<p>PROBLEM TO BE SOLVED: To provide a vertical crusher in which hot air can be caused to uniformly pass through an annular passage between a rotary table and a casing, and can be directed to the center of the rotary table.SOLUTION: A vertical crusher 10 of the present invention is configured in such a way that: rotatable crushing rollers 16 are disposed on an upper surface of a rotary table 14; a raw material is supplied onto the upper surface of the rotary table 14 and crushed between the upper surface of the rotary table 14 and the peripheral surfaces of the crushing rollers 16; and resultant granules are conveyed by hot air supplied from an annular passage 40 provided between an outer circumferential surface of the rotary table 14 and a casing 12. The vertical crusher 10 includes: an armor ring 50 which is mounted in an inner wall of the casing 12 on the upper part of the annular passage 40, and curved from the inner wall of the casing 12 toward the upper surface center side of the rotary table 14; and an air flow guide plate 60 which is opposite to the armor ring 50 with the passage of the hot air between them, and curved following the armor ring 50.</p> |
