Provided is an ultrafine airflow classifying mill. The classifying mill comprises a raw material input end, a raw material output end, and a crushing area and a classifying area which are arranged between the raw material input end and the raw material output end, wherein the raw material input end is connected to a gas supply source, the crushing area and classifying area are directly connected and connected to the raw material input end through an external pipe, and coarse grains in the classifying area are discharged by a vacuum created at an input end of the external pipe, discharged into the raw material input end through the external pipe, and enters, together with input raw materials, the crushing area by airflow at the raw material input end. The ultrafine airflow classifying mill of the present invention effectively solves the problem that a part per million of residual coarse grains among powder is excessively high, and easily controls quality of the powder. In addition, the ultrafine airflow classifying mill of the present invention can directly replace an existing crusher and classifier mill which are online-produced, thereby improving the quality of a powder product with higher cost-effectiveness.;COPYRIGHT KIPO 2016
