Zusammenfassung:To inhibit wear of a crushing table and a crushing roller at a time when an object to be crushed is crushed.SOLUTION: A vertical type crushing device 100 includes: a crushing table 20 which is provided within a housing 10 and rotationally driven at a predetermined speed by a table driving device 110; and a crushing roller 30 which crushes an object to be crushed placed onto the crushing table 20. A wind speed of a gas sent from a gap S between an outer peripheral surface of the crushing table 20 and an inner wall of the housing 10 is adjusted to make a thickness of the object to be crushed between the crushing table 20 and the crushing roller 30 into a thickness which is a predetermined value or larger.SELECTED DRAWING: Figure 1 【課題】粉砕対象物を粉砕する際の粉砕テーブルや粉砕ローラーの摩耗を抑制することができる。【解決手段】筐体10内に設けられ、テーブル駆動装置110により所定速度で回転駆動される粉砕テーブル20と、粉砕テーブル20上に投入された粉砕対象物を粉砕する粉砕ローラー30と、を備える竪型粉砕装置100において、粉砕テーブル20の外周面と筐体10の内壁との間の隙間Sから送られる気体の風速を調整することにより、粉砕テーブル20と粉砕ローラー30との間の粉砕対象物の厚さを所定値以上の厚さとする。【選択図】図1
