Abstract
In a vertical roller mill in which a fixed-type cyclone sorter is provided in a casing, the fixed-type cyclone sorter includes a conical member; a fixed-blade entrance window through which a solid-gas two-phase flow is introduced into the interior of the conical member; a flat plate-like fixed blade that causes the solid-gas two-phase flow to spiral; an inner cylinder into which pulverized coal is guided from the bottom end thereof toward the top end thereof by means of spiraling of the solid-gas two-phase flow; and a pulverized-coal exit through which the pulverized coal guided to the top end of the inner cylinder is guided outside the conical member, wherein the fixed blade is provided with a tip portion where a downward flow is increased for the solid-gas two-phase flow guided into the interior of the conical member from the fixed-blade entrance window.
