PROBLEM TO BE SOLVED: To provide a classifier allowing the enhancement of classification accuracy with a simple and compact configuration.SOLUTION: This classifier includes: a body casing 1; a classification rotor 2 provided inside the body casing 1; a single rotary shaft 7 mounted with the classification rotor 2; and a single drive source 10 for rotationally driving the single rotary shaft 7. The classification rotor 2 has a plurality of classification spaces 11, 12 disposed side by side along the axial direction of the single rotary shaft 7. The plurality of classification spaces 11, 12 respectively have air current discharge means 18-21 for discharging air currents from center parts thereof. |
