The invention provides a steel slag combined grinding system and method. The steel slag combined grinding system comprises a fine grinding device and a superfine grinding device; the fine grinding device comprises a receptacle trough, a first vibration screen, a steel slag magnetic drum classificator, a buffer bin, a second rod mill, a magnetic separator and a third vibration screen; and the superfine grinding device comprises a metering device, a feeding belt conveyor, a steel slag vertical mill, a dust collector and a steel slag warehouse. Fine treatment of steel slag is achieved, space waste and environment pollution are reduced, the steel slag is subjected to multiple crushing, magnetic separation and screening, energy consumption can be reduced, slag and iron are separated, the iron and the slag can be secondarily utilized, and economic benefits are increased; multiple products can be formed through technologies such as multiple screening, magnetic separation and rod milling, anddifferent demands of mark
