Vertical roller mill

A vertical roller mill, comprising:

• a rotary table that rotates about an axis by a driving force from a drive unit;
• a fuel supply unit for supplying a solid fuel to the rotary table;
• a roller for pulverizing the solid fuel supplied to the rotary table;
• a rotary classifier for causing a plurality of blades provided above the rotary table and disposed around the axis to rotate about the axis;
• and
• a ventilation unit for blowing oxidizing gas for supplying the solid fuel pulverized by the roller to the rotary classifier;
• the rotary classifier guiding, of the solid fuel pulverized by the roller, fine powder smaller than a predetermined particle size from an outer-circumferential-side space to an inner-circumferential-side space surrounded by the plurality of blades, and suppressing, by collision with the plurality of blades, an intrusion of coarse powder larger than the predetermined particle size into the inner-circumferential-side space;
• and
• the plurality of blades each being shaped in a manner such that there is no interference between a scattering direction in which the coarse powder that collided with the blades scatters and an intake direction in which the fine powder is guided to the inner-circumferential-side space, and the scattering direction is oriented upward relative to the horizontal direction.
