Claims

[Claims for Utility Model Registration] (1) In a vertical mill in which a crushing roller is brought into pressure contact with the upper surface of a table rotatably supported with a vertical axis within a casing, A vertical mill characterized in that a sieve is provided, and the pulverized powder is allowed to fall through the sieve. (2) The vertical mill according to claim 1, wherein the sieve is provided on the outer periphery of the table. (3) The vertical mill according to claim 1, wherein the sieve is provided in the casing. (4) The vertical mill according to claim 2, wherein the sieve has an upward slope from the outer peripheral edge of the table toward the casing. (5) The vertical mill according to claim 3, wherein the sieve has a downward slope from the casing to the outer peripheral edge of the table. (6) The vertical mill according to claims 1, 2, 3, 4, and 5 of the utility model registration claim, wherein the sieve has slit-like holes. (7) The sieve has a missing part in a part of the entire circumference along the outer periphery of the table, and it is possible to discharge coarse foreign matter from the missing part, the scope of the utility model registration claims Paragraphs 1 and 2, Vertical mills according to items 3, 4, 5 and 6.
