc-shaped liner units circumferentially and evenly arranged on the inner wall of a rotating cylinder of a ball mill. Each arc-shaped liner unit includes a first arc-shaped plate fixedly disposed on the inner wall of the rotating cylinder, and a second arc-shaped plate rotatably connected to the first arc-shaped plate.
