PROBLEM TO BE SOLVED: To provide a blade ring capable of preventing blocking of a gap between blades for blowing out of hot air, and to provide a vertical type pulverizing machine.SOLUTION: A blade ring 50 of this invention is provided by annularly arranging a plurality of blades 56 along an outer periphery of a rotary table 14 rotating in a casing 12 of a vertical type pulverizing machine 10, and in the blade ring 50, the blades 56 are each formed in a wedge shape in a cross-sectional view of a side surface of becoming thicker in an outflow side end part of the hot air than an inflow side end part of the hot air, and are slantingly arranged so that the outflow side end part of the hot air is positioned in the rear in the rotational direction of the rotary table 14 more than the inflow side end part of the hot air, and an outflow side gap of the hot air formed between the plurality of blades 56 is formed narrower than an inflow side gap of the hot air. |
