摘要： 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.

摘要： In a vertical roller mill including a fixed classifier, a proportion of coarse particles in a pulverized coal product is reduced. The vertical roller mill (10) includes a cyclone-type fixed classifier (20A) provided within a casing (11) for classifying fine powder having a small particle diameter by centrifugal force and discharging the classified powder to the outside. The fixed classifier (20A) is adapted to discharge the fine powder to the outside from a pulverized coal outlet (16) at an upper side through a lower end portion of an inner cylinder (24) provided inside a cone (21) by introducing a solid-gas two-phase flow into the inside from a fixed vane inlet window (22) opened on the cone (21) and swirling the solid-gas two-phase flow using a fixed vane (23) arranged in the vicinity of the inner side of the fixed vane inlet window (22). A deflector (26) is provided in the vicinity of the fixed vane inlet window (22) for strengthening the solid-gas two-phase flow delivered into the inside of the cone (21) from the fixed vane inlet window (22) in the downward direction.
