Abstract:
Provided is a vertical pulverizing apparatus capable of suppressing abrasion of throat vanes (40) and elongating their abrasion resistant lives to thereby increase working efficiency. The vertical pulverizing apparatus is characterized in that: a throat (4) is provided between a housing (32) and a pulverizing table (2) and has an annular flow channel which is surrounded by a throat inner peripheral wall (41) and a throat outer peripheral wall (42) and which is partitioned by a large number of throat vanes (40); and a slope part (43a, 43b) extending diagonally downward from an inner peripheral wall surface of the housing (32) toward a top end of the throat outer peripheral wall (42) and a horizontal part (44) extending from a bottom end of the slope part (43b) continuously to the top end of the throat outer peripheral wall (42) are provided so that top end surfaces (40a) of the throat vanes (40) and a top surface of the horizontal part (44) can be set at the same height.
