To provide a vertical roller mill having improved classification efficiency of a classifier that improves the classification efficiency of a classifier and uniforms the classification performance from the top to the bottom of the classifier by equalizing the flow rate distribution of fine powder flowing into the classifier.

In the vertical roller mill 1 that includes a housing 3 defining a classification chamber 16, a grinding table 5 provided on the bottom of the classification chamber 16, a pressure roller 11 pressed to the grinding table 5 to grind a bulk material, and a classifier 36 located in the upper part of the classification chamber 16 and arranged so as to pass ground powder in a state of a flow mixed with air, the classifier 36 has a rotation part 35 rotating around a vertical axis, the rotation part 35 has a predetermined number of blades 44 extending vertically and arranged with a predetermined pitch in the circumferential direction, and rectifier rings 45 are provided at positions vertically dividing the blade 44 into plural parts.
