Claims

[Scope of utility model registration request]

A cylindrical main body with a vertical axis, a table that rotates around a vertical drive axis within the main body, and a roll that rotates while being pressed against the top surface of the table and cooperates with the table to pulverize the material to be crushed. The classifier is arranged above the table in the main body and rotates coaxially with the table, and the classifier is arranged so as to form a gap along the inner surface of the main body below the vicinity of the lower end of the main body. a guide member,
In a roller mill in which large particles of the material to be crushed that have been supplied onto the table and are crushed are dropped onto the table again to be crushed, a plurality of compressed air outlets are provided in the main body near the upper end of the guide member. Vertical roller mill featuring:
