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. The liner of this invention can automatically switch postures according to the operating conditions, forming a protrusion in the lifting zone to assist in lifting the steel balls, and retracting the protrusion in the impact zone to ensure effective impact of the steel balls on the material. This overcomes the technical contradiction of traditional fixed protruding liners being unable to simultaneously achieve both ball lifting and efficient impact.
