The invention relates to a mechanical ball milling method for producing iron nitride magnetic powder. The method using ball milling and nitriding includes: selecting iron powder 2-80 Mum in average particle size as a raw material, placing the iron powder into a ball milling tank, selecting a ball-material ratio to be 10:1-50:1, charging nitrogen 0.1-0.5 Mpa, or selecting ammonia water as a ball milling medium and ball-milling at controlled ball mill speed of 300-1000 r/min for controlled ball-milling time of 5-100 h to obtain ball-milled iron powder; removing the ball-milled iron powder, placing in a thermal treatment furnace, introducing a protective atmosphere argon or nitrogen, annealing at 120-200 DEG C for 0.5-5 h; cooling to room temperature with the furnace, and taking out a sample. Through defecting and heating inside the magnetic powder during ball milling, a nitriding process is accelerated.
