A classifier including a housing to take in air flow from below into a radially outer region of an inside space; a flow deflection portion to deflect the air flow toward a center axis of the housing; and an annular rotational portion disposed rotatably in a radially inner region positioned on a radially inner side of the radially outer region, of the inside space of the housing, and configured to classify particles which accompany the air flow. The annular rotational portion includes a plurality of rotational blades arranged at intervals around a rotational axis of the annular rotational portion. The plurality of rotational blades form an outer shape of the annular rotational portion forms an angle θ of not greater than 75° with a segment extended in a horizontal direction from the annular rotational portion outward in a radial direction, in a side view of the annular rotational portion.
