Abstract
Disclosed is a vertical roller mill wherein a material fed to a casing is ground between a rotary table and a plurality of grinding rollers which are pressed against the rotary table and are rotated as the rotary table is rotated, the ground material being entrained by the upblast of heated gas or the like and discharged out of the casing. A bracket extended above the rotary table for carrying the grinding roller is pivoted at the side of the casing, and a pull-down means is connected with the bracket adjacent to the part thereof at which the grinding roller is supported. The bracket is pulled down by the pull-down means so that the grinding roller may be pressed against the rotary table.
