Provided is a vertical pulverizing apparatus capable of increasing work efficiency by suppressing wear on a throat vane (40) and extending wear-resistance life. The present invention is characterized in that: a throat (4) is provided between a housing (32) and a pulverizing table (2), the throat (4) having an annular flow channel surrounded by a throat inner peripheral wall (41) and a throat outer peripheral wall (42), and the annular flow channel being partitioned by a plurality of throat vanes (40); and the invention is provided with an inclined part (43a, 43b) extending diagonally downward from the inner peripheral wall surface of the housing (32) toward the top end side of the throat outer peripheral wall (42), and a horizontal part (44) extending from the bottom end of the inclined part (43b) continuing to the top end of the throat outer peripheral wall (42), a top end surface (40a) of the throat vane (40) and a top surface of the horizontal part (44) being set at the same height. |
