Disclosed are an iron-ore-fines particle size sorting method and particle size sorting device. The iron-ore-fines particle size sorting device according to the present invention comprises: a fluidised bed dryer for drying iron ore fines by supplying a hot blast from below and at the same time discharging exhaust gas upwards, and for downwards discharging of iron ore fines that have not been dispersed by the hot blast; a cyclone separator which is connected to the fluidised bed dryer and is for separating out iron ore fines of more than a reference particle size that are discharged together with the exhaust gas; and a dust collector which is connected to the cyclone separator and is for capturing iron ore fines that were not captured in the cyclone separator. |
