The invention relates to a reverse osmosis (RO)-phase pneumatic separation system for steel slag micro-powder. The RO-phase pneumatic separation system comprises a feeding bin, a vortex powder concentrator, a cyclone, a bag dust collector, an induced draft fan system and an exhaust cylinder which are connected in sequence, wherein the vortex powder concentrator is connected with a first receiving bin through a discharging device; the cyclone is connected with a second receiving bin through a discharging device; the bag dust collector is connected with a third receiving bin through a discharging device; and the feeding bin is connected with the vortex powder concentrator through a screw feeder. According to the RO-phase pneumatic separation system, the RO phase of the steel slag micro-powder is effectively removed by adopting a physical method, and no additive needs to be added, so that the overall process cost is low, and the technical effects of improving the hydration activity of the steel slag micro-powder
