PROBLEM TO BE SOLVED: To provide a sizing/classifying apparatus whose removal efficiency of fine powder from small particles is improved without affecting the removal performance of fine powder from small particles by the input of the object to be sized. SOLUTION: The sizing/classifying apparatus 100, which has a screening member 108 for classifying the object to be sized into coarse particles and small particles smaller than coarse particles and in which a coarse particle recovering port 112 for recovering coarse particles and a small particle recovering port 114 for recovering small particles are formed, is provided with: a receiving part 110 arranged below the screening member 108 for receiving small particles passing through the screening member 108; an vibrating part 104 for vibrating the receiving part 110 continuously to convey small particles on the receiving part 110 to the direction of the small particle recovering port 114; and an air circulating part 118 for circulating the air between the screening member 108 and the receiving part 110 to the direction other than the conveying direction of small particles to remove fine powder stuck to small particles.
