Abstract: 본발명은, 분급(分級) 성능을높게유지할수 있는동시에, 바이오매스(biomass) 등에의한막힘이쉽게일어나지않는회전식분급기를제공한다. 회전분급핀(13)의상부에, 상기회전분급핀(13)의주위방향을따라간격을두고고정부재(27) 측을향해돌출된빗살형의돌출부(36)를가지고, 그빗살형의돌출부(36)의상단부와고정부재(27)의하면과의사이에제1 간극(42)이형성되고, 돌출부(36a)와그 돌출부(36a)와인접하는돌출부(36b)와의사이에형성되어있는제2 간극(43)이제1 간극(42)과이어져있고, 회전분급핀(13)의회전에의해, 제1 간극(42) 및제2 간극(43)을통하여빗살형의돌출부(36)의직경방향외측으로부터내측을향하는기류(氣流)가형성되는것을특징으로한다.

Abstract: [Problem] To provide a rotating classifier which can keep classification performance high and which can prevent blockages caused by biomass and the like. [Means for Resolution] The rotating classifier is characterized in that: comb teeth-like protrusion portions protruding toward a fixed member side are provided on top of rotary classification fins at intervals along the circumferential direction of the rotating classifier fins; a first gap is provided between an upper end portion of each of the comb teeth-like protrusion portions and a lower surface of the fixed member; a second gap formed between a protrusion portion and a protrusion portion adjacent to the protrusion portion is connected to the first gap; and an air stream flowing from the radial outside to the radial inside of the comb teeth-like protrusion portions through the first gap and the second gap is formed due to the rotation of the rotary classification fins.
