VERTICAL MILL

PROBLEM TO BE SOLVED: To improve fluidity of crushed sand on a pan in a discharge room and to efficiently discharge the crushed sand by a small power by providing a water supply pipe in the discharge room and supplying a large amt. of water to the crushed sand in the discharge room from this water supply pipe. SOLUTION: In this vertical mill, a plurality of rollers 4 are provided above a rotating table 2 and these rotating rollers 4 are pushed in the direction of the rotating table 2 by means of hydraulic cylinder 3 to crush a raw material (a) between the rotating table 2 and the rollers 4 and crushed sand (b) being a product crushed thereby is made to be fallen into a discharge room 5 positioned below the rotating table 2 and is scraped up by means of a scraper 6 rotated with the rotating table 2 and is discharged from an outlet 9. In this case, a water supply pipe 10 is provided in the discharge room 5 and a large amt. of water is supplied to the crushed sand (b) in the discharge room 5 from this water supply pipe 10 to improve fluidity of the crushed sand (b).
