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. A driving structure is provided between the first and second arc-shaped plates. When the arc-shaped liner unit rotates with the rotating cylinder to the lifting zone, the driving structure drives the second arc-shaped plate to deflect and tilt upwards relative to the first arc-shaped plate.
