PROBLEM TO BE SOLVED: To classify efficiently by a small simple device by discharging fine grains out of a fine grain outlet while applying the vibration to a solid mixture in transfer chambers, also discharging rough grains out of a rough grain outlet simultaneously and classifying continuously the solid mixture into the rough grains and fine grains. SOLUTION: A solid mixture consisting of crushed rough grains and fine grains is flowed into anyone of transfer chambers (a) divided by rotating blades 27, 27. The solid mixture is pushed by the rotating blades 27 and rotated and moved in a casing 21. When the transfer chambers (a) are moved to an area communicating to a fine grain outlet 23 and a rough grain outlet 24, air pulsation is generated by the suction pressure difference between the pressure of a first blower device and the pressure of a second blower device 40 on the area. Fine grains are discharged out of the fine grain outlet 23 while the vibration is applied to the solid mixture in the transfer chambers (a) by the pulsation action, and simultaneously, rough grains are discharged out of the rough grain outlet 24 to classify the solid mixture into the rough grains and fine grains, respectively.
